I sit 9 hours a day at my desk. The 4-wing seat cushion eliminated my tailbone ache completely. Essential for remote workers.
Overview
Transform any chair into an orthopedic oasis with the ComfoVa Ergonomic Hollow 4-Wing Memory Foam Seat Cushion. Designed with a patented 4-wing contoured curve and an oversized central relief cavity, this cushion isolates pressure from your tailbone, hips, and thighs to support healthy posture during long sitting hours.
Key Features & Benefits:
- 4 Major Ergonomic Zones: (1) Contoured hip cradle, (2) Dual leg-hug channels, (3) Ischial tuberosity pressure dispersion, and (4) Central hollow ventilation core.
- Targeted Coccyx & Tailbone Relief: Central cut-out suspends your tailbone in the air, instantly relieving spinal compression, hemorrhoid discomfort, and sciatic nerve tension.
- Promotes Upright Posture: Gently tilts pelvis forward to maintain the natural lumbar curve and reduce slump fatigue.
- Ultra-High-Density Memory Foam: Medical-grade memory foam provides plush support that resists flattening under body weight.
- Breathable Honeycomb Mesh Cover: Removable zippered cover with non-slip silicone bottom keeps the cushion firmly anchored on office chairs, car seats, or wheelchairs.

Will it fit my chair?
It measures 45 × 40 cm. Measure the flat part of your seat to check it fits comfortably.
How much height does it add?
It is 10 cm at its thickest point, so you may want to lower your chair a little.
Which way round does it go?
The cut-out goes at the back, under your tailbone, with the two leg channels at the front.
Will it slide around?
The silicone base grips the seat underneath, so it stays in place as you move.
Can I use it in the car?
Yes, it works on car seats too. It raises you slightly, so check your seat and mirror positions before you drive.
Why does it feel firmer when it's cold?
Memory foam responds to warmth. In a cold room or car it can feel firmer at first, and it softens as it warms up.
How do I wash it?
Unzip the cover and machine wash it following the care label. Keep the foam itself out of the washing machine.
What about delivery and returns?
Delivery is free across South Africa and usually takes 2–5 business days. Every ComfoVa comes with a 30-day comfort trial: if it isn't right for you, contact us within 30 days of delivery and we will arrange the return. See our returns policy.
