Siena Signature 10" Memory Foam review

The Siena Signature 10" Memory Foam is one of the cheapest beds in our dataset. It has 2" of contouring memory foam over stability and base foam, plus a 180-night trial. Siena labels it Medium Firm, but Tom's Guide tested it as firm, 8 out of 10, the firmest score here. This Siena mattress review finds it a strong budget pick for back and stomach sleepers who want firm, flat support. It's a poor fit for most side sleepers, who need more cushioning at the shoulders.

Siena feel and firmness

An 8 out of 10 is solidly firm. You get a thin layer of memory foam softness and then a dense, flat base. The gap between Siena's "Medium Firm" label and the tested 8/10 matters. If you've been shopping by label, this will feel firmer than you expect.

With only 2" of memory foam over stability and base foam, there isn't much between you and the firm core. That's the main reason the bed tests firmer than its label. The simple build also keeps the price low.

Best (and worst) sleeping positions

Stomach sleepers are the best match, because firm support stops the hips from sagging and arching the lower back. Back sleepers over about 130 lbs also do well. Side sleepers are the clear miss. Tom's Guide found pressure relief lacking at the shoulders and hips, and an 8/10 surface will feel hard for most side sleepers. Very light back sleepers may also find it unforgiving.

Cooling, motion and edges

Motion isolation is a 5, so a partner's movement is barely noticeable. Edges start out at 4, but Tom's Guide noticed reduced edge support after about 10 months of use, so expect the perimeter to soften. Cooling is a 3, typical for all-foam. The firm surface helps a little because you don't sink in.

Price, trial and warranty

Siena shows a "total value" of about $742 for a queen, which looks inflated by bundled extras. The usual price is around $329. Tom's Guide lists an MSRP of $399 and has seen sales near $294. You get a 180-night trial and a 10-year warranty, solid terms for a bed this cheap.

Ignore the "total value" figure when you compare. What matters is the price you'll actually pay, which has ranged from about $294 to $329. At that price, even a few years of good use is a fair return.

How it compares

The Zinus Green Tea costs about the same but is much softer (5.5/10), so it's the better budget pick for side sleepers. The Nectar Classic is also firm (7.5/10) and costs more, but has 5/5 edges, a 365-night trial and a lifetime warranty. If you want coils at a budget price, the Allswell Hybrid adds bounce.
