phiten Premium Back Support Cushion for Cars - Lumbar Cushion I purchased this at Autobacs, but it didn't suit my back, so I'm selling it. I've only used it once, so it's practically new! I chose it for its easy-to-care-for leather finish. 【High-Quality Materials】 Made with luxurious synthetic leather, combining durability and comfort. 【Ergonomic Design】 Ergonomically shaped for a design that reduces fatigue even during long drives. 【Versatile】 Applicable not only to car seats but also to office chairs and home sofas.
