OK. I don't write reviews. But I figured that, in the confusing, sometimes scam-ridden, world of mattresses, folks need to know about this one. 10" memory foam Foamex twin mattress. Here's the short version: product is exactly what it claims to be; it's firm but not excessively so; it's indistinguishable from the Tempurpedic Cloud; cost 1/4 of same; delivered in 4 days from Amazon with free shipping; wrapped in 4 layers of plastic, squashed to a fraction of it's open size; completely restored and 95% "de-odored" in 24 hours; slept on it the next night, about 36 hours after opening. Loved it. Couldn't be happier. Now, here's the long version: When I was a kid I had an ordinary foam mattress. I don't know whatever happened to it but I was left with the memory that I had really liked it. Because those things had been made with chlorofluorocarbons, they quit making them for many years and I could never find another one. Then a few years ago I started hearing about this "NASA-Developed" "space-age" visco-elastic stuff from Tempurpedic. Sounded like a lot of hype. Sent for a sample and information and, wow!, did THAT ever open the flood gates! Shades of AOL! I started receiving snail mail at least once per week and emails daily. Not the kind of marketing behavior that motivated me to buy ANYTHING from them! But I was, nevertheless, interested in the idea since I had liked the foam bed that I had so many years ago. So, about 6 months ago when it was time to replace our 10 year old conventional bed, I started doing a little bit more in-depth research: web, magazines, visiting mattress stores (including the trendy boutique Tempurpedic stores in malls), mattress stores, warehouses, everything, for 6 months. Here's what I found: Tempurpedic is the original, and, as such, sets the standard. Tempurpedic is absurdly overpriced and simply will not negotiate on price. If you don't care about price, you won't go wrong with them. Up to nearly 3 grand for a twin mattress (box foundation extra)! Wow again. (In all fairness, their "original" twin is down to $700) But I really did like the beds. I came to learn that mattresses have among the highest margins of most any home product. Approximately 60% or more. What that means is that for a bed that costs, for example, $1,000, it wholesaled for only $400, giving a $600 profit. Ever been to one of those little boutique mattress stores in a mall and wondered how they could possibly stay in business when only two or three folks per hour drift in and maybe only one of them actually buy? Well, there you go. At that rate, the store could make over $8,000 per 14 hour day with only a single sale per hour! Now you know why they're always on sale. Always! Found that most major manufacturers are now offering some version of a memory-foam bed. I also found that the mattress manufacturers will assign different names for their "warehouse" buyers for the same product to prevent accurate cost comparison. Really gets to be a problem. Discovered that there are only a handful of American manufacturers of the memory foam. Foamex is one. Many cheaper mattresses are manufactured in China and their recent manufacturing track history in general has been spotty at best. So look for American made. No guarantee, but the odds are better. The original Tempurpedic was a "slow-return" foam that took a couple of seconds to reform after pressure release, leaving "pockets" behind that you had to kind of climb up out of. Also, some had complained that they retained too much heat. They (or someone) came up with a "fast-return" foam with much better ventilation that they call the "Cloud," or "TempurCloud." A real improvement. And that's what you're getting with this Foamex mattress: 3 inches worth of fast-return memory-foam over a 7", relatively firm, conventional foam substrate (make no mistake, this "stacking" of memory foam over conventional foam is exactly what Tempurpedic, and everyone else, does - there are no 10" memory foam beds where all 10" are memory foam). And it's indistinguishable from the Tempurpedic Cloud," which is now their best seller. About $1,800 for a "TempurCloud" twin (11") mattress vs. $445 for the Foamex twin (10") mattress from Amazon, with free shipping from both. I have no idea if Foamex is the foam provider for Tempurpedic but it wouldn't surprise me. The bottom line here is your backside won't be able to tell the difference, but your wallet sure will. Oh yeah, about "foundations," what used to be "box-springs." These things are not your grandmother's actual boxes with real springs in them. They are now empty boxes, period. A sheet of plywood would do the same thing. Go for cheap (provided it's not so cheap that it'll collapse when you jump on it) and for the height (thickness) that you need to put the bed surface where you want it. In most cases, buying a cheap box from a discounter will be less than the one you'll buy with a "matched" set. Just check and be sure. The bottom line here is that there's no magic to a "box-spring" "foundation." It's a box. Period. (And in case you're wondering, my wife doesn't like the foam - it's really a love it or hate it kind of thing - so we now each have twins pushed together to equal a king. Works for us. We sleep together but we each have the mattresses we each like best.). So,there you have it: 6 months of sometimes painful research packed into this excessively long review. Glad I won't have to go through this process again for another 10 years. I need a nap.
