Orthex Symbia 2.5" Posture Cushion

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 fix the root cause: a tilted pelvis that flattens your lumbar curve and puts pressure on your discs. 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, reducing joint stress
• Comfort without compromise: Gel-infused memory foam on top, high-resilience Velva foam underneath for lasting support
• Stays cool: Coconut-fibre knit cover is antibacterial, hypoallergenic, and 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"
• Supported regions: Buttocks and hamstrings
• Cover: Breathable coconut-polyester knit, machine washable in cold water
• Warranty: 5-year manufacturer warranty against defects
• Care: Foam spot-clean only; cover machine wash cold, lay flat to dry

Who It's For

Works well for anyone who sits for extended periods at a desk, in a vehicle, or watching TV. Particularly helpful for people managing lower back tension, tailbone discomfort, or early-stage posture issues. Not a replacement for medical treatment, but a practical support tool for daily use.
