Very firm. Does hold body heat tho..get too warm. But over all we like it

Very comfortable mattress,

I am worried with the adjustable base, I am developing a soft spot in the middle.

Since our previous Sertas were good, we were glad to get these.

This is the best supportive mattress if you have back problems. I would wake in the morning and it would take about 30 minutes before I could stand up straight. Not with this bed! I get up and immediately I can stand up straight. Fantastic bed!!

[This review was collected as part of a promotion.] received the item a few months ago. it's quite heavy, queen size, the mattress is not very elastic, good for people with back pain, the fabric is breathable, comfortable

[This review was collected as part of a promotion.] Such a comfortable mattress! It's very durable and supportive, though it feels more like a medium than a firm in my opinion. It sleeps cool as well. Overall a great value!

[This review was collected as part of a promotion.] Wow. Im so excited to try this mattress! It is so comfort and supportive. Im having back problem and this firm mattress helps me tremendously. Highly recommend

[This review was collected as part of a promotion.] Amazing firm mattress! This mattress is very supportive while retaining a very high comfort level as you sleep. Extremely well made and durable. You definitely get your money's worth here!

So far / so good
