MEMORY FOAM BUTT CUSHION: This donut-shaped coccyx cushion is filled with premium memory foam and has a removable black velvet cover. The comfort cushion measures L41 x W33 x H6 cm and has an inner diameter of 16 x 9 cm. The cushion can support up to 120 kg. PORTABLE AND PRACTICAL: This coccyx cushion is lightweight and can therefore be used almost anywhere. When you sit, the weight is distributed without putting pressure on the perineum, lower back, or hips. This ergonomic seat cushion promotes good blood circulation and posture. EASY TO CLEAN: Each medical cushion comes with a removable black velvet cover that is machine washable at 30 degrees. It is important to keep it clean after prolonged use. This orthopedic coccyx cushion is sturdy and does not deform like inflatable cushions of the same shape. The non-slip coating makes it safe to use on most seats. CAN BE USED ALMOST ANYWHERE: Now you can sit comfortably wherever you are, at home, on the couch, or in the office. This hemorrhoid cushion is also suitable for the car, train, or plane, to relieve painful conditions around the coccyx, prostate, bedsores, or during pregnancy, or as an episiotomy cushion or sciatica cushion. Can also be used with a wheelchair and while sitting in bed.
