I sleep on my sides and was losing circulation with my old mattress and also getting back pain. This mattress solves both of those problems and has improved my sleep immensely.

This is my second BRS900 medium mattress (Costco warranty). The first one I had it just 2 years and a hole was formed in the middle. It's been a week since the replacement (same one) and not satisfied.

[This review was collected as part of a promotion.] Have back problems and find this mattress a real asset. Makes sleeping easier and waking up refreshed.

Having set up the mattress, the wife and I tried lying on it and there was firm support, and it felt comfortable. I guess we will see how it goes after a while.

We appreciate how the mattress isolates motion of both sleepers. We added a memory foam mattress topper. The combination provided a very comfortable, restful sleep.

My partner and I bought this bed a month ago and have both been sleeping better. We don’t wake up with back pain anymore and it’s sooo nice to be pain free again. Thank you.

I have back problems which is why I require an extra firm mattress. In the past I have bought extra firm and I didn’t get what I purchased with this product. I can definitely say I have had the best sleep ever!

Had this mattress for a week now and I like it so far. I don't like mattresses with lots of memory foam and there doesn't seem to be any in this one. Plus it's firm, like I wanted.

Very comfortable

Very firm & gret price.
