When I was little I would go daft for Bouncy Castles and if I am honest, I still do. We have the Bestway Kiddie Play Centre Bouncy Castle and my little one has had his use out of it this summer, even though the weather has been iffy. Very have reduced it since I bought it, and it's now only £25. It was originally £36, so this is a great price.
The Bestway Kiddie Play Centre Bouncy Castle isn't a big, giant inflatable, but a nice manageable size that will fit in most gardens and can even be used indoors, if space allows. To give you an idea, it's most suitable for children aged three to six years old.
This doesn't come with a pump, but I would suggest a foot pump over a hand pump or you will be all day. I am naughty and use an electric one but that is NOT recommended.
There are activity rings on the side of the castle and a ball suspended above. This is without a doubt a bit of fun for the kids, and at £25 it's not going to break the bank.
You can pick up the Bestway Kiddie Play Centre for FREE when you use Collect+. You just select a local participating shop near you and then go and get it at a time convenient for you. It's handy for those of you that work, so you don't miss a delivery. If you would like home delivery then it costs £3.95.
