Safety is of the uttermost importance so inside the padding you'll find 20mm thick EPE foam protecting your child against the steel frame.
- Even before gaining EN71 certification this trampoline went through extensive testing at the Zero Gravity testing lab. Including 500KG weight testing and cycle testing. Did you know that while a welded trampolines frame will typically crack at 1 million cycles this trampoline has gone through over 2.5 million cycles without cracking.
- Customer service is key to Zero Gravity Trampolines success. Although we believe the assembly guide supplied with this trampoline is one of the best available, should you have any questions while building your trampoline please feel free to call the Zero Gravity support line and one of their knowledgeable staff will be only to pleased to help.
Cons
- Frame may crack under extreme use.
- Assembly guide requires customer support assistance.
FAQ
What does the size on a trampoline listing mean?
Trampoline sizes are usually given in inches and refer to the diameter, which is the width across the center of the jumping surface.
How do I measure my available space for a trampoline?
Measure the length and width of the area where you plan to place your trampoline. Ensure there's enough clearance above it too.
What size should I choose if I have limited outdoor space?
For small spaces, opt for a mini-trampoline with a diameter of around 6 to 7 feet; these are easier to store and less intrusive.
How many people can fit on a standard-sized trampoline?
A regular 12-foot trampoline is suitable for one or two people at a time, while larger sizes accommodate more users safely.
What size should I choose if I have a large garden?
For bigger gardens, consider a 14 to 16-foot trampoline which can handle multiple users and provides ample space for jumping.
Can I use a larger trampoline in a smaller space?
Avoid using larger trampolines in small spaces as they require more room for safety and stability, risking damage or injury.
How do I measure the clearance height needed for a trampoline?
Measure from the surface of your ground to any overhead obstacles. A minimum clearance of 10 feet is recommended around the trampoline perimeter.
What size trampoline would be best for kids?
For children, consider a smaller trampoline within their reach and safety limits, typically up to 8 to 10 feet in diameter.
Can I use a large trampoline in an indoor space?
Large outdoor trampolines are not recommended for indoor use due to size and safety concerns. Smaller indoor models or rebounders might be more appropriate.
How do I find the right size based on family needs?
Consider the number of users, space available, and activity level. A trampoline should be big enough but not so large it takes up too much room.
In depth
When it comes to trampolines, understanding the size descriptions can be crucial for ensuring you choose the right one for your UK home and garden. Trampolines are typically described by their diameter in inches, which refers to the width of the jumping surface rather than the overall frame dimensions. A 10ft (304cm) trampoline is more accurately referred to as a 12ft (365cm) model because manufacturers measure from edge to edge through the centre. This can be confusing for buyers, so it's important to clarify with specific measurements when comparing models.
For smaller spaces or homes with limited garden area, a compact 8ft trampoline is often sufficient and safe. These are perfect for backyards that might only have room for 10-20 square metres. However, keep in mind the common sizing mistake of underestimating the space required around the trampoline to ensure safety. A standard rule of thumb suggests allowing at least a 6ft (183cm) clearance from any walls or obstacles on all sides. This means that for an 8ft trampoline, you need roughly 20-24 square metres of open space.
Larger families and those with ample garden space might opt for mid-size trampolines measuring between 12ft to 15ft (365cm - 457cm). These models offer more jumping surface area and are better suited for multiple users. However, they require significantly larger spaces—around 30-40 square metres—and should be placed at least 10ft (304cm) away from any structures or hazards. Misjudging the space requirement can lead to accidents or property damage, so careful measurement and planning are essential.
The largest trampolines on the market, measuring over 16ft in diameter, provide an exhilarating jumping experience but demand considerable space—typically around 50-75 square metres—and should be positioned at least 20ft (609cm) away from any buildings or trees. These behemoths are not suitable for small gardens and are best suited to large backyards with ample room for safety zones.
Another crucial aspect of sizing is the weight capacity, which can vary widely depending on the model and manufacturer. Smaller trampolines may have a maximum weight limit around 200lbs (91kg), while larger models can support up to 450lbs (204kg) or more. For families with children of varying sizes, it’s important to choose a trampoline that meets the weight needs of all users. Overloading a trampoline not only risks damaging the structure but also poses significant safety hazards.
Lastly, consider the layout and design of your garden when choosing a trampoline size. Flat ground is essential for stable placement, and uneven surfaces can lead to wobbling or instability during use. Additionally, avoid areas with strong winds or proximity to large trees that could interfere with landing zones. Regularly checking the manufacturer’s guidelines for safety zones and recommended clearances will help ensure you make a well-informed decision that maximises both fun and safety for your family.
