We purchased this mattress in a King size for our master suite after purchasing the same mattress in a Queen for our guest room. We had slept on the Queen mattress for a few nights to try it out and to make sure it was sufficient for any guests, and was so impressed we replaced our master suite mattress with a King. It is slightly firmer than I usually sleep on, but it is such a great product with a great price tag, you really can't go wrong with this mattress. Both my husband and I sleep great on it. Once opened from the box, it didn't have any kind of smell. We always let it rise for 48 hours just to be sure it fluffs out as much as possible. As I said, this is the second mattress we have purchased from this particular Wayfair line and have not been disappointed with our experience at all. Highly recommend.
