Hi, The reason given is correct. The prediction of flattening out...not so much.

Agreed with Peter. The layers shifted, and the mattress is likely ruined.

I would demand an inspection to be done by this company. Due to it sitting on its side for so long, the glue has failed and the mattress is defective. Tell them to come look at it. Also, review the warranty for the mattress and see what it says about defects.

Good luck

It may be easily fixed. Try grabbing the fabric and foam padding where the bubbles are and lifting. Most likely the layers of foam have gotten stuck on fabric or another layer of foam. Once you lift, try and shake wave the material to get the bubble to disperse. We had this happen to one of the custom mattresses we built and delivered about 3 hours away. I sent my staff out with another custom size mattress in case I was wrong and sure enough the driver got there and shook waved the top layer of foam as I described above and the layers laid flat after that. What a hassle! Don't worry about it ripping anything.

Michael is right. You will have to grip the fabric and the foam underneath, pull it up, and move it outward to try and even the top. You should call for a replacement. That is not something that should have been left in your home.
