Design details

EXCLUSIVE SUPPORT FROM DECATHLON'S DESIGN TEAMS
The Trampoline 420, designed entirely by Decathlon product managers, designers and engineers, is one of the 7 trampolines (model codes 8872323, 8799831, 8799838, 8799832, 8799837, 8753805 and 8529108) on our website to be covered by the Decathlon warranty. Buy with peace of mind thanks to our knowledgeable experts who can help you install, maintain and repair your trampoline and provide in-store and after-sales support.
CERTIFIED CE STANDARD
Complies with CE trampoline standards (EN 71-14, EN 71-1 2014+A1:2018, EN 71-2:2020, EN 71-3+A1:2021). These standards outline the requirements and testing methods applicable to trampolines used for at home. These requirements and test methods cover the following (among other things): construction, structural resistance properties, shock absorption, and even jumping surface deformation... Reports are available on demand.
EASY SET-UP AND STORAGE
This trampoline is assembled and disassembled with no screws or tools. The parts connect to each other, ensuring its durability and ease of installation and winter storage. The net posts fold down without tools in a few seconds, so that you can install our protective tarp (sold separately) in just a few seconds and reduce its wind load by nearly 50%. (wind tunnel test). Our pairs of adult testers took up to 50 minutes to assemble the trampoline.
SAFETY DURING USE
Our product design is guided by the safety of our young users. - A stretched protective net made from polyethylene material and an entry lock ensure that the jumping area is always closed and secure. - The net posts are far from the jumping area and surrounded by embossed protective foam pads. - For greater safety, the net is designed to prevent access to the springs when on the jumping surface. - Spring protection foam is 30 cm wide by 20 mm thick.
SAFE MATERIALS
All our trampolines not only comply with trampoline standard EN 71-14 and toy standards, but have also undergone many additional tests by accredited external laboratories to ensure that they do not present any health risks to our youngest users (Phthalates, Formamide, bisphenol A, S).
DURABILITY OF METAL PARTS
Our materials are sturdy. - All of the tubes on the frame are warrantied for 5 years and comply with ISO 8493 and ISO 8492 standards to ensure the stability of their resistance. Made of heat-galvanised steel, they provide excellent rust resistance. - All of the springs, with a 24 mm diameter and 29 spirals, are made of steel treated to prevent rust via electro-zincing. They have a 4N/mm stiffness. In the lab, they undergo 45000 cycles of extension from 15 to 95 mm without breaking or failing.
DURABILITY OF SOFT PARTS
- The polypropylene jumping surface withstands UV rays (material used for sailing boat ropes) - The UV-resistant protection net made from polyethylene material withstands tensile forces far beyond standard conditions of use. - The foam protection on the posts is embossed with a crossed weave for more lasting durability.
Stability
The 4 W-shaped feet with 2 points of contact ensure optimal stability. The stability is tested in use and in the lab for strict compliance with standard EN71-14 to ensure a dynamic user weight of 110kg and a static deflection of the jumping surface of 550kg.
BOUNCE QUALITY
The 88 springs, with 29 spirals of 24mm diameter and 141mm length, have a tensile strength of 57N. Combined with a 377cm diameter jumping surface, they ensure an excellent bounce quality and comfort thanks to their progressive shock absorption.They're adapted to suit a wide range of jumper weights, especially the lightest, to ensure excellent comfort, while offering great resistance for the heaviest of us.
WHY A 110 KG USER, WHEN THE COMPETITION OFFERS TRAMPOLINES FOR 150 KG USERS?
Most jumpers weigh between 20 and 50 kg (ages 6 to 12)... But we know that adults love to jump, too. So we've designed a product with great durability (550 kg static), BUT WHICH IS GOOD FOR CHILD DEVELOPMENT. Why 110 kg and not 150? Because at 150 kg, to meet the durability standard (750 kg), we would need to use springs that are too stiff and which would harden the jumping surface. This would interfere with the joint strengthening of users under 40 kg as they jump.
REPAIRABILITY
100% of the trampoline's components are available as spare parts for 10 years after the date of the last item sold. Each spare part comes with a tutorial for easy replacement at home. Parts can be ordered via the after-sales service link a bit further down the product file.

Recommendations
The masts and protective netting are safety devices, so it's essential to check that they're still in their original condition each time they're used, in particular that the flaps of the entrance hatch are still correctly positioned one on top of the other or that none of the structure's masts have been damaged or bent.If you discover any damage, contact our after-sales team. It is strongly recommended that jumpers wear socks with silicone pads to prevent slipping.
Restrictions
Model designed exclusively for outdoor use. By law, this trampoline is forbidden for children under the age of 3. Above 3 years, it's authorised under parental supervision. Standards stipulate that only one jumper may be on the trampoline at a time to avoid collisions and injuries. We strongly suggest you leave a space of 2 metres around your trampoline. It's essential to check the condition of the trampoline before each use. Read the instructions carefully.
ASSEMBLY TIP
Want to prevent your trampoline from making noise? We have the solution! When assembling your trampoline, lubricate the metal joints with Teflon grease to prevent them from rubbing together:
