BootySprout is a one size fits most. It can comfortably be used within the height range of 140 cm - 195 cm.
The height of BootySprout's foam back support is 35.5 cm, measured from the wood foot rest. This is an ideal height for hip thrusting. Most flat benches are 41 - 46 cm in height and are too high for most users when performing barbell hip thrusts.
