by a Certified Chiropractor and Produced in an ISO 9001 50D Foam Car Lumbar Support Cushion Can be Used for Back or Comfort with Washable 6cm 3D

["Fit design" that wraps around the waist] The shape follows the line of your back and waist, supporting a stable sitting posture. We aimed for a comfortable sitting experience with reduced "wobbling" even when sitting for long periods of time. [2-in-1, 2-way function] As a cushion, it softens the seating surface, and as a backrest, it supports a comfortable fit from the back. You can use it according to the situation. [High-density 50D foam] We use foam that strikes a balance between sinking and rebound. The shape of the foam supports the entire surface, preventing body pressure from being concentrated in one area, resulting in a comfortable sitting experience. [Consideration for how body pressure is distributed] In-house evaluations comparing it with general memory foam cushions have confirmed that it tends to distribute pressure more easily (compared to sitting under the same conditions). However, individual sensations may vary. [Air flow: Ventilated structure to prevent stuffiness] The breathable mesh allows heat and moisture to escape easily, keeping you cool and comfortable even for long periods of time. Easy to use in any season. Grip tech: Non-slip surface for a secure grip. Designed to prevent slippage when getting on and off or braking. [Easy to clean and quick-drying] The cover is removable and easy to wash, and is made of a quick-drying material. It is easy to keep clean. *We recommend using a laundry net. [Quality Control] Produced in an ISO9001 certified factory, with basic performance and finish designed for everyday use. [Easy to use in a wide range of situations] Not only in the car, but also in office chairs, gaming chairs, and chairs at home. Makes it easy to adjust your everyday sitting time comfortably. [Caution] This product is not a medical device. It is not intended to improve, treat, or prevent symptoms, and sensitivity varies from person to person. Take appropriate breaks when driving for long periods of time, and discontinue use if you experience any discomfort. ・["Fit design" that wraps around the waist] The shape follows the lines of your back and waist, supporting a stable sitting posture.
