The product is great. Delivers exceptional comfort and great night's sleep. However, in my effort to make the switch from split King to regular King, I have encountered exceptionally poor customer service at the corporate level, not the store level and sales person level. They have been great. But their hands are tied due to operational deficiencies at the corporate level. By the time I get the replacement mattress, at least two months will have elapsed since I requested the change. It may end up being longer.
