Liberator Wedge

The original 27-degree foam wedge with a removable microfiber cover.

  • Inclusive Fit
  • Easy to Clean

Positioning cushions are firm foam wedges and ramps that support hips, backs and knees. They are as useful for comfort and accessibility as for anything else, and they photograph like ordinary bedroom furniture.

Who may find it useful

  • · Couples who want more comfortable positioning
  • · Anyone with joint, back or mobility considerations

Who may prefer another category

  • · People short on storage space
  • · Those who want a smaller support cushion

The Liberator Wedge is the product the whole category copies: a firm high-density foam wedge at a 27-degree angle with a removable, washable microfiber cover. It is not cheap, and it is the one to buy if you buy one.
