Ergonomic seat cushion in 100% memory foam – U-shaped design for tailbone and hip relief. High-quality memory foam: The cushion is made of 100% pure memory foam that molds to the body's curves using your own body heat. The ergonomic U-shaped indentation provides superior comfort, relieves the tailbone and reduces pressure on the hips when sitting for long periods. Comfortable and practical: The non-slip rubber base keeps the cushion in place even when you move. The removable and machine-washable cover with zipper is easy to clean, and the integrated handle makes the cushion easy to carry. Versatile use: Suitable for all types of chairs – perfect for office chairs, car seats, airplane seats, gaming chairs, bleachers or wheelchairs. A practical choice for work, travel, sporting events or the elderly. Safe material: All parts are certified safe and harmless to health, completely free of additives. Memory foam recovers quickly and returns to its original shape after each use, and can also be used to provide extra seating height. Perfect gift idea: Suitable for all ages and environments – home, office, bedroom, kitchen or student accommodation. An excellent birthday or Christmas gift for family, friends, colleagues, grandparents or young people.
