Removable and washable seat cover The washable hammock seat cushion features a zipper for easy removal of the cover. The freestanding inner liner has been improved to wrap the cotton thread, so the cotton thread will not loosen when removing the cover. 15 cm thick inner padding The egg chair cushion uses PP cotton padding with good load bearing. The 15 cm extra thick inner padding is soft and comfortable, making you feel less rigid than a swing chair or basket chair. It effectively reduces hip pinch, provides good rebound, lowers hip pressure, relaxes the hips, and offers a softer, more comfortable seating experience. With armrests The outdoor hammock chair cushion has two armrests to help you relax your arms and enjoy your time more fully. Anti-slip straps The cushion with a one-piece backrest includes anti-slip straps. They can be securely attached to the hammock and will not move. The concave-convex thickened design helps the cushion fit the body curve better, increasing comfort and reducing stress. Use scenarios - Relaxing on a porch, patio, or garden hammock while reading or sipping a drink. - Lounging on a balcony or during camping trips for a comfortable, supportive seat. - Poolside or outdoor lounging where a stable, cushioned seating surface is desired.
