We ordered this just after Christmas, to replace the traditional spring mattress my wife and I had been sleeping on for the last 17 years. We ordered on a Saturday night, selecting the standard (cheapest) shipping option, and the mattress arrived on the following Tuesday afternoon. I was impressed at the speed of delivery. We unrolled it and laid it out in our garage to expand, because we didn?t have room inside the house. Because it was cold out there in December, it took a couple of days to really expand fully. After 3 days, we brought it inside and traded it for our old mattress. I can?t say that it really expanded to the full ten inches as advertised, but it was close in most parts. It didn?t seem important enough to quibble over. The corners still seemed a bit rounded/compressed, but it didn?t seem like a big deal. As some people have noted, it?s a couple inches wider than the full-size box spring we have, but that doesn?t seem to be an issue. The ?new memory foam smell? really wasn?t that bad, though I can imagine that someone else could be sensitive to it. We only noticed it occasionally, when getting into bed, when it would squish down a bit and force some air out. After two weeks, I didn?t even notice the smell anymore. It took a while to get used to. I?d never slept on a mattress like this before. The first week or so was an adjustment period for me. It WAS very comfortable to lay down on, but when you roll over or change positions in the middle of the night, it definitely responds differently than a regular spring and cushion mattress does. After two or three nights, I was worried that I might end up regretting the investment, but I knew that I?d need to adjust to a new way of sleeping and being supported, so I was ready to give it several weeks to be sure. Sure enough, I have adjusted to it very well. Ultimately, I don?t regret the purchase. I am pleased with it. It?s a fine mattress for the price, and if it lasts us a mere 5 years, it will have been worth it. I have no idea how well it compares to a full-blown ?Tempur-Pedic? mattress costing thousands of dollars, but it?s certainly good enough for us for now. We no longer wake up in the morning with sore backs, and it?s nice that your partner?s movement doesn?t jiggle the bed so much.
