4 inches and soft. Got it for my in-laws and they love it. No aching shoulder when they get up! Also it has a liner so it's easily washed

Bought this and enjoy it. Not over the top in cushioning and still has some firmness. Great for one person bed, unsure on multiples.

This is the best mattress topper I could have ever hoped for. It has helped me get such a good nights rest.

Bought these for the kids beds and now they don't toss and turn fir an hour bug instead fall fast asleep.

It is the greatest thing since sliced bread. Pillow top is a great name. No more back pain. Thanks so much.

Purchased first one last summer and was very happy with it. Purchased a second one for one of my son's that lives in NC. He loves it.

With this on the bed, i no longer wake up feeling like i went 12 rounds with Tyson or Ali. Great purchase!

I ordered for my dad. Very comfortable. Have been home about a month and so far no pressure sores. Would definitely recommend.

Bought one and tried it, sleep improved, back improved so bought two more to share the new improved sleep

Easy set up...expands nicely... in fact had to order small step stool to climb into bed (yes..I am only 5’2”)
