Mattress Insider 8.5" Latex RV Mattress review

Mattress Insider is a Colorado company that specializes in odd-size mattresses, and its 8.5-inch Latex RV Mattress is aimed squarely at owners whose factory bed does not match a standard size. The construction is 2 inches of blended latex, combining natural and synthetic latex, over 5.5 inches of plant-based high-density support foam, inside a 1-inch quilted organic cotton cover. The size menu includes both 60x74 and 60x75 short queens, a 60x80 queen and RV kings, and the 60x75, 60x80 and 72x80 sizes can be ordered with 10-inch radius corners at the foot, which many motorhome beds have. Anything else goes through the custom builder. The 365-day guarantee and 20-year warranty are the most generous terms on this list, though returns after 60 days must be shipped back with a $59 restocking fee. When we checked, the page quoted delivery in 3 to 5 weeks.
