Dynasty Mattress RV 8" CoolBreeze Gel Memory Foam Mattress review

Dynasty Mattress is an online brand whose RV range comes in 8, 10 and 12-inch versions of its CoolBreeze gel memory foam mattress. The 8-inch model is sold in RV Queen, RV King, RV Short King and RV Full sizes, which makes it one of the few picks here for owners of RV king or short king beds. Dynasty rates it medium firm, says the foam is CertiPUR-US certified and lists free shipping, delivery in 1 to 3 days unless back ordered, and a lifetime warranty. The default RV Queen was $399.00, marked down from $640.00, when we checked. The product page is the weakest on this list: some copy on the 8-inch page refers to a 12-inch design, and the RV Queen size does not show its dimensions next to the picker. Confirm the exact length with Dynasty before ordering for a 74 or 75-inch short queen platform.
