This is an awesome mattress I'll Quote Brad from trailrecon.
The most important thing to any roof top tent is the mattress. I'll second that. A good night slep starts with the SELF-INFLATING AIRCORE MATTRESS.
Solid upgrade to an already amazing tent!
The self inflating air-mattress is high quality and a much better mattress than what shipped with the Evolution (V1). Very impressed and grateful that FreeSpirit offer an upgrade discount to folks who purchased Evolution (V1). This is the mattress that should have launched Evolution.
Thanks FreeSpirit.
Double check the seams after you let it rise. I had a few areas in mine where the seam had holes and one area in the seam where it bubbled up. Their customer service was excellent in getting a replacement out! Just be sure that it holds air. It comes with a patch for the usual rips and pin holes. It would be great if they also included seam glue just incase this happens after warranty.
