I hate airbeds but turns out I just hated crap ones. Picked up an Outwell Dreamboat Double 7.5cm which is great. We no longer have a car so it's used as a spare bed.
EXPED - Megamats also worth a look but even spendier.
I use a 4 season multimat expedition in winter, a ultralight multimat in summer. Both foam, both lasted for years. Anything else is tomorrow’s landfill
Sleep mats. Talk to me.
I / We as a family HATE airbeds
