Sensus is a Foamex product. (I'd done quite a bit of research and (through some prying phone conversations with Foamex) found out that they once supplied Tempurpedic.) They are THE memory-foam authority. (Let that sink in for a minute.) If Tempurpedic chose this company to make their products, it must be top-quality.

I own this particular topper and I can say it is everything you want a memory-foam product to be; resilient, durable, firm, supportive, responsive and COMFORTABLE! I promise, you won't be disappointed with it.

I've also "done the math" and figured out the actual density. My Sensus topper has a density of 5.3 pounds per cubic foot; the exact density of the Tempurpedic topper. So there's no skimping on density, here. I reiterate, the up-front price is tiny compared to the long-term value. Expect 5 years of flawless performance from this dense foam. You may even get ~10 years out of it, depending on use.

It was a great mattress topper while it lasted. However, in less than five years of ownership I noticed the topper lost a considerable amount of firmness. It became too soft to sleep on except for the edges and I found myself waking up less refreshed. It's like trying to sleep on a 'V' shaped mattress.

I contacted the manufacturer, Foamex, twice via email but they never responded. Finally I called and was told they won't service the mattress; redirecting me back to the seller who has since gone out of business. I have no experience with this seller, however I would suggest anyone considering purchasing a Sensus brand viscoelastic mattress or topper be aware that you will likely have problems before the ten-year warranty has expired. Plus, even if you find a seller who doesn't turn a warranty claim into a hassle, you will find they are rather expensive to repackage and ship. I will not purchase another Sensus or Reflex brand product.

I have bought sensus memory foam pads for every bed I have had to sleep on in the last few years, and I love them. [...] My first Sensus mattress topper was a 4 inch version from a bedding website and that did cost me over 400 and I still felt that it was worth it, but i would have given up the inch and just gotten the 3 inch version on overstock if I knew it would cost less than half that. The shipping costs on overstock are almost nonexistant as well. Maybe the person who said it wore out after 5 years wouldn't be so upset if he/she only paid 170. That would work out to only $34/year.
