Great mattress. Fills & deflates quickly & easily. Very comfortable. My husband & I used it as a king sized bed (in our tent) & our sheets fit well. Keep in mind that the air within the mattress will assume the ambient air temperature so, if the nights are chilly, the bed will be, too. Take extra bedding, blankets, sleeping bags, etc, to put on the mattress - otherwise you will freeze! Great product & great price. Overstock kindly matched the price advertised elsewhere - their customer service was superb.
