BERG Grand Champion Inground 520 Grey with Safety Net Deluxe
AirFlow Pro Jumping Mat
Jumping high requires minimal air resistance. The AirFlow Pro jumping mat is specially developed for pros, because it lets 150% more air through than a standard jumping mat!
TwinSpring
You'll jump higher with TwinSpring springs. These springs are cleverly mounted in a V-shape. More springs, and more jumping power.
Extra Thick and UV-Resistant Protective Edge
The extra thick protective edge, 30mm, is made of UV-resistant material to ensure maximium safety and is protected by a 5yr warranty! Even on the highest jumps you're guaranteed a soft landing!
Super Strong Frame
More jumping power means a greater load on the frame. This frame can handle the extra load with ease, so it's extra safe! The entire metal frame is galvanised. The legs and feet are also coated with a black powder coating.
Inground Trampoline Hole:
The hole dimensions should be 480cm x 300cm and 80cm deep along the middle of the hole. The hole should be bowl shaped towards the edges. The trampoline will sit around the outside of the hole. DO NOT dig the hole before the trampoline is delivered as you will get the curved ends the wrong shape, you need the trampoline bed to markout the hole shape. The trampoline is slightly raised above the ground to allow the air to escape from under the trampoline. If the air can not escape it will reduce the bounce quality when it is being used.
The BERG Champion trampoline line offers fantastic jumping comfort, and is ideal for jumpers who have a little more experience. The Champion is a high-quality trampoline that is designed to allow you to jump safely for a long time. The combination of the TwinSpring springs and the AirFlow Pro jumping surface provide lower air resistance and a larger jumping surface. Both of these features let you jump better and higher! Available in regular and InGround.
This BERG Grand Champion Inground 520 Trampoline Package Includes:
520cm x 345cm (17ft x 11ft 4") BERG Grand Champion trampoline with grey pads.
AirFlow Pro bed for a stronger, higher bounce. The mat allows 150% more air through than a standard jumping mat. This reduces resistance and makes jumping easier. With less force, you get more results

Trampoline installation is available - this does not include digging the hole, it must be dug and ready for the trampoline to be installed over the top.
Trampoline Frame
Round 48mm x 2mm gauge galvanised steel frame covered by a 13 year warranty against rust causing failure. Welded slot together frame, with heavy duty nuts and bolts makes for a stronger constuction. Locking legs and feet make for easy maneuverability.
BERG Deluxe Safety Enclosure:
8 curved poles each covered in a long lasting PVC protective sleave. The net is supported all around the top so that the net remains tight at all times.

AirFlow Pro is the perfect trampoline jumping mat for you. It lets 2.5x more air through than a standard canvas and 65% more than the BERG Airflow bed. You immediately feel less resistance and more easily reach greater heights. Rise above yourself with AirFlow Pro.
Frame Pads:
Trampoline
30mm thick pads are made from closed cell foam to exclude water. The Pads have a heavy layer of PVC which will last much longer than inferior PE.
The pads are 39cm wide to ensure there is no chance of jumpers landing on any exposed part. The Pads are securely tied to the frame of the trampoline to ensure they are always in the correct position. The padding covering is also UV treated to protect against harmful rays from the sun.
Surround:
Uprights covered in EPE foam which are housed in substantial PVC sleeves
Trampoline Safety
No more than one person at a time on the trampoline. Multiple jumpers increase the risk of injury. Do not perform somersaults (flips), paralysis or death may result if you land on your head or neck. Adult supervision recommended. Please leave a 2m safety zone all around your trampoline

1/5 Marking trampoline
Decide where you want to place the trampoline in the ground. When doing so, keep 2 metres away from other obstacles for a safe jumping experience. Mark the location on the ground as shown in the manual. When doing so, keep to the dimensions given in the manual supplied with the trampoline.
-
2/5 Dig out the edge
Then use a shovel or spade to cut out the edges inside the circle. From that edge, you can then shovel out the middle section. If you shovel the soil straight into a wheelbarrow, you will keep the grass nice and clean.
-
3/5 Dig out the entire hole
Dig out the hole in a bowl shape and to the depth indicated in the instructions. It will take some time, but do remember that it won't be long before you can enjoy jumping on it. It's so worth it!
-
4/5 Placing the trampoline
Wow, that looks sleek! Well done. You can now place the trampoline over the hole. Follow the last step in the instructions, and you are ready to jump.
-
5/5 Ready to jump!
The trampoline is ready for use. Invite everyone in the street to your debut on your new BERG trampoline and make a party of it. The Sky is Yours!

BERG Inground Hole Dimensions
This chart shows all of the different sizes of Inground trampolines that we can offer. Please ensure that you look at the correct shape and size so that you have the correct hole dimensions.
The hole should be bowl shaped and the trampoline will sit around the outside of the hole. Do NOT dig the hole bigger than the dimensions shown as the feet will to close to the edge of the hole.
The trampoline is slightly raised above the ground to allow the air to escape from under the trampoline. If the air can not escape it will reduce the bounce quality when it is being used.
The rectangular or Ultim 410 x 250 size is not available as a Champion inground. It is however available as a Flatground in the Champion range. If you want this size as an Inground you will need to look at the BERG Favorit range.
