The Siena Memory Foam Mattress proves that you get what you pay for. $399 for a Queen will get you solid support and optimal motion isolation, but it's not enough to afford proper edge support or cooling systems.
Siena falls under Resident Home, the sleep portfolio that also includes Nectar and DreamCloud. These beds are already budget-friendly, but Siena slashes prices still further. You'll never have to pay more than $1,000 for a Siena mattress, even for a California King.
As an H&G sleep expert, I'm part of the search to find the world's best mattress. The Siena Memory Foam Mattress won't be knocking our reigning champion off its top spot any time soon, but it's still one of the best budget-friendly beds on the market. If you're looking for an affordable mattress for a dorm room or a guest room, then you've come to the right place.
Siena Memory Foam Mattress review
I tested the Siena Memory Foam Mattress for a few months in the middle of last year, as we moved from spring into summer. I can confirm that this mattress is comfortable and supportive (at least in the center) and boasts excellent motion isolation, though the edge support and heat retention leave a little to be desired. When you consider its performance against its price, it's still one of the best memory foam mattresses on the market.
Siena Memory Foam Mattress Specs
Who would the Siena Memory Foam Mattress suit?
- Buyers on a budget: even at full price, the Siena Memory Foam Mattress is one of the most budget-friendly beds on the market. You get 10 inches of thick foam for just $799. More often than not, you'll find this bed listed for less in the mattress sales: I rarely see it selling for more than $399 for a Queen. That's just $199 for a Twin, and even a California King bed goes for $999.
- All sleep styles: the Siena Memory Foam Mattress is designed to suit all sleep positions. It's got just enough give to cushion your neck and shoulders, but sufficient support to lift and lengthen your spine.
- Couples: the Siena Memory Foam Mattress features minimal motion transfer. I'll explain more about that in a minute, but suffice to say it's good news for light sleepers and anyone who shares a bed with a pet or partner: you shouldn't feel their tossing and turning in the night.
What is the Siena Memory Foam Mattress like to sleep on?
- Comfort and support: as a back sleeper, I need a mattress to support my spine and stop my neck and shoulders from sinking too far into the bed. Since my old mattress had started to sag, I immediately noticed a difference with the Siena Memory Foam Mattress. I could comfortably lie in bed to sleep and recline to watch TV or scroll through social media.
- Cooling: as a hot sleeper, who prefers to sleep with sheets and blankets, I need my mattress to keep me cool. I haven't had the best luck with memory foam, which tends to trap heat and go soft in warm weather. That's why I was so pleased to discover that the Siena Memory Foam Mattress is actually a gel memory foam mattress, designed to dissipate heat and wick moisture. I tested this bed through the spring into the start of summer and found it kept my temperature regulated. Still, if you suffer from night sweats or hot flashes, I suggest you pair your bed with a set of the best cooling sheets.
- Weight bearing: here at Homes & Gardens, we appreciate anecdotal evidence, but we're all about data. I wanted to conduct an experiment to measure the weight bearing capacity of the Siena Memory Foam Mattress. So, I took an 8-pound medicine ball and placed it in the middle of the mattress, where it barely made a dent. This is proof of the firm feel of the Siena Memory Foam Mattress, which stops the sinking feeling you get from poor quality memory foam. In practice, this meant that I felt well supported on the Siena Memory Foam Mattress, no matter how I lay on the bed.
- Motion isolation: memory foam is designed to absorb movement, so it's no surprise that the Siena Memory Foam mattress excelled in our motion isolation test. I filled a glass with water and asked my friend to jump around the bed. The closer she got to the glass, the more it started to wobble, but it never spilled a drop of water. When we lay down on the bed, I couldn't feel it when she tossed and turned on the other side of the bed. My cat jumps on my bed every morning and every evening for feeding reminders and cuddles, and I don't even feel it when she lands on the mattress.
- Edge support: your average memory foam mattress has imperfect edge support, since the soft squishiness of the center extends around the sides. The Siena Memory Foam Mattress is no exception. When sitting on the edge of the bed to put on lotion, I always felt the need to scoot back in case I slid off. If you're looking for a memory foam mattress with solid edge support, I recommend the Emma Original Mattress.
- Sleep trial: the Siena Memory Foam Mattress comes with a 180-night mattress sleep trial. That should be plenty of time to test your bed through several seasons and keep a close eye on its thermoregulation.
- Warranty: the Siena Memory Foam Mattress comes with a 10-year mattress warranty that covers all the usual manufacturing defects. That might not sound quite as impressive as a lifetime warranty, but it's much more realistic, especially when you consider that your average memory foam mattress will only last you six to eight years.
How does the Siena Memory Foam Mattress rate online?
Out of 2,584 verified customer reviews, the Siena Memory Foam Mattress boasts 1,793 five-star ratings. That works out to around 70%, which is exactly the same rating as I gave in this review. Happy customers agree with me that the Siena Memory Foam Mattress offers contouring comfort and pressure relief. Almost everybody mentions the incredible value of the Siena Memory Foam Mattress.
There are quite a few more mixed reviews, most of which concern the firmness of the mattress. This doesn't surprise me, since firmness is so subjective: what feels comfortable for one sleeper could feel hard as a rock for another. If you find that the Siena Memory Foam Mattress feels too firm, you could always pair it with the best mattress topper. A few inches of plush foam could totally transform the feel of your bed, and you don't need to spend much more than another $100.
Should I buy the Siena Memory Foam Mattress?
The Siena Memory Foam Mattress is a budget-friendly bed with a medium-firm feel to support all sleep positions. Sure, it isn't as breathable as an hybrid mattress, nor as durable or sustainable as a latex bed. But, for my money, the Siena Memory Foam Mattress is still the best affordable mattress on the market.
How we test mattresses
We put a lot of thought into how we test mattresses. Our expert testers sleep on beds for months, if not years, to monitor their performance over time, with a special focus on thermoregulation throughout the seasons. We assess each mattress against the same criteria: comfort; support; cooling properties; motion isolation; edge support; and weight bearing capacity.
Some of our tests are simpler and more subjective. The best way to experience the comfort of a mattress is to sleep on it and see how we feel. Other tests are more scientific. To measure the motion isolation of a mattress, we fill a glass with water, set it in the center of the bed, and apply pressure all around it. The more the glass moves, and the more water spills, the less suitable the mattress for light sleepers and bed sharers. We also consider all the practicalities of buying a bed, including mattress sleep trials and warranties.
Where possible, we compare our findings against verified customer reviews to show a range of experience with the same mattress. Then we bring it all back to the price to help you determine value for money.
