SKU: HAR SP24010 Category:


  • Medium firmness sitting wedge in our range.
  • Option of fixing strap to hold the wedge in place.
  • Coccyx relief option also available.
  • Size: 36x36x5cm (14x14x2″)
  • Fits on a car seat as long as you have a 30cm wide (left to right) level surface.

Slimline car seat cushion wedges help to level out your seat. Ideal if you are tall and there is minimal headroom in your car. Fantastic when you feel you need just a little added lift to ease muscle tension causing lower back pain.

These wedges come with the option to have a fixing strap if you would like to.  For most car seats because the bolsters hold the wedge in place a fixing strap isn't necessary.  If you have a flat sitting surface then they are definitely a good idea.

If you suffer with Coccyx pain, there are also a coccyx relief option where a section of the foam is cut away so that you have no pressure on this area whilst sitting. The cover is still square so that it hides the coccyx cut out section.

Size: 36x36x5cm (14x14x2")

This will fit into a car seat that is 30cm wide at the back or more.  By this we mean the level surface before your bolsters taper upwards at the edge of the seat.

Do You Need A Back Support Too?

Often a sitting wedge is complemented by a lumbar back support for a number of reasons.  It is important to note that as a sitting wedge will lift you slightly higher in your car seat you may then find that this will be necessary if your current lumbar support won't raise up to the new height of your lower back.  If so our range of back supports can be found by following this link.

  1. I needed this after I had a fall at work. It was amazing and took all the pressure off my coccyx. I love it so much, I’m going to continue to use it as it adds just a bit more comfort than the normal car seat.

    • Thank you for taking the time to reply Margaret. It’s great to hear that the cocyx wedge was so helpful for you whilst you were recovering. With the added benefit of extra comfort beyond.

  2. Brilliant

  3. Very helpful staff, and very efficient processing. And the 2 wedges I’ve bought for our cars are absolutely perfect. Really lovely that they have a 30 day trial period, as until you try them in situ you just never know if they will be suitable.

  4. I ve had the slimline wedge for 56 weeks and it s made a lot of difference in my lower back pain. The bucket seats are very uncomfortable and this wedge was just right to lift my hips and lower back to realign these areas. I also bought the duo car support for lumbar support. I think they were equally important in realigning hip lower back and lumbar area. I rode 2350 miles while on vacation and never had lower back hip or lumbar pain. Without these items I would never have been able to do this. The customer service was very helpful in choosing the items and the correct shipping method. I am very satisfied with these products and service and highly recommend them.

  5. I bought a couple of products from Sittingwell for my car as I found the sports style bucket seats very uncomfortable. I bought the dorsa back rest. If you have a car seat which is very soft and has little support this backrest definitely improves support and fits easily onto the chair.

    I also bought the slim wedge for the car as I was getting hip ache and this improved the pain a lot as it made the seats flatter. I would definitely suggest getting the slim wedge as originally I bought a thicker wedge from another company and although I am only 5 foot 4 it was making my head almost touch the ceiling.

    The customer service has been excellent. I rang the company originally for some advice on what products to buy and there was no pushy sales technique which was very refreshing.
