Retail Price: ¥12,100 I recently purchased this to reduce the strain on my lower back due to a lot of desk work, but another cushion suits me better, so I'm selling this while it's still new. I only used it for a short time to try it out, so I'm listing it as "like new." Supports comfortable seating even for long hours. Recommended for long hours of desk work, office chairs, and telework. ■Size Approx. Width 35 x Depth 35 x Thickness 4cm No smokers or pets. #Tempur #DeskWork #LowerBackPain #SeatCushion #ChairMat #Cushion
