Thermarest chair/lounger. No longer even available on their website. I paid $65 new and hardly used it. This is for the wider thermarest mattress - 26 inch/ 66 centimetres. Provides back support when sitting/lounging in the campsite. I used to just leave my thermarest in it to sleep at night. $35 OBO I live in Lake Cowichan, though do occasionally come to Victoria.
