If you are wanting a decent Highchair then grab the Safety 1st Timba Wooden Highchair from Amazon. Not only does it score 4.3 stars but it's only £37.04 with FREE delivery included. This particular Highchair sells for around £70 elsewhere, so this is a bargain.
The Safety 1st Timba Wooden Highchair can transform to accommodate your child from 6 months old to 9/10 years (maximum weight of 30kg)
It features a removable three-point safety harness, safety bar, food tray and the seat and footrest are adjustable.
Considering this can change from a Highchair into a Junior Chair, I can't help but think this is incredible value for money at £37.
