awwwwwwwwww loved my bumbo you can get a tray to go on the front too. helps secure them in a bit more my lickle lady only managed to get out of hers at 8 months and thats cause i took the tray off for some reason and then when i put it back on i thought she couldnt get out lol i heard my older daughter say mum shes escaped. would recommend them to everyone, but dunno about on a surface that high.
