Original Seat Cushion with LiquiCell Technology (18W x 17 x 2)

Key Features

• ADVANCED LIQUICELL TECHNOLOGY : Ergo21’s exclusive LiquiCell membranes reduce skin shear, improve circulation, and relieve pressure from your tailbone, hips, thighs, and lower back. Unlike gel cushions or memory foam, this fluid-based system supports healthy blood flow and prevents numbness or tingling. Great for sciatica, coccyx pain, or long sitting periods at work, in the car, or at home.
• ERGONOMIC DESIGN FOR POSTURE, BACK & HIP SUPPORT: Shaped to align naturally with your spine and pelvic region, this cushion helps reduce muscle strain and relieve lower back pain. Supports correct posture and improves comfort whether you're driving, working at a desk, or watching TV.
• CAR, TRUCK & OFFICE READY : Use this seat cushion everywhere! On office chairs, car seats, desk chairs, mobility scooters, recliners, airplanes, RVs, gaming chairs, or stadium seats. Lightweight and portable, it’s perfect for commuting or travel. Designed to reduce road vibration while driving and relieve fatigue on long rides.
• COOL, BREATHABLE MICRO-STRETCH COVER + NON-SLIP BASE : Top layer made of premium micro-stretch fabric promotes airflow to keep you cool and dry, unlike hot gel cushions or synthetic covers. LiquiCell tech prevents hotspots and skin irritation by minimizing friction. Bottom base is waterproof and non-slip, staying securely in place on any surface.
• PORTABLE, LIGHTWEIGHT & INSTANTLY COMFORTABLE: No straps, no setup! Just place it down and feel the comfort. Weighs under 1 lb. and easily moves between seats at home, work, or on the go. Great for travel, airplane seats, extended drives, or everyday office use. Designed for soft, balanced support across all seating types, this cushion supports users up to 200 lbs.
• BETTER THAN GEL OR MEMORY FOAM: Unlike other seat cushions that go flat or trap heat, Ergo21 uses patented LiquiCell technology for superior comfort and pressure relief. Helps manage tailbone pain, herniated discs, spinal stress, and poor circulation. Given faith by professionals and real users for durable, lasting support.
