The MondoKing 3D with its 10cm 3D construction delivers maximum comfort and versatility. Vertical sidewalls provides 20% more usable sleep space. 

Thermarest says:

Updated: Sleep like camp royalty with our thickest luxury mattress. Are you always on the lookout for something bigger and better? Your ship has arrived with the MondoKing 3D. Simply put, the MondoKing™ 3D is the biggest Therm-a-Rest® mattress ever. Vertical sidewalls create 20% more usable sleep surface so you have room to sleep like starfish. Dual valves allow compressible foam core to expand and inflate quickly when unpacked. Stuff sack included.

Thermarest's MondoKing 3D Self Inflating Mat really does prove that bigger is better. Yes it has a large pack size but what do you expect from Thermarest's biggest mattress. It's obviously not the type of mat you would take in your pack backpacking but it's perfect for basecamp or car campers who want to sleep as well as they would have at home.

The foam core means that it is a self inflating mat so there's no need for pumps and batteries, just unroll it, open both the valves (there are 2 to increase the inflation speed) and leave it to do its thing.

The MondoKing 3D now uses a new fabric which is more comfortable and stretchier.
