Description

11° Sitting Wedge Cushion

This angled seat wedge cushion is designed to create a slightly forward sitting position when placed on a chair. The 11° incline encourages an upright sitting posture while providing a supportive seating surface.

By tilting the seating position slightly forward, the cushion helps promote a more balanced sitting position during desk work, driving or everyday seating.

The lightweight wedge can be used on a variety of seating surfaces including office chairs, car seats, sofas and wheelchairs.

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?

UK delivery usually takes 2–4 calendar days from ordering, including processing and weekends. Delivery is free on orders of £39 or more, or £5 below that. Check the estimated delivery dates beside the price for this item.

Can I return it?

Contact us within 14 days of delivery, then send the item back within a further 14 days. You pay change-of-mind return postage; we cover return postage for faulty, damaged or incorrect items. See our refund policy for full conditions, including inspection rights, hygiene-seal exceptions and refund timings.

What is a seat wedge cushion?

A seat wedge cushion is designed with a slight forward angle to encourage an upright sitting position.

Where can the wedge cushion be used?

The cushion can be used on office chairs, car seats, sofas and other seating surfaces.

What material is the cushion made from?

The cushion is made from high density foam and includes a removable cover.

Can the cover be washed?

Yes. The cover can be removed and washed according to the care instructions.

What size should I choose?

The standard size fits most chairs, while the wide version provides additional seating width.

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.
