Our new mattress arrived on-time and nicely packaged. It took two of us to unpack it and place it on our guest bed. The compressed mattress reached its full size in less than 24 hours. The smell was strong for several days, and now after several weeks is very faint. It's not a problem. We own a Temperapedic, which we sleep on regularly and love. As a replacement mattress for our guest bed, we didn't want to spend as much as for a Temperapedic, and hoped that this would be a good substitute. It is, and we are very pleased with our purchase. It is somewhat softer than our classic Temperapedic, but I'm guessing that it's similar to the Temperapedic's new Cloud model. The cover is plush and very well constructed. Having only slept on the new mattress a few nights I can't speak for it's long term performance, but do find it very comfortable. I would recommend this mattress to anyone looking for a good memory foam bed.
