Orthex Symbia 2.5" Ergonomic Seat Cushion
If you spend long hours sitting, your lower back knows it. The Orthex Symbia 2.5" posture cushion is designed to position your hips slightly above your knees, which supports the natural lumbar curve. It works on any chair, car seat, or office seat.
What It Does
- Pelvic alignment: Positions hips slightly above knees to restore the natural lumbar curve
- Pressure redistribution: Distributes your body weight evenly across the buttocks and hamstrings
- Comfort without compromise: Gel-infused memory foam on top, high-resilience Velva foam underneath for lasting support
- Stays cool: Coconut-fibre knit cover is breathable
Construction
Two-layer foam system. The top layer is gel-infused viscoelastic memory foam for pressure relief. The support layer is Velva high-resilience polyurethane foam, which maintains its shape over years of daily use.
Specs
- Dimensions: 18" x 15" x 2.5"

- Cover: Breathable coconut-polyester knit, machine washable in cold water
- Warranty: 5-year manufacturer warranty against defects

Who It's For
