G'day Olivia,

You could use this with or without the mat although the mat gives it the structure it needs to be comfortable. It is a thin fabric so there wouldn't be any padding on the chair if a mattress wasn't used. 

A previous customer review said if you were exhausted at the end of the day and didn't feel like messing with the mat, the chair would still provide the back relief/reclining position. It just sort of squeezes you in since you don't have the mat as structural support.

G'day Zoe,

Thanks for getting in touch, I've just had a chat with our resident long walker Sam and she's used her air chair fairly extensively over a few years with both a comfort light insulated, and ether light insulated mat, and hasn't had any issues with wear and tear, so we think it shouldn't be an issue. Yes, the women's long will suit the Regular Air chair, as it is the same length as the Regular unisex model as you indicate.

G'day Edward,

Yes the Air Chair Regular is designed to fit all of the Sea to Summit small and regular self-inflating and air mats. So the Comfort Light Insulated Sleeping Mat Regular will be a good fit for this chair.
