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.

The mattress is truly a firm mattress! Style is slightly different from the BRS900nthat that I bought about 5 years ago for my mother, but it's still a great mattress.

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!

I bought one of these for my guest bedroom and all the guests like it. The extra firm is actually not that firm, it's just right. I like that it's also not a super thick mattress that is so hard to put sheets on and super heavy.

[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.

I bought these mattresses because I had a lot of back pain and very poor sleep quality and after just 2 days of using them the pain disappeared and I sleep great and feel really rested! LOVE THEM

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.

These are great products, I have used nothing but Beautyrest for the last 25 years. I will never buy any other mattress due to the quality and comfort of their products.

Very comfortable

Firm and supportive.
