The Saatva Classic is a dual-coil innerspring with a 3-inch Euro pillow top, three comfort levels and a 365-night home trial. The Siena Signature Memory Foam Mattress is a 10-inch, four-layer foam bed built around 2 inches of contouring memory foam, sold with a 180-night trial and a 10-year warranty. One is a luxury innerspring you choose in three firmnesses; the other is a simple foam mattress priced to move. This comparison lays out what each brand states about construction, feel, policies and price so you can pick the one that matches your body and your budget.

- 365-night home trial
- Free white-glove delivery and old-mattress removal
- Lifetime warranty
- Three comfort levels and two heights to choose from
Which mattress should you choose between the Saatva Classic and the Siena?
You should choose the Saatva Classic if you want an innerspring with a Euro pillow top, the ability to pick from three comfort levels, and full-service delivery with your old mattress taken away. You should choose the Siena Signature Memory Foam Mattress if you want a straightforward 10-inch foam bed with 2 inches of contouring memory foam and a price that starts well below the Saatva. The two products sit in different categories: one is a coil mattress with a luxury positioning, the other is a foam mattress built for value.
The decision comes down to three questions. Do you want coils or foam? Do you want to choose your firmness, or take the single feel a foam mattress gives? And do you want white-glove setup in your room, or a bed that ships free and arrives compressed?
Who is each mattress for?
The Saatva Classic suits sleepers who want a traditional innerspring feel with a plush top layer and who care about picking the right firmness for their sleep position. Saatva offers it as Plush Soft, rated 3 out of 10, for side sleepers and lighter-weight people; Luxury Firm, rated 5 to 7, described as the most popular level and suited to all sleep positions; and Firm, rated 8, for stomach sleepers, back sleepers who prefer a very firm surface, and heavier body types in the 250 to 300 pound range. It also comes in two heights, 11.5 inches and 14.5 inches, and in sizes from Twin through Split Cal King.
The Siena Signature Memory Foam Mattress suits sleepers who want a foam bed with a memory foam comfort layer and who would rather keep the budget low than choose among firmness options. Siena presents one configuration: a 10-inch, four-layer construction with 2 inches of contouring memory foam. The brand also offers a 12-inch Signature version with a five-layer construction, an extra comfort foam layer and single action cooling, for those who want a taller bed.
Buyers who want their old mattress removed during delivery should look at the Saatva side, since Siena’s page describes free shipping and returns rather than in-room setup. Buyers who prefer a bed that ships quickly in a box should look at the Siena side, which states that orders ship in 1 to 3 days.

How do the feels and support differ?
The Saatva Classic gives you a choice of feel, while the Siena gives you one. Saatva describes the Plush Soft as soft and cushiony with extra padding on top and a body-hugging feel that relieves pressure points at the hips and shoulders. The Luxury Firm is described as a medium firmness with a balance of cushioning and uplifting support, designed to replicate the feel of luxury hotel beds. The Firm is described as lying on top of the mattress rather than sinking in, with balanced resistance. All three levels sit under a 3-inch Euro pillow top that comes standard.
Saatva’s support story centers on its dual-coil design, made of triple-tempered recycled carbon steel coils, and on its patented Lumbar Zone Technology, which the brand says ensures healthy spinal alignment in any sleep position. The brand also notes the mattress is endorsed by the American Chiropractic Association. The Siena side of the comparison is simpler: four layers, 2 inches of contouring memory foam on top, and a design the brand describes as comfortable and supportive without breaking the bank.
For a sleeper choosing between the two feels, the practical difference is that the Saatva lets you match the mattress to how you sleep, while the Siena asks you to accept the feel its single foam construction provides. If you already know you want memory foam contouring, the Siena delivers exactly that. If you are unsure whether you want soft, medium or firm, the Saatva’s three levels give you the option to decide.
How do the materials and construction compare?
The Saatva Classic is built as an innerspring. Its cover is a soft, breathable blend that includes organic cotton, treated with Guardin botanical antimicrobial treatment that inhibits the growth of bacteria, mold and mildew. Beneath that sits the 3-inch Euro pillow top, then the dual-coil system of over 1,000 recycled carbon steel coils in full size and up, tempered three times for durability. Saatva states the foams are CertiPUR-US certified and the mattress is GREENGUARD Gold certified.
The Siena Signature Memory Foam Mattress is built as four layers, with 2 inches of contouring memory foam as the comfort layer. Siena describes the construction as pressure-relieving memory foam at a price that does not break the bank. The Saatva Classic page describes a dual-coil design with a 3″ Euro pillow top, while the Siena page describes a 10-inch, four-layer memory foam construction.
Which is better for people who sleep hot?
Saatva addresses heat on the Classic with two design choices it states plainly: a naturally breathable, hypoallergenic cover with organic cotton that sleeps cooler, and a dual-coil design that allows more airflow throughout to help disperse body heat. The Siena 10-inch Signature does not make a cooling claim on the page reviewed here. Siena does offer a 12-inch Signature upgrade that lists single action cooling among its features, for shoppers who want a cooling element in a foam bed.
If staying cool is a priority, the Saatva’s stated airflow design and breathable cover give you something concrete to weigh. If you want cooling in a foam mattress from this brand, the 12-inch Siena Signature is the version that names it.

What do the trials and warranties say?
Saatva gives every mattress a 365-night home trial, described as a pressure-free period with plenty of time to decide, and covers the Classic with a lifetime warranty for the original purchaser against defects in workmanship and materials under normal residential care and use. The warranty also includes a Fairness Replacement Option. Siena gives the Signature a 180-night home trial and a 10-year warranty, alongside free shipping and returns.
The gap is straightforward: twice the trial length and a warranty that runs for as long as you own the mattress on the Saatva side, against a shorter trial and a fixed-term warranty on the Siena side. Shoppers who like to take a full year to be sure should weigh that difference heavily.
How do the prices compare?
The Saatva Classic is listed at $2,229, with sizes ranging from Twin through Split Cal King and two height options. The Siena Signature Memory Foam Mattress is listed at $329 for a Queen, with the brand noting the mattress starts from $179. Siena also offers monthly payments at 0% APR financing. The price difference between the two is large, and it reflects the difference in category: a full-service innerspring with a pillow top against a foam mattress sold at a value price.
Shoppers should also factor in what comes with the price. The Saatva figure includes white-glove delivery, in-room setup and removal of the old mattress at no additional cost. The Siena figure includes free shipping and returns. Both brands run promotions on their pages, and those change often, so check the current price before you buy.
Who should not pick each mattress?
The Saatva Classic is not the right pick for a shopper whose budget comes first, since it is positioned as a luxury innerspring at a price well above the Siena. It is also not the pick for someone who specifically wants a memory foam feel, since the Classic is built as an innerspring with a Euro pillow top rather than a foam comfort layer. And it is not the pick for someone who wants a bed in a box that ships in a few days, since Saatva delivers it with white-glove service instead.
The Siena Signature Memory Foam Mattress is not the right pick for someone who wants to choose among firmness levels, since the 10-inch Signature comes in one configuration. It is not the pick for a shopper who wants a long trial, since Siena’s trial runs 180 nights against Saatva’s 365. It is also not the pick for someone who wants their old mattress carried out during delivery, since Siena describes free shipping and returns rather than in-room setup and removal. Finally, it is not the pick for a heavier sleeper who wants the Firm option Saatva rates for the 250 to 300 pound range, since Siena does not publish a firmness scale for the 10-inch Signature.
Which Saatva should you consider instead?
If you like the Saatva side of this comparison but want to look at other options, the brand’s lineup includes models aimed at specific sleep setups. Shoppers interested in a wall-bed arrangement can read about the Saatva Murphy bed, while those with a split head configuration can look at the Saatva split head option. Families furnishing a shared room can check the Saatva bunk and trundle youth page, and shoppers who want to protect a new mattress can read the Saatva mattress protector review.
On the Siena side, the brand offers more than the 10-inch Signature. The Siena Signature 12-inch memory foam adds a fifth layer and single action cooling, while the Siena Essential 8-inch hybrid and Siena Essential 6-inch foam cover shorter profiles for guest rooms and tighter budgets.
Verdict: the Saatva Classic is the pick for comfort choice and service, the Siena for budget.
If you want three firmness options, a dual-coil innerspring, a 365-night trial, a lifetime warranty and free white-glove delivery with old mattress removal, the Saatva Classic is the side of this comparison to buy. If you want a 10-inch memory foam mattress with 2 inches of contouring foam, a 180-night trial and a Queen listed at $329, the Siena Signature Memory Foam Mattress is the value pick. The Saatva costs more because it is a different category of mattress, not because one is a better version of the other.

Frequently asked questions
How do the firmness options differ between the two mattresses?
The Saatva Classic comes in three published comfort levels: Plush Soft at 3 out of 10, Luxury Firm at 5 to 7, and Firm at 8. The Siena Signature Memory Foam Mattress comes in a single configuration, a 10-inch four-layer build with 2 inches of contouring memory foam, and Siena does not publish a firmness scale for it. The practical difference is choice: one brand lets you match the mattress to your preferred feel, the other offers one feel per model.
What is the difference in height between the two mattresses?
The Saatva Classic is available at 11.5 inches or 14.5 inches, so you can match it to your sheets and frame preference. The Siena Signature Memory Foam Mattress stands 10 inches tall. Siena also sells a 12-inch Signature with a five-layer construction if you want a taller foam bed.
Which mattress has better edge support?
Saatva lists sturdy edge support as one of the five slides in the Classic’s construction carousel. Siena does not describe edge support for the 10-inch Signature on the page reviewed here. Shoppers who sit on the edge of the bed to put on shoes should weigh the Saatva’s stated edge support as a concrete detail.
How long can I try each mattress at home?
Saatva gives you 365 nights with every mattress, described as a pressure-free trial period. Siena gives you 180 nights with the Signature, alongside free shipping and returns. Both trials let you decide at home rather than in a showroom.
Do both mattresses come with a warranty?
Yes. Saatva covers the Classic with a lifetime warranty for the original purchaser against defects in workmanship and materials under normal residential care and use, and includes a Fairness Replacement Option. Siena covers the Signature with a 10-year warranty.
