Bests & Worsts Reviews from Amazon

I researched and researched memory foam mattresses. I read about foam densities, I read about response times. I read reviews and saw most were great; few were horrid. I compared and compared. This is what I got, all at the same time: 14" Lucid 5.3 lb firm cashmere 12" Lucid bamboo 13" SpaSensations Channel Quilted The 12" Lucid was like sleeping on dough. Initially quite cushy, but just didn't have the support. The 14" Lucid was fantastic. The 13" SpaSensation was a complete and utter failure - it didn't even expand properly and felt like I had just bought an old, regular bed with a hole in the middle. Our family of 4 tried all of them. It was quite the experiment! I love the Lucid 14" and am buying more of them for our family. We range from 130-250 lbs and are side/back/belly sleepers. We like firm support but a nice cushy feel. It's important to have a memory foam foundation, though. Either the Malouf Structures foundation or a wood box frame (no coils! just wood) work best. There you have it. :) UPDATE: 3.5 years later, the 12" softer one developed a hole (120-160lb person sleeping in it) and is no longer suitable. THIS firmer version, the 5.3 lb 14" mattress, is still going strong, with a variety of sized people sleeping on it over the years (120-250 lbs). It is a bit firmer than what I desired, but it's still holding up and the other, softer one is toast, with the hole in the middle causing back pain. I would buy this one again for the price and durability. UPDATE: Five years later: 14" Lucid 5.3 lb firm cashmere - still have this one on a Malouf foundation and it's made it's rounds with everyone in the family. Good. 12" Lucid bamboo - got rid of last year, as only a 100 lb person could sleep on it (great for a child, though?) 13" SpaSensations Channel Quilted - gone Also, the fitted mattress pad I used on these was a KEY factor in comfort and made ALL the difference in the world. I bought a super quilted, thick one at either Walmart or Target (I think it was around 40-60 bucks), and it turns it into a nice, cushy bed with firm support. I will add that five years later, I do not think the 5.3 lb 14" Lucid mattress is as firm as it once was. But it's still very sleepable.
