About Big On Bouncing

Big On Bouncing is a family-run indoor soft play centre on Kelpatrick Road in Cippenham, Slough, built for under-8s and well known locally for its bouncy castle hire business. Parties here are refreshingly private: the weekend package hands the whole centre to your group for two hours - bouncy castle, soft play frames and sensory equipment included - with dedicated party hosts, a private upstairs party room and children's tableware, while a cheaper term-time weekday option runs after school for smaller groups with unlimited juice and one adult included per child. The cafe stays open throughout, food platters can be added, and the centre is strictly nut- and seed-free with monthly SEN sessions - a genuinely inclusive setup. Parents rate it 4.8 stars from around 240 Google reviews, and its pages are kept current with clear terms (deposits, balances and access notes all published). One practical note: the party room is upstairs, so tell the team ahead if any guest cannot manage stairs; parking is free on site

    We brought our son Adam today with the Rainbow Trust team and he had such a blast! The staff are wonderful here and the environment was brilliant for my son, he had the time of his life today so thank you for putting a smile on his face. We will definitely definitely be back again and have already recommended our family members and friends to come and join us in the sessions. Thank you once again!

    Best soft play we've ever tried. Went with a 16-month old on a quiet Friday afternoon and they had an absolute blast. Great bouncy castle, slides, light games, the 90 minutes whizzed by. It was also spotless. Haven't tried the food or drink from the cafe but had a nice chat with the owner Karen. We'll definitely be back!

    Great place to hold a birthday party or let the kids get some steam out. Had a 6th bday party for my boy here recently. The staff were friendly and place was clean and good choice of food for adults and children. Can’t go wrong.

    My partner and I took the little ones to soft play today. Both had an amazing time. If you’re looking for something modest and homely. This is the place to go. I was able to see my older child play whilst I was in the baby area with my littlest one. Staff are lovely and welcoming and engage with the parents and children. Very affordable. Both the cost of the soft play itself and the cost of food and drink served inside with plenty of choice. The place is well maintained and clean. There are plenty of activities/toys/playing area for the kids to tire them out without overstimulating them. I would recommend and will be returning again. This is a hidden gem.

    We were greeted by a really lovely man who helped us into the building (holding doors etc for the double buggy). You have by to ring the bell to be let in which with young children I really like as not just anyone can walk in. With a nearly 2 and 5 year old this place is amazing. It’s the perfect size for them and has so many sensory activities. I really can’t rate it highly enough - 6 out of 5 stars. It is in such a good condition and there are lots of little touches and details that make it so lovely.
