Thank you for viewing. [Recommended from an Expert's Perspective] Senoby Footrest, Desk Footrest, Supervised by a Chiropractor, for Telework, Footrest, Foot Pillow, Under Desk Footrest (Black) [Product Specifications] Length 255mm x Width 430mm x Height 103mm, lightweight design weighing 355g, uses high-resilience cushion with a density of 30d. The washable mesh cover prevents stuffiness and keeps it clean. The entire underside is non-slip, ensuring safe use on carpets and flooring. [Supports Correct Posture] The height of desks currently sold is 70cm-72cm. It is said that the correct posture is to align the height of the chair's armrests with the height of the desk. When the chair is adjusted to the height, people of smaller stature may have poor foot contact, compressing the blood flow in the thighs, leading to swelling and cold sensitivity. This footrest was developed to address this. [Supervised by a Chiropractor] In the production, we received advice from a chiropractor with a qualification as a judo therapist, a professional in skeletal structure, and created a footrest that is comfortable to use for long periods in terms of height, firmness, and angle. [Reversible Design with Adjustable Height] When you want to relax, using the inclined surface allows you to use it not only under the desk but also on the sofa or as a footrest in the car. When you want more height, turning it over provides a maximum height of 103mm. Brand new, unopened. (Slight damage to the package)
