I've been looking for a booster seat and saw a couple of cheapo's for around £7-8. I then came across this one from Argos which looks a lot more comfier than the basic cheaper ones. Looking at this it seems to be £20+ everywhere else. On sale at £11.99 seems a great price for a quality booster seat :) 5* reviews.
