Like other reviewers, we found that our new very expensive memory foam mattress provided good support but was too firm, not enough pressure point relief. Over the last several years we have tried many memory foam toppers on our memory foam mattress, from 2 to 4 thick, and from 3 lb density to 5 lb density. They all developed permanent indentations from use over time, and the typical hump in the middle of the bed. This problem has also been noted by other reviewers, and is apparently typical of memory foam toppers. Were not heavy people, but this topper has started to do the same thing after a couple of weeks (and it has a nasty smell which has still not gone away). It was perfectly comfortable, and would be good for a guest bedroom, but not for continuous use. A better choice: we read that the Dream Form Green Tea 2-inch Memory Foam Mattress Topper returns to its original size fast, the reviews were very good and it was priced right so we decided to give it a try. WOW! So far no indentations, no middle hump, the ventilation design is nice, and the light green tea scent is very pleasant (and almost disappears with time). Very comfortable, soft yet provides ample back support. And a perfect fit. We cant say enough good things about the Dream Form Green Tea 2-inch Memory Foam Mattress Topper, finally we have found perfect comfort with the perfect topper, get one, you wont be sorry! And as always, Overstock.com delivered quickly, its a great company! Note: if youre heavier than 150 lb you may want to consider the 3 or 4 thickness, which Overstock also carries.
