I have only had this mattress for 5 days, I am giving a 5 star because so far the description, size and delivery times were accurate, actually it arrived 1 week sooner than expected but the wayfair notifications kept me updated so I knew exactly when arrival would be. We slept on it after 10 hours because it seemed to be fully expanded and we excited to try it.  So far no complaints, it is comfortable but I guess time will tell.
