I bought this mattress for my daughter & it was fully expanded in about 4 hours(it has actually expanded to 11"). It had a faint smell at first but that went away within a few hours. It is nice and comfy & a much better value than the 10" mattress, that comes with 2 bonus pillows, that I bought for myself. I would recommend that you spend the extra $20 on this one... Only issue I have is that no warranty/receipt was included with any of the packing.
- Would you recommend this to a friend? Yes
