  • So Comfortable and Cool

    I purchased this item with previous foam mattress experience and loved it. It is actually cooler. A lot of people complained about a smell - I didn't smell anything. The mattress does need time to expand. Though I had a delivery problem , Overstock was quick to address my concerns. Regular queen size sheets fit just fine.

    The mattress is comfortable. It does have an odor to it. I noticed but my husband did not. It did go away after about two weeks. Would buy again.

Would this mattress be considered a relatively firm mattress as far as Memory Foam mattresses go? Also, because of the Bio Foam would this not have as much of the smell that others have complained about with other Memory Foam mattresses? megslie on Jul 4, 2013

Answer This Question

Thank you for shopping with us megslie. This would be considered medium firmness. The smell that others report will leave usually within 3 days. I have a foam pad and it did take about 3 days before there was no odor. Have a great day. overstockcustomercare1 on Jul 11, 2013
