My wife and I purchased this mattress about one month ago. We had a Serta memory foam mattress from Rooms to Go for about 4 years that was horrible. Anyway, we took a chance on this mattress and are glad that we did. We chose the Medium Firmness and it's really comfortable. Also, the smell that some reviewers have mentioned wasn't bad.
With that being said, here are some tips that will help you with the setup and a great night's sleep:
1. The king size mattress is approximately 100lbs, so I met the UPS guy at his truck and used a dolly to get it into our bedroom.
2. Then, I put it up onto the bed and carefully cut the wrapping.
3. We gave it 5 hours to expand.
4. Most importantly, standard deep-pocket sheets didn't fit. The fitted sheet kept popping off the corners of the bed. The bed is very thick. So, after trying several brands, we ordered the Tribeca Living 500 thread count Egyptian cotton extra deep pocket sheets on the Great Offer Stock website (model #500ECED4PSS). They fit up to a 23" mattress. They're very comfortable and I promise that you'll love them.
