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.
