The seat can be as high as around 15 inches off the ground and as low as 11.8 inches. The legs can easily be turned to raise and lower the seats and they even mark off the height for you so you don’t have to struggle with guessing to make sure all the legs are the same length. Depending on what you’re doing, height can make all the difference in your comfort depending on whether you’re looking to bounce or stay in to eat. One unique thing I love that you’re not going to find in cheaper chairs with a similar design is that this one is height-adjustable. Or one person can sit on the stool and the other lay on the floor for more comfortable oral sex. That takes some of the strain off your back and knees. With your partner lying under the stool, you can bounce on them with the support of the stretchy seat straps. This Positioning Chair from Moonight is extremely versatile with dozens of positions made possible and more comfortable with this little stool.
