MyPosture Plus Chairs provide external postural, lumbar support and help maintain the natural curve of the spine. These chairs serve to offset the muscle fatigue that can lead to slouching and accommodate up to 100 lbs. 4 gray chairs included. Each chair features chrome, 10"H legs. MyPosture Plus Chairs coordinate perfectly with our new As We Grow Gray Blue Rectangular Adjustable Tables (as pictured). We suggest always allowing at least 7" between the chair seat and the tabletop when choosing the appropriate size table. Tables sold separately.
