I purchased this mattress 4 months ago and have no problems with it. I received it in a box and took it out of the box and waited a half an hour to take form. The mattress was comfortable from day one and is still comfortable. There is no sagging, creases, lumps, or holes. The mattress holds its shape and is guaranteed for 5 years. I definitely would purchase this mattress again because of the excellent quality, value for the money, and ease up transport in it and setting it up. I would recommend this mattress to my friends, family, and colleagues because of the value, quality, and ease of setting up. I use this mattress as my primary mattress and bed.
