[This review was collected as part of a promotion.] Sleeps as advertised! Extra firm supports the body really well, without being "hard". Temperature wise, feels really great while sleeping and no hot flashes. Really could not be a better combination with memory foam and supporting foam!

[This review was collected as part of a promotion.] We are in total love with this mattress. The iComfort Q10 Extra Firm is pure perfection to sleep on. The gentlemen who delivered and set it up were the nicest. I know going up a narrow staircase was not easy. This mattress has phenomenal total body support. My husband and I truly wake up so well rested. Our previous mattress did not come close to the perfection that is this mattress. I am happy to wake up, and start my day , we truly have the best sleep ever. Love love love this mattress. Our Australian Shepherd loves it too. Ultimate comfort and sleeping pleasure. Excellent delivery and a superior mattress. Highly recommend.

[This review was collected as part of a promotion.] This mattress is amazing!!! It is super firm yet very comfortable! It supports my husband and I very well! I sleep on my side, so most mattresses aren't comfortable, but this one is amazing! It keeps me cool as well! I usually have severe lower back pain, but since sleeping on this mattress, it has really helped with the pain!

[This review was collected as part of a promotion.] I received the Serta iComfortECO Q10 Extra Firm mattress & so glad I did. I suffer from back problems & this mattress is perfect for me. Very comfortable , I can actually get a good nights sleep. Made with great quality materials. I highly recommend this great mattress.

[This review was collected as part of a promotion.] We have never slept so good. Mattress is smooth with no lumps, buttons or holes even after weeks of use. There is no movement on my side of the mattress when my partner gets in and out of bed, or when tossing and turning. We ill purchase another one of these and recommend to friends.

[This review was collected as part of a promotion.] Daughter has acute back problems, hoping this mattress would give some relief, she said it was amazing! Actually allows her to get a good night sleep with out tossing and turning all night, which helps her husband sleep as well! Good Night!

[This review was collected as part of a promotion.] I have a bad back - it is a problem I have had for a long time. When I can find a mattress that supports my back with a good firm feel I know I have come upon a product that I will want all the time. This Serta mattress is just the one I want. It is comfortable, easy to get on the bed and gives me a great sleep without a lot of pain in the morning when waking up. Thank you Serta.

[This review was collected as part of a promotion.] Excellent Product!! Very comfortable to sleep on. Not hot like some other mattress. Normal sheets fit very well. Excellent sleep quality and extremely comfortable. This will put an end to sleep back pain!!

[This review was collected as part of a promotion.] The mattress is so comfortable. It is nice and firm but also forms to your body but not so much where it sags. I have back pain so this mattress was a great equal of firmness and comfort. Its hard enough not to make my body sink into it but also not so hard that I feel like I'm laying on stone floor.

[This review was collected as part of a promotion.] I was so excited to get this mattress and it didn't disappoint! It was easy to unpack and set into place on top of my box spring. I didn't have any trouble adjusting to the new mattress. I chose the firm one and I believe it is a low profile height.
