Thermarest Air Mat Chair Regular Wide

This is an accessory that allows you to turn a Thermarest air mattress into a chair.

By folding and setting the air mattress, you can create a fluffy sofa.

I bought it about 3 years ago and used it twice, but I haven't had the chance to go camping recently, so it's been stored away.
The storage bag appears to have undergone hydrolysis during storage, but this does not affect its performance.

I am selling it as part of decluttering.
Please only bid if you understand that this is a used item.
