I used this a few times a long time ago and it's been in the closet ever since. I checked it for this listing, and there are no air leaks or fabric deterioration, so I think it can be used normally. The valve opening has been disinfected with alcohol. The fabric is a bright yellow, so there are a few spots of dirt if you look closely, but it's at a level where you wouldn't notice unless you looked closely. However, this is a used item, so please understand this before purchasing. The following is the manufacturer's description: The THERMAREST LITE SEAT is a lightweight and portable cushion. LITE SEAT 28cm x 38cm This cushion inflates naturally when the valve is opened, and then you inflate it further by blowing into it a few times. It's convenient to carry because it packs down compactly. Please use it for outdoor activities, sports観戦, etc. - Brand: THERMAREST - Model Name: LITE SEAT - Country of Manufacture: USA - Color: Yellow Thank you for looking.
