Finding a good mattress without spending a fortune can feel impossible. But the Siena Memory Foam Mattress has changed that for a lot of people. We tested it to see if it actually delivers what it promises—cooler sleep, lasting support, and real comfort for less than $500.
You get a 10-inch mattress with memory foam for pressure relief and coils for support. It’s wrapped in a breathable cover, and the price? Surprisingly low. Here’s everything you need to know before you buy.
Trying Out the Siena Memory Foam Mattress
This mattress mixes memory foam and coils in a way that works. You feel supported, but you still get that soft, cozy feel from the foam. It’s a nice balance for people who don’t want to feel like they’re sinking in.
At the top, there’s a gel memory foam layer that keeps things cool. Below that, wrapped coils help with support and reduce motion when someone moves. The fabric cover also helps with airflow.
It’s available in three firmness levels—Plush, Medium, and Firm—so you can pick what feels best. Whether you sleep on your back, side, or stomach, there’s a version made for you.
And the best part? It starts at just $299. You even get a 180-night trial and a 10-year warranty.
A Quick Siena Mattress Review: What We Found
This mattress feels like it was built with real people in mind. You can choose the feel you like, and the materials are clean and certified.
- The Firm version supports your back and stomach well.
- Medium is the go-to if you change positions a lot.
- Plush is soft and best for side sleepers who need cushion for shoulders and hips.
The coils also give the mattress a bounce without losing support, which helps if you move at night.
Let’s Talk About Memory Foam Mattresses Like This One
There are a lot of memory foam mattresses, but many trap heat or feel too soft. Siena’s gel foam keeps it cooler. It also cradles your pressure points without sagging.
You’ll still get the classic memory foam comfort, but with better airflow and more support underneath. The coils make it easier to get in and out of bed, too.

Sleep Experience You’ll Actually Notice
From night one, it feels different than an all-foam mattress. The foam keeps you comfortable, while the coils give you that solid lift.
- Hot sleeper? You’ll feel the difference with the gel foam.
- Sharing your bed? Movement is isolated, so you won’t feel every toss and turn.
- Need edge support? This one holds strong even when you sit on the side.
- Like to move around? You won’t get stuck. It’s easy to switch positions.
Just give it a couple of weeks to break in. Like any mattress, it needs time to adjust to your body.
Setup and Care Made Simple
It ships in a box and takes about 10 minutes to set up. Just unbox, unroll, and give it time to expand. It may have a light scent at first—that goes away in a day or two.
You can use it on most bed frames including platforms, slats, and adjustable bases. Just don’t flip it—rotate it every few months instead.
Want it to last longer? Add a waterproof mattress protector. It keeps things clean and helps with warranty coverage.
