Transform Your Driving Position & Office Seating Posture
Whether you are facing long commutes behind the wheel or sitting at a desk for 8+ hours a day, traditional seats often force your spine into a slumped, uncomfortable position. Our Orthopaedic 8-Degree Seat Wedge is specifically engineered with an ergonomic slope that gently tilts your pelvis forward, automatically guiding your spine into its natural, upright 'S' curve.
Recommended by chiropractors and posture specialists, this simple 8-degree angle opens up your hip flexors and encourages "active sitting"—helping relieve lower lumbar pressure, tailbone sensitivity, and general driving fatigue.
Designed for Life on the Move (Strap & Handle Included):
Unlike standard cushions that slide around on car seats or office chairs, our premium wedge comes complete with an adjustable, removable fixing strap to lock it securely in place. Plus, the fitted velour cover features a discrete built-in carrying handle and lightweight foam design, making it effortless to carry between your car, office desk, dining chair, or wheelchair!
Provides Targeted Comfort & Seating Support For:
- Improving daily sitting posture and spinal alignment
- Relieving lower lumbar pressure during long car drives and commutes
- Pelvic and hip joint seating support
- Office workers, drivers, and wheelchair users
- General seating discomfort and stiffness from extended sitting
Premium Product Features & Specifications:
- Ergonomic 8-Degree Slope: The industry-standard angle recommended for optimal posture without feeling like you are sliding forward.
- High-Density UK Foam: Crafted from superior, resilient support foam that maintains its structure without flattening out over time.
- Washable Velour Cover: Includes a luxurious zipped cover complete with a carrying handle and securing strap.
- British Craftsmanship: Expertly handmade in Devon, United Kingdom.
- Quality Guaranteed: Backed by a full 2-Year Guarantee for complete peace of mind.

Frequently Asked Questions
Frequently Asked Questions
What is a sitting wedge?
A seat cushion with a forward tilt that encourages a more upright sitting position on office chairs, car seats and home seating. Some models include a rear coccyx cut-out — check the product title for this listing. It is not a bed wedge.
How is this different from a bed wedge?
A bed wedge elevates your upper body or legs on the mattress. This sitting wedge goes on a chair. The angle is an 8° or 11° sitting tilt, not a sleep incline, and it is a comfort support rather than a reflux treatment.
Will it stay on the chair?
Whether this listing includes a strap or carry handle is shown on the product images and details for this model — do not assume every sitting wedge has both.
When will it arrive?
Typical delivery after dispatch is 2–4 days to the United Kingdom. Free over £39; under that, delivery is £5.00. Courier: Royal Mail, Evri or Yodel. Handling is 1–2 business days after a 12:00 PM (UK) cut-off.
Can I return it?
Unused items in original packaging can be returned within 14 days of delivery. You pay return postage unless the item is faulty — then we refund or replace at no charge. No restocking fee. Refunds are processed within 10 business days. Start the return from your account or the contact page.
What is a sitting wedge cushion?
A sitting wedge cushion is designed with a slight forward angle to encourage an upright sitting position.
Why is the cushion angled?
The angled design tilts the seating position slightly forward, which many people find more comfortable during extended sitting.
Where can the wedge cushion be used?
The cushion can be used on office chairs, car seats, sofas and other seating surfaces.
Can the cover be washed?
Yes. The zipped cover can be removed and washed according to the care instructions.
Where is the cushion made?
The cushion is handmade in the United Kingdom.
What degree wedge is best for posture?
8-11 degree wedges are optimal for pelvic tilt correction. The 8° is gentler for beginners; 11° provides more aggressive posture correction for chronic slouchers. Start lower and gradually increase angle as your body adapts.
Seat Wedge Cushion for Car & Office Chair with Adjustable Strap
A stable incline that does not need rebuilding
The firm wedge creates a consistent raised surface, unlike stacked pillows that can compress, separate or move during use.
Broad support area
The wide surface distributes support instead of concentrating it at one edge.
Multi-position use
Use the wedge for supported rest in bed or on another stable surface.
