I received it before the expected delivery date. It’s a good product; exactly what I was looking for a firm mattress. It was also easy to assemble. This is the second mattress I've bought. It has the perfect firmness, it's super comfortable and easy to unpack.

The mattress require 3 days to fully expand but so far it’s been 1 day and it already looks good. The mattress is firm and supportive. My kids say it’s the most comfortable bed in the house. The size fit the bed correctly, there are no weird smells, and the value for the money is worth it.

was easy to set up and is very comfortable, I have it paired with a foam mattress topper and it's pretty awesome but I played on it without it and it was really comfy, only through the pad on because I already had it. Can't even tell that it was rolled up in a box.

Best sleep I have gotten in years. Very firm, great value for the price. Make sure you are standing clear when opening the package bc wen it opens the force is enough to knock down a 35year old 200lb man

So comfortable if you like firm! Had this bed for almost a month now, best sleep I've gotten in months! We did the firm and its perfect for us.

Great budget option, nice thickness, the quality of the material is not bad. Need some time to set up. There was a slight new-material smell at first, but it faded quickly. Overall, a great value for the money!

Appears to be of good quality, have slept on it for 3 nights. Needed a firm mattress and didn’t think we could find a mattress in the box with springs, this one is very solid.

My husband and I highly recommend ESOON because they know how to treat their customers with courtesy and respect. The mattress we ordered is very comfortable and fits our needs and although our delivery was late, through NO FAULT of the seller, we were able to speak and get quick replies from ESOON-Direct in helping resolve issues and have a good purchase experience.
