Bought 2 twin XL for my King base because a king would not fit up my staircase. Mattress width a little too high but I can live with it. Replaced my sleep number bed that developed a leak after many years of service. First night - slept well.

the extra firm is very comfortable. it is hard enough to support my back without feeling like the floor, and it is just soft enough to sink into to sleep.

We enjoyed it the first night. Sometimes I wake up at 3am and have a sore hip, I only sleep on my left side.,so I have to get up and walk a little. I would give it a 4.5 star

Very comfortable. Recently had total hip replacement (x2). I needed better support. My other mattress only 3plus years old was horrible. I wish I came here first. Great service and no pressure

[This review was collected as part of a promotion.] Game changer hands down! My husband just had quadruple bypass and could not get comfortable on our bed, then this saving grace comes and he’s able to sleep our bed, forever greatful!

This is my third Beautyrest mattress. I can’t explain how pleased I am with my new Black Series Extra Firm. Slept well the first night! If you have serious back issues like myself, this is the mattress to buy! Loyal customer of Beautyrest!

Comfy and firm.

Great back support

Very supportive

Super firm, I love it.
