Siena Memory Foam Mattress review 2024

News

The Siena Memory Foam Mattress is a budget boxed bed from Resident Home, the company behind two of the best mattresses in America: Nectar Mattress and the DreamCloud Hybrid. One of the obvious first attractions with the Siena mattress is the super-low prices: a queen size is on sale every month for just $399, which is absurdly low for a bed of this quality.

Our review panel slept on a Siena Memory Foam Mattress for nearly a month to see if it’s actually any good, and nearly everyone on the panel was impressed with the feel and finish. In fact, we think it’s the best cheap mattress around right now and is especially well suited to stomach sleepers (we’ll explain why shortly). During our testing period we evaluated the Siena Memory Foam Mattress for overall comfort, pressure relief, motion isolation, temperature regulation and edge support (a design feature that makes it easier to get in and out of bed).

The Siena Memory Foam Mattress’ main draw its low price tag – a queen is $699 at MSRP, but has been discounted since its launch and currently costs just $399. We don’t expect this to drop further come the Presidents’ Day mattress sales, as the price is already rock bottom. Despite its budget price, all of our testers thought that the Siena Mattress is built more like a mid-range mattress.

The 10″ Siena has three different foam layers that work together to contour your body, provide stability and support, and draw away body heat. Siena rates its mattress a medium-firm (6.5 out of 10), but our testing panel found it much firmer, regardless of stature or weight. We rate it a 9 out of 10 on the firmness scale (in line with today’s best firm mattress).

Our lead reviewer needed some time to break in the Siena Memory Foam Mattress when sleeping on her side, as there wasn’t enough give along the shoulders and hips at first. However, she found immediate relief when resting on her stomach, as the extra-firm feel of the Siena kept her hips level with the rest of her body.

Our taller side and back sleepers liked the subtle contouring and even distribution of their body weight, and our petite stomach sleeper was very comfortable. However, one of our heavier back sleepers who is used to sleeping on a softer foam mattress experienced some minor pain due to a lack of give around his lumbar. If you need extra cushioning on your side or simply prefer a softer bed, take a look at our list of the best mattresses for side sleepers instead.

We tested the Siena Memory Foam Mattress during one of the hottest summers on record and surprisingly didn’t break a sweat once. The temperature regulation here is much better than we had anticipated for a budget full-foam mattress. Still, chronically hot sleepers should consider investing in a cooling mattress with more advanced tech to keep night sweats at bay.

Another highlight of the Siena Mattress is edge support, which enabled our lead reviewer to comfortably get in and out of bed when her recurring back injury flared up midway through the testing process. Meanwhile, low motion isolation makes the Siena Mattress a great choice for co-sleepers with a fidgety partner.

You can trial the Siena Memory Foam Mattress risk-free for up to 180 nights, which is generous for a model in this price bracket. Otherwise, a 10-year warranty will apply if you choose to keep it. If you’re deciding between this and the lower mid-range Nectar mattress, we still think the pricier mattress has the edge – it suits a broader range of sleepers, and comes with a 1-year trial and Forever Warranty. But the Siena Mattress isn’t far behind, as its remarkable build quality and generous trial period far surpass what its budget price tag suggests.

Siena Mattress review: Materials

The 10″ Siena Mattress consists of three different layers of foam. At the base (5 on the diagram), is a shift-resistant cover, followed by a 5.5″ polyfoam stability layer (4) to keep the mattress in place. Right above that is two inches of transitional support foam (3) that’ll gently cushion your body whilst keeping you cool via its rippled design. Following that is a 2.5″ layer of gel-infused foam (2) that’ll adapt to your shape and draw away body heat.

On top is a soft, breathable polyester cover (1) woven with polyethylene to wick away moisture. It’s not removable for washing and there are no handles for maneuvering, but you wouldn’t really expect these kinds of extra features at such a low price.

Previously, for an extra $49, Siena allowed customers to add antimicrobial protection that the brand claimed kills and prevents 99.9% of bacteria that can affect the lifespan of a mattress. (This option is no longer available.) In any case, you’ll want to wrap your Siena Mattress in one of the best mattress protectors to also safeguard it from spills and stains.

Siena Mattress review: Price and deals

The Siena is firmly budget mattress territory, price-wise. It has been discounted since its launch – to begin with there was $200 off all sizes, but that has risen to $300 off. With the current offer, a queen size bed costs just $399.

Here’s the ‘official’ pricing for the Siena Memory Foam Mattress, and how much you can expect to actually pay:

Siena offers a 180-night trial with free returns plus a full refund if you’re not satisfied. (Learn how mattress trials work so you know just what to expect in case you want to send it back.) Otherwise, your bed will be backed by a 10-year warranty that covers faults and defects; know how mattress warranties work to understand how your purchase will be protected.

In this bracket you’ll also find the Allswell Mattress. The Allswell includes a 10-year warranty with purchase (like Siena) but has a shorter 100-night trial. Also, as a hybrid mattress, the Allswell may sleep cooler than the Siena, which is something to keep in mind if you’re prone to overheating at night.

Siena’s stablemate, the Nectar Memory Foam Mattress, is lauded as one of the best budget mattresses out there, as well as one of the best mattresses for college students. With one of the evergreen Nectar Mattress sales, the queen size costs $699. There’s also Nectar’s 1-year trial plus Forever Warranty, which slightly tips the scales in Nectar’s favor when it comes to overall value.

But if you only care about bringing home a high-quality mattress on the cheap, the Siena Memory Foam Mattress is a real bargain.

Siena Mattress: Firmness & comfort

Firmness and comfort are subjective. Thus, we’ve assembled a testing panel featuring individuals of varying builds and sleep preferences to help us share a broader range of perspectives when it comes to this criteria. (Our methodology for mattress testing further details how we reach these conclusions.)

Siena rates its mattress a 6.5 out of 10 on the firmness scale (medium-firm). However, our testing panel collectively rates it a 9 out of 10 on the firmness scale, which makes it a decidedly firm bed. This sentiment is shared by every member of our panel, regardless of their stature or weight.

Our lead reviewer is an average-sized side/stomach sleeper with a recurring back injury. She thought the Siena Mattress provided excellent front-side support, especially along the hips, but she didn’t feel as comfortable resting on her side until after the first week of sleeping on it. (There wasn’t enough give along the shoulders and hips at first.)

Most of our side and back sleepers were pleased with the balanced, full-body support of the Siena Mattress. So was our lone stomach sleeper, who liked that her hips didn’t sink below the rest of her body. However, one of our back sleepers – who weighs over 200lbs and typically sleeps on a softer foam mattress – lamented the lack of give in his lumbar, which led to a minor backache.

The Siena Mattress comes in only one firmness level. If you want a softer bed, we’d recommend the Nectar Memory Foam Mattress or the Tuft & Needle Original Mattress. We’ve tested each, and they’re both closer to the medium-firm feel Siena promises. Alternatively, you can add one of the best mattress toppers to soften things up, too.

Siena Mattress review: Performance

For one month, we slept on a twin Siena Memory Foam Mattress, evaluating it in key areas of performance: pressure relief, motion isolation, temperature regulation, edge support, and durability. We’ve also rated the ease of setup and overall value for money.

To supplement our lead reviewer’s opinion and feedback from our experienced testing panel, we’ve also analyzed the hundreds of reviews this brand-new mattress has already accumulated to provide a more complete picture of what it’s like to sleep on this budget foam mattress. Here’s what we found…

Setup

A twin Siena Mattress weighs 42lbs, and wasn’t too bad for our lead reviewer to haul by herself. A queen mattress weighs 68lbs and a king is 85lbs, so you’ll likely want a friend or family member to assist you there. Keeping in theme, this budget mattress doesn’t offer a supplementary service for setup or removal of your old bed. (Find out how to dispose of a mattress safely and legally.)

Included with the Siena Mattress is a small informational booklet plus an ergonomic pocket blade. which we used to tear off the vacuum-sealed plastic. (There were also quite a few silica gel packets for freshness so be careful if they hit the floor, especially if you have pets or small children.)

The mattress began to expand as soon as we unfurled it and it fully took shape about a minute later. We had to smooth some lumps in the top cover at first – understandable, given how compressed the foam was before we unpacked it. Although it was very firm from the start, vacuum-sealed mattresses take time to completely inflate. (Per Siena, the process takes between three and five hours.) Thus, we recommend waiting a few hours after setup before heading to bed.

Siena uses CertiPUR-US-certified foam in its mattresses. In other words, it doesn’t contain ozone-depleting materials nor is it heavy in volatile organic compound (VOC) emissions – the reason for the unpleasant but otherwise harmless ‘chemical’ odor associated with off-gassing.

Full-foam mattresses are prone to off-gassing, but to our pleasant surprise, the Siena Mattress emitted no obvious smell from the time we unwrapped it. We did have the window cracked slightly, which likely could have helped diffuse things, but even when we lay on the bed we didn’t smell anything off-putting.

The construction of the Siena Mattress includes a soft top foam layer (to cushion joints), a denser middle foam layer (for support), and a sturdy base foam layer (to provide stability). The brand claims its bed is designed to hit the ‘sweet spot’ for all types of sleepers when it comes to comfort and relief.

We tested the pressure relief of the Siena Memory Foam Mattress by placing a 56lb weight in the center of the bed. The weight did not sink very deeply into the mattress, nor was there an indentation on the surface once we removed it.

Meanwhile, our human testers found the pressure relief for the Siena Mattress adequate, although a brief adjustment period was needed for some of us. One of our taller combi (side/back) sleepers liked that her shoulders and hips didn’t hurt when she rested on her side, an issue she’s having with her current mattress. She also felt her weight was evenly distributed when she was on her back.

Conversely, one of our back sleepers said the Siena Mattress didn’t have enough give along his lumbar, which resulted in a sore back. Our lead reviewer felt similarly when laying on her side, although she’s been able to find some relief since breaking in the mattress.

The Siena Mattress doesn’t have as much of a ‘hug’ as other foam mattresses we’ve tested. If your joints need more cushioning (especially if you sleep on your side), consider a plush mattress like the Helix Sunset or the Linenspa 12-Inch Hybrid Mattress.

A twin mattress can only support one person comfortably, so we initiated several drop tests to evaluate the motion transfer of the Siena Mattress.

We dropped a 10lb weight from three different heights at approximately 25in away from an empty wine glass. We simulated a partner tossing and turning in bed (4in high), a partner getting in or out of bed (8in high), and a partner jumping in or out of bed (12in high).

The wine glass hardly moved during the first two drop tests, so you’re unlikely to be disturbed if your co-sleeper fidgets or gets into bed before or after you do. The glass jiggled a bit more during the final drop test, but this was still quite minimal. Notably, the empty glass did not fall during any of our drop tests.

Our findings show that it’s unlikely your partner will disrupt you if you share a Siena Mattress. Thus, we recommend it for couples with differing sleep styles and routines.

Memory foam mattresses are notorious for trapping and retaining heat, so they’re not often the right choice for hot sleepers. However, the best foam-based cooling mattresses boast materials that are designed to regulate temperature, which makes them better suited for anyone who overheats at night.

The Siena is not a cooling mattress per se, but it’s designed to wick away moisture and draw away body heat. The top cover is made of polyester woven with polyethylene to keep night sweats at bay. The top foam layer is infused with cooling gel, while the rivets in the middle foam layer create pockets to generate airflow.

We were impressed with the temperature regulation capabilities of this budget full-foam mattress. The Siena did an outstanding job of keeping our hot sleepers comfortably cool, especially during a sweltering Mid-Atlantic August. Our lead reviewer did not have a single morning when she woke up sweaty, regardless of the sheets she had on the bed or the temperature outside.

The 180-night trial means you can test the Siena Mattress across two seasons so you’ll be able to experience how comfortably you’ll sleep during a shift in temperatures. If overheating is your primary sleep concern, however, we’d still recommend a proper cooling mattress like the Cocoon by Sealy Chill, which costs more than the Siena but is still very affordable.

But for such a small price, the Siena Mattress exceeded our expectations. We slept comfortably the entire month.

To test the edge support of the Siena Memory Foam Mattress, we put a 56lb weight on the edge of the mattress in the middle of the perimeter. We also had every member of our testing panel sit on the edge of the bed – along the center perimeter and on either corner.

When we placed the 56lb weight on the edge of the Siena Mattress, it compressed about an inch and there was no danger of the weight rolling off the bed. That’s good news if you or your partner somehow move towards the edge while you sleep, as you’re unlikely to fall out of bed.

Everyone in our testing panel was impressed with the edge support of the Siena Mattress. From our most petite sleeper to our largest tester, the Siena comfortably supported them whether they sat on the corner or along the perimeter. The bed didn’t compress too much at all when we sat along its edges, so it was easy for us to get up.

One may suggest that edge support on a twin bed isn’t as much of a priority compared to a queen or king, but we feel it’s an important factor regardless of size. Notably, anyone with mobility issues may need to sit on the edge of their bed in order to comfortably enter or exit it. Our lead reviewer had to do just that during testing due to a recurring back injury – and was able to without further hindrance thanks to the superb edge support of the Siena Mattress.

The Siena Mattress was released in March 2022, so we’ve no long-term data to show when it comes to durability. We also haven’t had the mattress all that long ourselves, but our first impressions are very positive. The Siena is sturdy and doesn’t feel like a budget mattress. Then again, it is manufactured by Resident, the parent company of renowned brands Nectar, DreamCloud, Awara, and Cloverlane.

Going by how long a mattress lasts on average, you can expect to get a good 7 to 10 years out of the Siena Mattress. The jury is still out on just how well the Siena holds up over time, but you can prolong the lifespan by knowing how to clean a mattress.

Siena’s mission is to deliver great sleep to everyone, regardless of budget. The brand promises to “never compromise on the quality of materials or design [for a] truly comfortable mattress that correctly supports your body.” Siena invested much of its capital into procuring high-quality materials – and cut out “flashy TV adverts” and brick-and-mortar sales.

That laser focus on materials has culminated in a budget mattress that looks and feels like a mid-range bed. Whether you need a new mattress for yourself ASAP or want to refresh a guest room, the Siena Mattress is a fantastic option, especially when you consider the going sale price for a queen is only $499.

The trial length for a budget mattress usually ranges from 30 to 100 nights, so the 180-night trial that comes with the Siena is comparatively generous. The 10-year warranty is on par with the industry standard. We’ve yet to see any freebie offers a’la Nectar, which we still think offers the best overall value-for-money…but the Siena is nipping right at its heels.

To offer our readers a well-rounded perspective, we’ve analyzed user reviews from verified Siena customers. This will even expand upon the feedback of our six-person testing panel – which is still a very small sample size relative to how many have (and will) sleep on this mattress.

The Siena Memory Foam Mattress is rated 4.5 stars out of 5 from over 2,200 reviews on the Siena Sleep website. (Roughly 80% of those comments are five stars.) Currently, there’s no way to filter reviews according to customers’ sleep styles or top concerns, but you can sort them by rating, date, and helpfulness.

The most helpful positive comments say the Siena is easy to set up, and several customers credit it for alleviating their aches and pains. “We were having back issues before buying this mattress, so I decided to take the leap… it has been a lifesaver,” reads one 5-star review. Another sleeper with chronic pain says of the Siena mattress, “My body feels so balanced and well rested with no tossing and turning.”

Negative feedback is few and far between for the Siena Mattress. Most reviews below five stars mention perceived firmness – the bed is either too soft or too hard, depending on the individual. Of course, firmness is subjective and a reason why Siena (and other top mattress companies) include at-home trials. A few less-than-favorable reviews also suggest that temperature regulation could be better. That differs from our experience but it’s still something to consider if you sleep warm

Should you buy the Siena Mattress?

If you want a top-notch bed on a tight budget, the Siena Memory Foam Mattress will absolutely deliver. Unlike many mattresses in its price range that only contain two foam layers, the Siena consists of five layers for a sturdier, more supportive bed. The 180-night trial is another great perk – budget mattresses usually offer between 30 and 100 nights to try it.

Based on our testing, the Siena Mattress is much firmer than the brand claims. If you’re hoping to sink deeply into your foam mattress, you might be disappointed here. The Siena has a subtle cradling characteristic of a hybrid. Most stomach sleepers should be well supported along their hips, but some back and side sleepers may not find the pressure relief they need along their lumbar, shoulders, and hips right away. (Nectar or Tuft & Needle’s memory foam mattresses may be more their speed.)

Hot sleepers, on the other hand, are bound to be pleasantly surprised by Siena’s temperature regulation. We didn’t break into a sweat once during our testing period, even during another sweltering summer. Despite its better-than-average performance in this category, for chronically hot sleepers we’d recommend reading our Cocoon by Sealy Chill Mattress review for an affordable cooling mattress that’s also among the best in its class.

If you share a bed with a restless partner, the Siena Mattress is packed with dense foam that’ll barely budge, no matter how fidgety your co-sleeper is. Edge support is also excellent, which will benefit individuals with mobility issues who need to sit on the edge of their bed in order to get up or lie down.

The Siena Mattress is poised to become the best budget memory foam mattress money can buy. It helps that Siena is a part of Resident’s line of renowned mattress-in-a-box brands, which means consumers can expect nothing less than the highest quality build and materials. Along with stablemate Nectar, the Siena Memory Foam Mattress is proof that the best mattresses don’t have to cost a lot.

Type: Bed-in-a-box

Firmness (1-10): 6.5

Materials: Memory foam

Height: 12 inches

MSRP: $599 – $1,338

Trial/Warranty: 365 nights/Lifetime

The Nectar Memory Foam Mattress has a similar construction to the Siena: a top layer of adaptive gel-infused foam, a breathable transitional foam layer, and a sturdy foam base with a shift-resistant lower cover. But the Nectar is a taller, plusher bed with a ‘hug’ that’s typical of memory foam beds. The Nectar also has a quilted cooling cover, as opposed to the knit polyester cover of the Siena, which should add to that softer feel. You’ll find more details in our full Nectar mattress review.

When it comes to value for money, Nectar has Siena beat right now. Regular sales knock prices to as low as $399 for a twin ($799 for a queen) and often include up to $499 in free bedding. Standard with all Nectar mattresses is a Forever Warranty plus a 1-year trial, which are both industry-best amenities. Of course, if you’re looking for the lowest price outright, you’ll come out on top with the Siena.

Tuft & Needle was among the first mainstream bed-in-the-box brands to hit the internet and has since developed a reputation for its affordability and superior customer service. This American-made bed isn’t as cheap as it used to be thanks to inflation-driven price increases, but T&N is still a fine choice for anyone who doesn’t want to overspend on an uncomplicated foam mattress. (Current Tuft & Needle mattress sales knock a twin-sized Original bed to $596, a 20% savings.)

We recommend the Tuft & Needle Original for couples thanks to its excellent motion isolation. Hot sleepers, on the other hand, won’t find much relief as this bed slept warm for us during our Tuft & Needle Original mattress review. Edge support is also lacking, especially compared to the Siena Mattress. Still, nearly 25,000 T&N customers agree that the Tuft & Needle Original is a bonafide 5-star mattress.

Type: Bed-in-a-box

Firmness (1-10): 6.5

Materials: Memory foam

Height: 10 inches

MSRP: $769 – $1,539

Trial/Warranty: 100 nights/10 years

Thanks to frequent Cocoon by Sealy mattress deals, the Cocoon by Sealy Chill is one of the most affordable cooling mattresses out there, with a queen selling for $799 after 35% off. Sealy also includes up to $199 in free pillows and sheets to save yourself the trouble of purchasing new bedding. We’d be remiss to overlook its advanced cooling tech, from a phase-change cover that’s cool to the touch to a layer of Extra Chill cooling memory foam infused with Sealy’s PCM Chill technology.

Similar to the Siena, the Cocoon by Sealy may be too firm for some, but our testers found it had very good pressure relief. While the Siena kept us good and dry every night, chronically hot sleepers will find more value in the Cocoon by Sealy Chill, a mattress that’s specially designed to keep you cool for less than $1,000.
