Kamaboko-shaped lumbar support cushion Sold at a home center as a lumbar support cushion for a floor chair. Can also be attached to ordinary chairs with backrests and office chairs using the included rubber straps. Black, mesh, with Velcro straps. - Color: Black - Material: Mesh - Straps: Yes - Shape: Semicylindrical F-SCD01 Approximately 430mm x approximately 180mm x approximately 100mm Purchased at DMC Used for about 2 weeks as a back support for an office chair due to lower back pain. The difference in usage period compared to other cushions is that my back and lower back were comfortable, so I used it for a long time. It's easy to attach, just by attaching it to the waist area of the chair's backrest, but surprisingly, my back and lower back felt better. Black mesh matches office chairs. Lightweight material makes it easy to carry. Thank you for viewing. This year, I made my shocking lower back pain debut. I am listing several items as a result of trial and error. It's about whether they suit you or not, So please rest assured that the items are not bad. #BolsterCushion #BackSupportCushion #LowerBackPain #OfficeChair #LumbarSupport #SupportCushion #PriceReduction
