Trampoline Assembly

The easiest way to assemble a trampoline from Trampoline Supplies, is to have at least 2 people working together. Ensure that the ground level of the trampoline site is as level as possible.  If the ground slopes slightly, the long side of the trampoline frame should follow the slope.

Recommended tools for assembling the trampoline frame – a hammer required for hammering in the dowels.

  1. Unpack and lay out all frame parts on the ground in a rectangle with the Leg Sections laying on the inside of the End Frames and the Side Frames positioned between the End Frames.
  2. Working in sync, one person rotates  and holds a Leg Section so that the open end of the pipe is facing upwards and another person slides one Side Frame pipe over the Leg Section pipe. Do the same with the other Leg Section and Side Frame, then slide the remaining ends of the Side Frame over the corresponding Leg Section, resulting in a freestanding frame.
  3. Hammer the dowels provided into each End Frame and then slide each End Frame into the Side Frame, joining the section edges together.


The trampoline is now ready to attach the mat and springs. (Instructions 1, 2 and 3 below are for black poly mesh mats – 2-string mats come with mat wires already inserted. Instructions 4 & 5 are for both black poly mesh and 2-string mats.)

  1. Unpack and lay the trampoline mat on a flat surface or large table.
  2. For right handers, start at the left-hand corner by inserting a Mat Wire into the 2nd hole from the end of the mat (with the kink facing inwards) and push it back towards the 1st hole, using another Mat Wire as a prop.
  3. Continue feeding the first mat wire back into the 1st hole until the kink is in the middle of the 1st hole. Rotate the kink outwards – this is where the spring attaches. Remove the ‘prop’ Mat Wire and repeat the process by inserting the next Mat Wire into the 3rd hole, working back to the 2nd hole, and the next into the 4th hole working back to the 3rd hole etc. Manoeuvre the last Mat Wire on each side so that the kink is exposed. Continue in this way around the four sides of the mat.
  4. Position the mat on the ground within the trampoline frame, attach the short end of 2 springs on either side of each corner of the mat (8 in all) then pull and fix the long ends of the springs in the corresponding holes in the frame at the 4 corners.
  5. Hang the remaining springs on each Mat Wire and, working in pairs along each side of the frame to ensure an even tension on the mat, pull and fix each spring to each corresponding hole in the frame. (If working alone, attach 4 springs on one side then swap over to the other side and attach the corresponding 4 springs etc. travelling in the one direction.) ALWAYS ATTACH THE SPRING TO THE MAT FIRST AND STRETCH BACK TO THE FRAME.


Once the frame and mat are assembled, the safety pads are the last step.

  1. Unpack the safety pads and lay them over the springs along the length and width of the trampoline with the folded (smooth) edge (with the ties underneath) facing inwards towards the mat and the sewn seam (with the Velcro strapping) facing outwards.
  2. Separate each Velcro strip, wrap the soft side (loop) under the trampoline frame pipe from the inside, hold it in place and pull and wrap the rough side (hook) around the soft side so it attaches firmly.
  3. Tie the inside ties loosely onto the closest spring to allow enough slack for the stretch of the springs while people are jumping.

Your trampoline is now set up for action!


Trampoline Maintenance

Over time and with exposure to environmental conditions, residue and grit will collect between the trampoline mat fibres.

To make the mat last as long as possible, it is important to:

  • Keep the mat clear of residue – remove leaf litter and twigs from the mat before jumping.
  • Wash the mat down with a mild dishwashing detergent, rinsing thoroughly with a hose or sprinkler, about once a month.

To prolong the life of a 2-string mat, it should be repainted about every 2 years (depending on weather conditions) using a HIGH QUALITY WATER-BASED EXTERIOR HOUSE PAINT. This can be done by tipping the trampoline on its side and applying the paint with a foam roller to both sides of the mat while it is attached to the frame.

Over time, normal wear and tear, prolonged use and exposure to environmental conditions may cause:

  • the mat stitching thread to break and unravel
  • fraying around the mat wires
  • overstretching of the springs

We recommend that the trampoline be checked every now and then for this kind of damage and action be taken as soon as possible after noticing, to save any further damage to the mat and to avoid potential harm to jumpers. Trampoline Supplies provides a mat restitching service and holds stocks of replacement mats, mat wires and springs (see Parts & Accessories).
