When most people think of bouncy castles, they imagine children laughing, jumping, and burning off endless energy. But one of the most common questions we’re asked is: “Can adults go on a bouncy castle too?” The short answer is yes — but only on the right type of inflatable.
Whether you’re planning a birthday party, a wedding reception, or even a stag and hen weekend in South Wales, there are bouncy castles and inflatables designed specifically for grown-ups. Here’s everything you need to know.
Are All Bouncy Castles Suitable for Adults?
Not all inflatables are built to take adult weight. Standard children’s bouncy castles are designed with smaller users in mind, and the material, stitching, and seams are not reinforced for heavy loads.
If adults use a children’s inflatable, it can:
-
Cause damage to the castle
-
Create safety risks for kids using it at the same time
-
Lead to injuries due to weight and size differences
That’s why most hire companies (ours included) will ask about the age group before recommending the right inflatable.
What Makes an “Adult Bouncy Castle” Different?
Adult bouncy castles look similar to children’s ones, but there are some key differences:
-
Stronger materials and reinforced seams – designed to hold more weight.
-
Larger size – typically much taller and wider than standard castles, giving plenty of space.
-
Higher walls and deeper beds – so adults can jump safely without “bottoming out.”
-
Weight capacity – built to accommodate multiple adults at once.
These castles are popular at corporate fun days, weddings, and community events across Wales, where the grown-ups often can’t resist having a go!
Can Adults and Children Use the Same Castle?
Mixing adults and children on the same inflatable is generally a no-go. The difference in size and weight creates a big risk of collision and injury.
The safest option is:
This way, everyone gets to enjoy the fun without the risks.
Popular Inflatables for Adults
While standard castles are great, there are also other inflatables that work brilliantly for adult hire:
-
Inflatable obstacle courses – perfect for team-building, school reunions, and stag/hen groups.
-
Inflatable slides – bigger models are suitable for both kids and adults.
-
Adult disco domes – a castle and party tent combined, often with lights and music.
In South and West Wales, these options are especially popular for weddings, student parties, and family fun days, where everyone wants something a bit different.
Safety Rules for Adults on Inflatables
Just because the inflatable is designed for adults doesn’t mean safety can be ignored. Here are the golden rules:
-
Follow capacity limits – don’t overload the inflatable.
-
No shoes, food, or drinks – just like with kids’ castles.
-
Supervise at all times – even adults can get carried away.
-
Weather checks – inflatables should never be used in winds above 24mph.
By sticking to these rules, you’ll make sure the hire is safe and enjoyable for everyone.
Why Adult Inflatables Are Great for Events
Adding an inflatable for adults isn’t just about fun — it’s a fantastic icebreaker. We’ve seen it time and again at weddings and corporate parties in Wales: once one person gets on, everyone else soon follows!
It:
-
Creates laughter and memories
-
Encourages teamwork and friendly competition
-
Appeals to the “big kid” in everyone
If you want your event to stand out, an adult bouncy castle is guaranteed to be a talking point.
