Step One - Set Up the Frame and Mark the Digging Area

Start by assembling the frame. You don't need to fully assemble it, just take it where you can mark the digging area.

Begin assembly in the area where you plan to dig the hole. Make sure the spring holes are pointing up. It can be done with one person, but with two it's faster.

After assembling the frame, find a way to mark the area you want to start digging (you can use spray paint). You can add about 2-5 inches to the frame outline to make it easier to insert into the hole. Remember you can reload this one.

Once you've built your frame and marked out an area, you can start clearing a section of lawn for later use as infill. You don't have to save the entire lawn, just enough to cover your tracks.

Step Two: Dig the Hole

Once you've accumulated enough grass, you can start doing whatever you want and dig the hole. The first excavation consists of descending to platform level. Check the manual for the depth needed for the overhang, but you should use a gauge to complete each excavation. First, dig to this depth throughout the hole (not just the frame), making sure to measure all sides at several points every few feet.

After digging the first hole, mark the area for the next hole. Again, see size requirements for shelf length requirements. It's safe to add an inch or two as it will fill in that area. Then start digging the second hole that will serve as the jump area, also known as the bowl area.

The sides of the hole don't need to go straight down. They should be quite steep, but feel free to go down at a good angle. This minimizes the amount of soil you have to dig.

Step Three - Complete the frame and place it in the hole

After digging the hole, it's time to assemble the frame. To do this, you need to fasten the supporting walls with a screwdriver.

The supporting walls should already have screw holes, so just line them up and start screwing. It's best to start with the top holes first and then move on to the bottom holes to complete the joint. Once you've done that, place the frame in the hole and place it on the shelf to make sure it fits properly. If it fits correctly, you can continue; otherwise, you will need to make adjustments.

Once you know the frame will fit, you can install the membrane. Once you've done that, lower the frame into the hole and proceed to the next step.

Step Four: Attach the Springs

Once the frame is in the hole, you can start attaching the rug to the springs. When installing a rectangular trampoline, you should start with the four corners and the center of the sides and then work from there. When you work with someone opposite, it becomes easier because the tension is uniform.

Once you put the springs in, you'll find that the frame has changed quite a bit. At this point you should do a little test run with your trampoline, bouncing up and down on the mat to make sure everything is secure.

When everything looks right, you can start filling in the space between the outside of the retaining wall and the ground. Try not to put soil in the bowl area. When you're done, pack it well and cover it with some of the grass you've saved.

Step 5 – Attach the Pillows

The final part of the assembly is to place all the pads. It's best to place all switches on the pad first, with the round ball facing the inside of the pad. Once attached, turn the pad onto the trampoline and start securing it by placing the levers on the frame. Your manual should have clear instructions on how to do this.

Step Six: Have fun!

That is all! You've now completed the DIY assembly and are ready to go. Try it right away and see if everything feels right. Now you're ready for some good old-fashioned fun for years to come!
