Rated 5 out of 5 by from Amazing purchase I honestly can’t sleep on new mattresses because they mess my back up. But this mattress made me sleep like a baby throughout the night. I love this bed and def recommend it!

Rated 5 out of 5 by from Great mattress No regrets about purchasing this mattress! I've been sleeping on it for 2 weeks now and LOVE it. Every time I get out in the morning, I can't wait to get back in. It's the right amount of firmness for me - but if you like a firmer bed I would recommend going one level up.

Rated 4 out of 5 by from Very comfortable mattress We did a lot of research into bed-in-the-box mattresses. It came down to this one and the Brooklyn Bedding mattress. I thought this mattress had a more balanced feel, but it really was a toss-up.

Rated 4 out of 5 by from So far so good So... this review is based on one month of use. I'm not an bed expert as this is the first expensive bed I've purchased. The first two weeks I think it was still breaking in but I did feel that it was too firm but maybe I got used to it since then because it's been a great experience since then. Its great quality--it's one of those beds where you can jump on one side and you won't feel it on the other side. Regarding the purchasing experience--it was first class. From selection, explanation of competing brands, purchase, pick up and in packaging at home. It was really cool to see a bed fit in a box! Anyways I hope this review is useful for somebody. Would I recommend it? Yes.
