I have a new, still in the plastic wrap, Thermarest NeoAir Xtherm air mattress. The size is Regular (72"). I bought one for myself and a friend, but he ended up not wanting it. It is too late to return it so it is up for grabs.
Retails for $190. Asking $180 OBO. Yours for $165 + Free shipping! Email/PM me if you are interested. Check it out at REI.
