Struggling to decide between 4 and 5 stars.  Bed came quickly and set up easily. It had no odor and is very comfortable. My wife loves it, although it is a tad softer than I would prefer. More importantly, my back hasn't hurt since getting it, unlike the old mattress I replaced. Overall, really solid purchase based on owning for a short period. Especially because the price was reasonable, I went with 5 stars. It seems a similar product would have been 3-4 times the cost at a local retailer.
