Mamas & Papas Baby Snug seat (basically Bumbo with tray) in Green £29.25 at Tesco.

I prefer this to the bumbo because it comes with removable tray and most importantly has the insert which you can take out when the baby is bigger.

from description :
'The Mamas & Papas green baby snug is a unique 2 stage seat that helps your baby to sit and allows you to sit down. This 2 piece seat can be simply adjusted as your little one grows, when your baby is starting to outgrow the snug just remove the seat insert.'

Do a search on Ebay, you will see second-hand ones keep their value well.
