After I figured out how to open the valves by rotating the sealing it's 'ball' joint it inflated easily and was very comfy and warm to sleep on even with 2 adults and a toddler. Took a lot of effort to roll up but definitely worth it for a good sleep
Overall I am very pleased with this camping mat. It is infinitely better than a blow up mattress as it doesn't deflate or bounce around when your partner moves. It is very comfortable. My only slight criticism is that the valves can be hard to open (they are a simple pull-push valve) and I worry that they might get broken, but only time will tell. I would prefer the screw type valves, but it's not a deal breaker and I would certainly recommend this product.
No longer do we have the faff of inflating air beds and the inevitable loss of air over night and reinflaton the next night. The Vango self in flare mate is hassle free and comfortable. Takes a little effort to pack away and squeeze out all the air, but that’s a fair trade off. Expensive, but you get what you pay for.
