Review: great mattress for the price, reviews are right on!! - Amazed how great this mattress is! I ordered this on prime day after a long search for mattresses. It is for my daughter who is moving to another state. It arrived fast and was simple to take out, the day after it arrived. Left it laying flat for 3 days before putting it on the frame. It's amazing how great it looks. You'd never know it was rolled up tight in a box. It is being used on the Zinus metal frame. Comfortable mattress for the price. I slept well on it, no back pain and my quality of sleep is great. Very satisfied
Review: Great bed - I did lots of research between this and other mattresses. I did go up in height of mattress which I wasn’t expecting, but the 12” was $10 more than the 10”. I bought the twin 12” and was concerned it’d be firm but actually very soft. I’d say medium soft. However I think cuz it’s 12” it’s very tall it’s very squishy and moves a lot. I am an adult who’s heavier and everytime I change sleeping positions the bed shakes everywhere. But is still very comfy despite it being very shaky.

This mattress is pretty comfortable, it does have a few flaws like some lines and such that aren’t even.
