Yellow cushion featuring a triangle support system. It hasn't been used much, so I think it's in good condition. (Please excuse any minor scuffs from use. There is a slight fraying as shown in photo 9, but I don't think it's very noticeable.) This is a set of two cushions: one for the buttocks and one for the lower back. The total retail price is 22,000 yen. A cushion for those who find their chairs at home or in the office too hard and can't concentrate... Just place "Keeps" on your chair, and your usual home or office will transform! ■Points■ 1. Upgrade your usual chair. Improves sitting comfort and maintains posture simultaneously. 2. Thick urethane material with excellent pressure distribution and breathability makes long hours of desk work comfortable. 3. Developed in a joint research project with Kanazawa University. Offering comfortable "sitting" from Nishikawa, who has been studying "sleep" scientifically. Plus, with the lower back cushion, you'll have complete support. Don't miss this opportunity! Thank you for looking.
