I've slept on the 25" wide version of this every night for three years. Still as good as new, but I decided I might like a slightly wider version. Arrived quickly, no odor at all, and I'm enjoying it just as I did its predecessor. I have used a comforter folded in half on both sizes to make it slightly softer, but doubt it's necessary. I might have tried a 6" thick version, but they're no longer available. I'm petite, but sleep better on these than on any other beds anywhere. Easy to visit ... I can bring my own bed!
