  • This product is the perfect balance between a sitting wedge and a swiss/exercise ball.
  • Strengthen your back whilst you sit.  It’s a bit like Pilates whilst sitting…
  • Comes ready inflated just take it out of the box, sit on it and start experiencing the benefits.
  • Exercise poster & needle pump included.

The Sissel SitFit Plus inflatable air stability wobble cushion is a really versatile product. It is the perfect combination of a sitting wedge and a swiss ball. This inflatable cushion encourages good posture and can also help to alleviate upper back pain as you are constantly moving. Can it get any better when sitting becomes exercise in itself? Two jobs done in one!

Benefits of the SitFit Plus

There is an air pump (The needle is stored in the handle of the pump see video at the end of this description) so that you can inflate or deflate the SitFit Plus to adjust its level of stability. The more air the less stable it is (it arrives fully inflated), so that you can actively work your back and pelvic floor muscles whilst you sit.

You can also change the position of the SitFit Plus according to your needs. When the inflatable cushion is positioned with the rounded curve at the front then it is less stable, you will be using your muscles more.  This wobble cushion will be more stable when you place it in position with the flatter edge to the front.  This will give more support under your thighs for greater stability.  When you are first using this product or sitting for longer periods of time we recommend starting with the flatter edge at the front of your seat.

If This Is The First Time You Have Sat On An Inflatable Stability Cushion Read This Important Information

Because you are constantly working your muscles whilst you are using your SitFit Plus inflatable cushion you may need to gradually increase the length of time that you use it for. As your muscles get stronger you will able to tolerate longer periods of active sitting. If you have an existing back problem please seek expert advise to make sure that this is the right product for you so that you do not aggravate your current problem.

An exercise poster illustrating additional exercises you can do is included with your Sissel SitFit Plus.

We are serious about top quality and effective back care products we couldn't resist having a little bit if fun. So we created this video demonstrating the difference between the SitFit Plus and a Swiss Ball...Lorna never did this in rehearsals...

  1. the product has been really useful with my posture at my desk and the customer service from sittingwell was absolutely amazing!

    • Thank you for the review and I’m so pleased to hear the SitFit is helping. 🙂

  2. It was given to someone as a gift. They say it’s good. Very comfortable. Doing its job and easing back pain already!

  3. Great cushion, makes sitting for online meetings much more bearable. No more hip stiffness or discomfort, sometimes I switch things up and rest my feet on it, which is also excellent for keeping moving in a gentle way

  4. Arrived quickly, instructions are very clear and I have felt a benefit to my back and shoulders since using the Sissell SitFit Plus. Highly recommend especially if you don’t have adjustable desks or seats.
