Abstract

The present invention is an improved Pilates chair having a seat top with an underside, a base that is wider than the seat top, a plurality of bracing members between the seat top and the base, a swingable lever having an upper end and a lower end disposed between the seat top and the base, the lower end being hingeably attached from the base, an adjusting block disposed slidably along the lever between the upper and lower ends thereof, means on the adjusting block for locking it in a position along the lever, and one or more elongated helical springs each having two ends, one of the ends being attached from the underside of the seat top, and the other end being attached from the adjusting block, whereby sliding said adjusting block along said lever, and locking it in a position therealong, will result in a greater or lesser extent of stretch being imparted to the at least one helical spring.
