I would post them on Freecycle - I can guarantee you someone will take them very happily!

I took mine to Fara and they took them.

Quick bit of advice; have finally taken the kids car seats out of the cellar to get rid of (they are 12 and 15!)
One is for babies in really good condition.. the other a booster seat for a 3 or 4 year old. I was going to take to Fara on Northcote Road but have heard charity shops won’t take them. Any idea of how to dispose of? Seems such a shame to take them to the dump (I hate throwing things away!)
