Hi, Aldi are selling those foam wedge things to go on your seat to help your back for about £3.99 and gym balls for £3.49. I have got a foam wedge and it's very helpful on computer chairs- I don't think I'll be getting a gym ball but they had two sizes- 65 and 75 cm. Aldi only have things in until they sell out so it's worth getting in soon if you want to catch either of these two items. Hope that's helpful to someone +++
Excellent - thats great hun - want to get a ball to sit on for now as it helps with my back ache if i rock back and forward
