Our Top Pick: Saatva Classic

Best-in-class support, 365-night trial, lifetime warranty. Made in the USA.

Siena positions itself around one thing: price. A Queen for under $300. We tested it for 30 nights -- our standard minimum for any foam mattress -- to determine whether this is a legitimate budget option or a product that creates more problems than it solves.

Short answer: it is not good. But it has a specific use case where it makes sense, and we will be direct about what that is.

Construction

The Siena is a straightforward all-foam mattress. Quilted cover over a comfort foam layer (approximately 2 inches) over a base foam layer (approximately 6 inches). Total height: around 10 inches. No coils, no zoning, no gel infusion, no specialty materials. The foam densities are not published by Siena, which is itself a signal -- premium brands disclose foam specs because they are proud of them.

our top pick. After running the Saatva Classic through multiple sleep tests, it remains our benchmark in this category , long trial window, lifetime warranty, and direct-to-consumer pricing give it a structural advantage over most competitors.

The cover fabric feels acceptable but thin. Initial off-gassing was notable -- we aired it for 48 hours before testing began, which reduced but did not eliminate the chemical smell in the first week.

Feel and Support

The Siena has a medium feel out of the box -- approximately 5/10. After two weeks of use, it softened noticeably. By night 30, it had shifted toward a 4/10 feel with visible body impression forming in the primary sleep position.

Support is the core limitation. Without a coil system or high-density base foam, the Siena cannot maintain neutral spinal alignment for most adult body weights over time. Our 175 lb back sleeper noticed lower back discomfort starting around night 12. Our 145 lb side sleeper found it acceptable for the full 30 nights but noted the shoulder area compressing more than ideal by the end of testing.

Motion Isolation

Good, as expected from all-foam construction. No motion transfer was felt between two testers. This is the Siena's strongest performance category, though it is a low bar -- all foam mattresses isolate motion well.

Temperature

Below average. The foam traps heat without any cooling technology. Hot sleepers will be uncomfortable. We recorded 3-4 degrees F higher surface temperature on the Siena versus a comparable hybrid in the same conditions.

Durability Forecast

The body impressions forming at night 30 are a bad sign. With low-density foam and no coil support, meaningful degradation within 2-3 years is likely for regular adult use. Siena offers a 10-year warranty, but warranty claims require documenting impressions exceeding 0.75 inches -- by that point, the mattress has already been providing inadequate support for months.

Who Should Buy the Siena

  • Guest rooms used a few nights per month
  • Temporary situations: first apartment, between moves, dorm rooms
  • Replacement for a futon, air mattress, or floor sleeping

Who Should Not Buy the Siena

  • Anyone using it as a primary mattress for nightly sleep
  • Anyone with back pain, hip pain, or sleep issues
  • Sleepers over 180 lbs -- the foam will compress too quickly
  • Hot sleepers
Wait — before you commit to the Siena Mattress: we’d point you to the Saatva Classic first. Similar quality, but with a 365-night trial and up to $600 off right now.

Frequently Asked Questions

How much does the Siena mattress cost?

Siena mattresses typically retail between $249 and $349 for a Queen, with frequent sales below $300. This puts them in the lowest tier of the online mattress market, well below budget competitors like Zinus or Linenspa.

Is the Siena mattress good for back pain?

No. The Siena's single-layer foam construction does not provide adequate lumbar support for most adults. If you have chronic back pain, the Siena is not appropriate. You need a mattress with a dedicated support core -- either coils or high-density base foam -- to maintain spinal alignment.

How long does the Siena mattress last?

Based on material quality, expect meaningful softening and body impressions within 2-3 years for average-weight sleepers. At under $300, this may be acceptable for a guest room or temporary solution, but it is not a long-term primary mattress.

What is the Siena mattress made of?

The Siena uses an all-foam construction: a thin quilted cover, a comfort foam layer, and a base foam layer. There are no coils. Total height is approximately 10 inches. The foam densities are on the lower end of the spectrum, which explains both the price and the durability limitations.

Who should buy the Siena mattress?

The Siena is appropriate for guest rooms where the mattress is used infrequently, college dorm rooms as a temporary solution, and as a stepping stone if you are currently sleeping on a futon or the floor. It is not appropriate as a primary mattress for adults with any sleep or back concerns.

Bottom Line

If Siena fits your specific need (budget memory-foam mattress), it's a solid choice. For everyday sleep with maximum risk-reduction (365-night trial, lifetime warranty, free delivery), Saatva Classic is hard to beat.

OUR VERDICT

The Siena Mattress can absolutely work — but weigh the trial, warranty and return terms before paying full price. That’s where it loses to our top pick: for similar money, the Saatva Classic (luxury innerspring) gives you a full 365 nights to decide at home — several times the typical trial window.
