How to assemble a trampoline

A garden trampoline goes together as a ring frame, legs, a mat on springs, a pad over the springs and a safety net. The spring stage is the hard work; a spring puller tool and a helper make it much easier, and a level site makes it safer.

Tools needed

  • Spring puller tool (often supplied)
  • Rubber mallet
  • Work gloves
  • Spirit level
  • Ground anchor kit (recommended)

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Top ring sections and T-joints
  • Leg sections (W-shaped legs)
  • Jumping mat and springs
  • Frame pad
  • Net, poles, sleeves and fixings

Step by step

  1. Step 1: Choose a flat, open area with clear space all around and overhead: no fences, trees, washing lines or walls within the distance the manual gives.

  2. Step 2: Lay out the ring sections in a circle and join them, fitting the T-joints where the legs attach.

  3. Step 3: Fit the leg sections into the T-joints, then turn the frame the right way up with your helper.

  4. Step 4: Lay the mat in the middle, with its V-rings evenly spaced. Hook on four springs at 12, 3, 6 and 9 o'clock, then work opposite pairs so the mat stays centred.

  5. Step 5: Keep fitting springs in opposite pairs until all are on. Use the spring tool and keep your face away from the spring being stretched.

  6. Step 6: Fit the frame pad so it covers every spring and the frame, and tie it on underneath.

  7. Step 7: Fit the net poles to the legs, slide on their foam sleeves, and hang the net, closing the entrance as the manual shows.

  8. Step 8: Check it is level and fit ground anchors, especially in windy areas, before anyone jumps.

Common mistakes

  • Fitting all the springs on one side first, so the last ones will not stretch far enough.
  • Placing the trampoline on concrete or near a fence.
  • Leaving the net entrance open or unzipped.

Safety notes

  • One jumper at a time is the safest rule, and always with an adult nearby for young children.
  • Anchor the trampoline: strong winds can lift and move it.
  • Check springs, pad and net regularly and replace worn parts.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
