Worth the price

Recently moved and purchased this bed for my daughters room. I love that it came compressed in a small box easy to carry upstairs. It was easy to setup and once you open the box the mattress opened right up. The covering is washable so even if anything spills on it easy to wash and clean. It's the good medium mix between soft and firm. My daughter has enjoyed her new bed and it only took about 24 hours to get to the right firmness. Shipping was fast and worth the price.

I've never bought a bed in a box before so I was skeptical when it arrived. But after I unrolled it and let it sit for a minute, I was pleasantly surprised. Didn't have to fight to get it up the stairs. Just unwrapped and laid it out! This memory foam mattress is so comfortable. I'm a hot sleeper so the cooling feature is wonderful. It has a cover that is easy to remove to wash. I have dogs and cats, so this is a need to have!

Very pleased

Purchased this mattress for my daughters new loft bed. It comes in such a small package I was a little bit worried about the quality. It's memory foam so when you open it it does take a minute to puff up (insert says up to 72 hours) - the gray covering on the mattress is SUPER soft. I should have taken a pic before we put the sheets on but you can see how perfectly it fits our full size loft bed. It's the perfect density, super cozy and comfy. Highly recommend.
