My full review is below, complete with all of the details.
But if you’re pressed for time, here’s the abridged version…
The 10-inch Siena features three foam layers, capped with a polyester top cover and a shift-resistant bottom cover.
This diverges from the single- and dual-layer construction typically found among budget memory foam mattresses.
Plus, the top polyester cover no longer has polyethylene fibers to aid with moisture-wicking.
The core materials, however, remain the same.
Surprisingly, the Siena was a welcome reprieve from one of the hottest summers on record.
In terms of value, the Siena is a gem.
(It’s backed by a 10-year warranty, too).
These tweaks may give the Siena a more balanced bed feel than I experienced a year ago.
(The shift-resistant bottom cover is also polyester.)
With a total of five layers, it’s similar in build to its mid-range sibling, the Nectar.
(For the lowdown on that, read ourNectar Mattress review.)
At launch, it was already $200 off.
That discount eventually increased to $300, bringing the price of a queen to a mere $399.
Regardless, the Siena is quite a steal for a five-layer memory foam mattress.
That value becomes even sweeter with the inclusion of a 180-night trial period generous for a budget bed.
There’s also a 10-year warranty, which is comfortably within the industry average.
I’m a 5ft 4, 140lb side/front sleeper with a nagging lower back injury.
Siena rates its memory foam mattress at a 6.5 out of 10 on the firmness scale (medium-firm).
My panel and I felt much differently as we unanimously determined it was a much firmer bed.
Collectively, we rated it a 9 out of 10 on the firmness scale.
As someone who occasionally sleeps on their stomach, I found the Siena kept me well-aligned.
However, as a dominant side sleeper, I needed a week to properly break in the Siena.
I eventually settled into it and (fortunately) didn’t have any pain.
That wasn’t the case for one of the back sleepers in my group.
That matches what we human testers experienced.
So who will like the Siena?
It seems to be a match for back and stomach sleepers who prefer firmer support.
For a softer mattress at a similar price, consider the Allswell mattress.
you’re able to see how it compares with the Siena in ourSiena vs Allswell mattressshowdown.
Despite my tendency to occasionally overheat, I didn’t wake up sweaty once with the Siena.
The Sienas firmness potentially helps with its temperature control.Memory foam mattressesare prone to trapping heat with their enveloping sink.
The Siena mattress will keep most sleepers at a comfortable temperature.
(Note: The original Siena included polyethylene fibers woven into the cover for moisture-wicking.
Luckily, the Siena has superb edge support, which made my morning wake-ups much less painful.
The rest of my review panel said they felt secure when seated on the corner or along the side.
Minimal compression made it easy to push up.
For an objective look, I placed a 50lb weight along the perimeter.
The edges shouldn’t dip lower than the middle, so the Siena aces this portion of the test.
The six-month trial is a nice bonus, too.

Consider its mid-priced sibling, theNectar mattress, for a more typical memory foam experience.

Testers ranged in size from 5-foot-4 and 126lbs to 6-foot and 215lbs.
To objectively gauge the Siena’s performance, I conducted a series of standardized tests.
