I own a Tempurpedic mattress and wanted a foam bed for my 3 year old son's new full size bed without the higher price. I had to add a waterproof mattress cover for obvious reasons, but with or without it the mattress is very comfortable and my son has slept through the night every night thus far. Since we didn't use a boxspring we cut plywood to size for underneath the mattress and over the bed slats to prevent the foam from pushing through the slats when my son stands on his bed. The mattress was shipped quickly and after opening it, we were able to use it the same evening. There was little smell, but it dissipated quickly.
