This is a Sea to Summit air mattress. It appears to be the Comfort Plus Mat model. It's a size S, approximately 168cm long. I purchased it 7-8 years ago, and used it 1-2 times a year. Includes stuff sack and repair kit (patches and air valve). I used a pump sack to inflate it, so I never inflated it by mouth. Please check the photos for the condition of the product. There are no noticeable stains or damage, but it is a used item that has been used outdoors, so please be aware of this before purchasing.
