These pads provide a wider area of support than the classic knee pads and as such have a variety of uses in your practice. They offer a firm support for sitting when the table is too low, with a wider base of support than the regular knee pads. They are just the right size for kneeling over the table lessons. They are also useful for putting between the legs when the client lies on the side. The foam is durable and you can expect them to last well even with a lot of use.
