## Description

YJWAN Car Wedge Seat Cushion for Car Driver Seat Office Chair Wheelchairs Coccyx Support Tailbone Pain Relief Memory Foam Seat Cushion : desertcart.co.uk: Health & Personal Care

Review: Well worth the upgrade - resolved my aching bum - I'm relatively tall and heavy (17 stone/230lb/110kg and wide-ish backside), so simple/cheap cushions were little use. I sometimes sit for 2-4 hours constantly or only momentarily stand and my, otherwise excellent (and expensive), office chair's ergonomically shaped seat just doesn't have enough padding. With this cushion, I only get the same problem start around 8 hours. Fairly thick at the back, slightly slopes to a thinner front - but no sign of wear despite the chair seat underneath not being flat. Makes it comfier under your thighs on the edge of the seat (than if it was as thick at the front). The base is rubberised and pimpled, to avoid sliding around (no trouble when sitting) and the main cover material/mesh allows lots of flexing, so the material won't stretch out of shape or tear. Well stitched and constructed. I would have bought an even thicker version if available, but many reviewers are obviously lighter than me :) Has a fully adjustable elasticated strap that could stretch a chair's full width, or tighten to the stem of the back rest. Even comes in a smart zippable tube/bag you could reuse or for squeezing this small for travel.
Review: Firm , no movement, very wide - Straps onto seat well and doesn’t move , fairly comfortable if not a little firm . Very wide so may over lap

## Questions & Answers

**Q: I constantly have to adjust my sitting position as I feel I've slumped down will this stop this ?**
A: I suppose it depends on whether you like a higher driving position. I do and I don’t move about on this cushion. Important to sit as far back in the seat as is possible.

**Q: Is the cushion soft?**
A: As it is memory foam it forms the shape of whoever sits on it. First impression is that the cushion is firm but after sitting on it for a short while and the cushion has shaped itself around the sitter, the impression is that the cushion is soft but exceedingly comfortable and supportive. I highly recommend this cushion for driving and being a passenger. It is also useful in the home if a little bit of support and comfort is needed when sitting.

**Q: Does this add height?**
A: The original thickness of this is 7.5--8.5cm, and the height after adding the weight of the human body is 3--5cm. Hope it helps you.

**Q: Can this cause submarining in the event of a car crash?**
A: Hi, this cushion is held in place by an elasticated strap around the back of the car seat. So any forward movement of the cushion would presumably depend on the strength of the strap and the force of the forward movement. I think only the manufacturer of the cushion could advise on the strength of the strap and its ability to prevent any forward movement.

### ⭐⭐⭐⭐⭐ More than expected
*by T***A on 27 December 2023*

I am happily surprised with this cushion for my sports car where the seats dip back. I was getting a pain up the side of my leg on long distances, this cushion is perfectly shaped and stopped the pain. It is such a cheap remedy I will get another one for the passenger side. It is so comfortable to drive now.
