Cool Sleep
Hot sleeper + back pain constant frustration until this topper. keeping me comfortable even in summer, the dual layers cradle my back without feeling too soft.

Comfortable
It really helps with the comfortable level of an old mattress that's in the spare room. It's easy to put on.

Decent.
This one has the egg carton shape to it. It works but not the best.

Best part of my bed. I love it.
I was a bit worried about getting only a 2 inch. Boy was I wrong. Just as good as the 4 inch topper I had before.

Mattress topper
I truly enjoy this mattress topper. not knowing if they would cause issue with my sleep due to slight sensory issues, but they aren't as apparent when laying as I'd thought they may be.

Not as thick as expected.
I bought this after having a 70 dollar one. Does not even seem 2 inches thick like they claim. Doesn't feel like memory foam at all.

The perfect topper for a side sleeper
Give this thing a few hours to stretch out after you open it, it fluffs up to the perfect mattress topper. It is a legit game changer if you're a side sleeper, Excellent value.

Comfortable
Great for my lower back The cooling effect isn't as cool as I thought it'd be but it certainly helps stop the sweat at night. Super easy to put on the bed
