I never imagined purchasing a mattress online. Normally, you go to a brick-and-mortar store, awkwardly lie on a bed on which the cleanliness is questionable while other customers wander around staring at you. At the suggestion of our Physician, we tried it. This is the best, most comfortable, most fabulous mattress we have ever owned. It showed up on the porch in a box. That's right. A box. Miraculously inflated before our very eyes on the bedframe. We haven't been the same since. Really.....buy the mattress. Sell something to buy the mattress. It is worth every dollar. It is an indescribable comfort level that you will not get with a standard mattress/box spring combo. The mattress is exactly as advertised in every way. Cool, soft yet firm, supportive and comfortable. BUY THE MATTRESS!
