Description

Camp like royalty with the MondoKing 3D, an ultra-comfy 4.25-inch thick sleeping pad with a stretch knit fabric layer for resting better under the stars

Utilizing two one-way valves, one for inflation and one for deflation, the TwinLock valve system makes setting up and breaking camp a breeze

7.0 R-value insulates in the most extreme conditions using StrataCore construction that utilizes a continuous layer of thermal foam nestled between alternating ridges of air and foam

3D construction creates vertical sidewalls to maximize useable sleep surface and comfort

StrataCore construction allows the pad to easily compress and pack away to a compact 26x10.3 inches in included PFAS-free storage sack

For best performance, inflate your self-inflating pad with air by breath or included pump sack and leave the mattress fully inflated for 2-4 hours before your first use

Large size measures 77x25x4.25 inches, 26x10.3 inches rolled, and weighs 4.38 pounds; stuff sack/pump sack included; limited lifetime warranty; made in the USA

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $19 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Therm-a-Rest products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
