Hi Brenda, I had two-sided mattresses made, through Therapedic, 5 years ago. The ones we carry were engineered by me, personally, and are extremely high quality with no memory foam in any of them. We've delivered them all over the country for the last 5 years and without even a single complaint. If a high quality two-sided mattress is what you're after, the Cameo models are suitable for most people. The Medi-Coil models are designed to hold extra-ordinary body weight, with my heaviest customers topping 500 pounds....without sagging.

Therapedic licensees can produce their own line of two-sided products and the names and specs will be different depending upon the market. You need to get the complete specifications of the product from the retailer you visited. If they're not forthcoming, walk away.

Just because a product is two sided doesn't mean that it is more durable than a one sided product - it all comes down to componentry and construction. There were plenty of horrible, saggy two sided mattresses ten years ago when the industry was completely two sided.

Hopefully this is helpful.
