I purchased the 8in mattress. This bed was a great purchase for our son’s bunk bed. It’s comfortable enough for an adult to sleep on (according to my 200lb, 6ft tall hubby). The mattress holds its shape well and the factory smell was totally gone after a couple of days airing out. The mattress was within an inch of its full height before a full hour of it resting on the bed frame (see photo); It reached full height across the entire mattress sometime within the first 24 hours. It came with a tool to cut the plastic off of the mattress, so there was no risk of cutting the foam. The listing claims that it is free of fiberglass - which was important for us. This is a great budget-friendly option! I highly recommend!

This mattress is a great value for the money. It was time to get our son a bigger bed but we needed to be economical and tried this one in a 8" full size. It was delivered fairly quick and vacuum sealed in the box. The customer service was great and they also provided information in the box of how to best open and let the mattress rise along with an opener to help safely open it. It had no smell upon opening and took about 48-72 hours to fully rise. We did need to loosen the inner covering in the corners a bit to help in rising. We also loved that while it was doing it's thing, we were able to take off and wash the outer cover. It was so easy to get on and off and is super soft. Once we were able to put it on the bed, my son fell in love with how comfortable it was. As an adult sitting or laying on it to test it out, it gave good support and was comfortable. It was also the perfect depth and fit for out bed. We have now had a few weeks of our son choosing his bed over the couch for his restful nights and we would definitely use this company again.

I'm using this mattress for 6 months. It's horrible! The mattress is pressed in the place where the person is lying. You're lying like you're in a deep hole, you can't sleep and your back hurts a lot in the morning. I bought this mattress in the hope that it would be hard enough. But it fails. Don't buy this mattress, you'll get big problems with your spine

I did order this mattress in a 10 inch, but I received an 8 inch. Cost more to send it back than I paid for it. Otherwise, it's comfortable.

Very lightweight product. Very easy to move around. I let it sit for 48 hrs before first use. It is firm yet soft. It is very comfortable and great quality. There was a slight smell when first opened but I have a very sensitive nose. No one else could smell it unless they put their face right against the mattress after first opened. Easy to follow instructions and great packaging. My daughter loves it and am planning to replace two more of my kids mattresses with this one.

El colchon es bastante bueno, lo único que no me quedo conforme fue que pague por uno de 8" y me llego uno de 6"

Got a queen size mattress. It’s really soft and firm. Slept like a baby. No more back aches. Took about 24hours to get to its original form but I let it sit for 48hours. I do suggest removing the mattress cover so that all the corners can inflate properly and evenly. I also flipped the mattress over to level it out. After 48 hours you can zip the cover back on.
