About this item

Product details

Very comfy

[This review was collected as part of a promotion.] I absolutely love this medium firm hybrid mattress! It is extremely comfortable and I struggle with finding the perfect mattress. It was very easy to unpack move. It is very heavy, however, and you definitely need two people to carry it. The parents is very nice and slick and I love the blue outline. The edges are very nice and you can tell the quality is very durable because of the stitching. Overall, I would highly recommend this mattress if you want to stay in budget, but also have a great product.

Alot of support l

[This review was collected as part of a promotion.] I really love this mattress. The medium firm feel is perfect because it gives me enough support without feeling too hard. I've actually noticed a big difference in how my back feels since sleeping on it, and I don't wake up with that same back pain and stiffness anymore. It's comfortable, supportive, and still has enough cushion to make it feel cozy. I also like that I don't feel like I'm sinking too far into the mattress. It was easy to set up and expanded nicely. For the price, I honestly think this mattress is a really good deal and I've been sleeping so much better on it.

Great Mattress

[This review was collected as part of a promotion.] Who knew that a bed out of a box could be so comfortable? I was not sure what to expect because I am very picky about my mattress mattress but this feels great. The full-size is perfect for our space and we have no complaints.
