I already have one of these in blue for my eldest son, i purchesed this for my youngest daughter who is two.
The First Years Winnie The Pooh - On The Go - Booster SeatI think these booster cushions are brilliant. I use them in my home everyday, they are perfect for when your child becomes that little bit too grown up for the high chair and wants to sit at the table with mummy and daddy like evrybody else.
They are quick and easy to move about and hold the child in securely. As for washing, it says to wipe clean only on the instructions, but i have put it in the washing machine umpteen and it comes up like new, be sure to remove the inflatable cushion and zip it all back up, securing straps before.
These are brilliant too for eating out, high chairs always look suspicious too me, never really wiped properly, so i always take one with me. Not only does it give you peace of mind, but it means they can join the family around the table. There are pleanty of secure straps to keep them prisoner!!
If you're thinking of buying one, go ahead. You'll not regret it. For the price you will get yur moneys worth.
