At 66 years old and bad joints I ditched the 3” memory foam and went with these for my jeep and 4runner. Way more comfortable, lighter and pack so much smaller.
Only suggestion is stop including the pump with the product. Sell a more powerful pump and it will make it twice as fast and easier to deflate and you can get the mattress significantly smaller with a better pump. I certainly did not need 2 pumps with the 2 mattress purchase and the rechargeable one is way too weak. I use an Airhead brand 12 volt pump (looks about the same but yellow) thats for water toy towables. Day and night different getting them put away.
