Sanwa Supply Sanwa Direct Balance Chair Manufactured in 2022 With armrests and casters, it's convenient for easy movement. You can also remove the armrests and backrest to use it as a simple balance chair. Purchased to correct children's posture as it's adjustable. Adults can of course use it too. I bought two, and this one has hardly been used. I want to tidy up the room, so I'm selling it at a significantly reduced price. The seat surface is a smooth, soft leather-like material. I used it with a cover. I used covers sold on TEMU and Amazon, designed for rotating study chairs. Height adjustable, so it can be used by children to adults. My children are using it at home. Armrests and backrests can be removed. 2023 Sanwa Supply Inc. and Sanyo Transport, which operates e-supply, formed a partnership.
