I got this mattress for my daughter who was moving into her big girl bed! Easiest transition and most comfortable mattress - she is so happy! Now I need one for myself!

Does not expand to the listed depth of 12 inches. Depth is different depending where along the edge measurements are taken ranging from 4 inches to 8 inches.

Amazing mattress

Wonderful mattress

[This review was collected as part of a promotion.] This Bed is Super Comfy, Thick, and High-Quality! Exactly what I expect from a trusted brand like Serta! It arrived in a box and was ready to set up, very convenient that I did not even have to leave the house and it was shipped to my front door! Upon opening the box it only takes a minute or so to fully expand like magic! First thing I noticed was that it is a nice thickness at 12", much thicker than my previous mattress. It is plush, comfy and I had no difficulties adjusting to sleeping on the this new mattress, usually, it takes weeks for me to feel comfy. It conforms to your body and gives you a great nights rest! Very pleased with this hybrid mattress!

I got this mattress for my kindergartener daughter - she loves it! It's so plush and cozy, perfect mattress!

It's a basic mattress but doesn't cause any back pain so far. It came as described. Would recommend added a memory foam mattress topper on top.

I'm very happy about the firmness and comfort. I like a little give, and the medium firm is perfect.

My mother was astonished that a bed came vacuum sealed, both mattress and box spring. It is very comfy, thanks Serta.
