King Koil | Heavy Duty Mattress | Extended Life Mattress

Product Information

A common misconception is that the Extended Life XL91 King Size Mattress is only made for people who are overweight. The fact is the heavier building materials that makes up this heavy duty mattress and the optional foundation are longer lasting and much more resistant to excessive breakdown and the really deep body impressions associated with nearly any other brand of mattress made. This is the 2nd firmest mattress in the series of 6 beds.
