Very pleased.
First, a tip. Use first aid scissors with a blunt tip on the bottom portion to remove the right plastic bag and avoid ripping the cloth cover. It would be a god idea if that were a product recommendation from the manufacturer to avoid damage. I'm certain I would have torn the cover otherwise.
Now, the review: I wanted a Tempur-pedicure Cloud Elite, but couldn't justify 3k dollars for a mattress. Decided to search through Great Offer Stock and buy one that sounded similar to the way it felt, with soft give on top, and firm support beneath. This is definitely similar, though not the same. If you want a Temp Cloud and are looking for a substitute, this one is satisfying. The other mattress I considered was a Serta Savant III, and it reminds me very much of that mattress, but a fraction of the cost. I have degenerative disc disease, and my back doesn't hurt after sleeping. I'' only on day three, and will update later.
If I rated this mattress against the others, it would be a 4 out of five, the serta a 4.5 out of five, and the Tempur a 5 out of five.
It loses a point against the Tempur for not having quite the double feeling of hard and soft at the same time, it does have that, but not as pronounced, and both the Serta and Tempur had better reinforced sides and a better cover. I think the serta and this mattress probably felt almost the same.
