The Trampoline Mat, sometimes called the bed, is the main part of your whole setup. It ranks among those parts that get little attention until a problem happens, even though it affects everything about the feel of your trampoline. When you search for a replacement note your sizes more carefully than you would assume.
In short, you need three main amounts: the width of the frame, the length of the springs and the number of springs on your trampoline. You measure the full width from the outer edge of the metal frame directly to the opposite outer edge. For the length of springs, measure the trampoline in a loose state…
How to Measure, Repair and Buy a Trampoline Mat
From hook to hook, and avoid guessing when it is already attached. Especially precise knowledge of these details helps find a Trampoline Mat that fits perfectly, from one that simply does not suit at all.
Trampoline Mats come in the average sizes: round of 12 feet, 13 feet, 14 feet and 15 feet, plus square versions like 13 feet by 13 feet. Nicely, some Trampoline Mats from certain makers are so flexible that they work for other brands of trampolines, as long as your diameter, number of springs and lnegth of them match. When you compare offers, look for materials that resist UV rays, that truly protect against sunshine, strong V-rings and extra stitches, sewn tightly for long life.
Some even include bonuses like a tool to attach springs or hooks, which saves money compared to separate purchase of those.
Here is something that commonly surprises users: the Trampoline Mat truly needs a bit of care. When it is too stiff and does not allow air to pass, you simply lose energy from the bounce because of the struggle to push the air out. Professional trampolines in gymnastic halls use those white rubber-style mats that feel surprisingly bouncy, that does not happen by accident.
A Trampoline Mat that flexes under your weight will usually give that thrilling, quickly matching bounce feeling that improves the whole enjoyment.
Not always a small tear means the start of the end. When you have a whole more little than four inches, you can easily patch it. You clean both sides of the tear with rubbing alcohol, stick a patch below and press it firmly down.
Otherwise, take a needle and sew it, no drying time is needed. Anything bigger or in a spot where the tension is strong, though? Usually that shows that the Trampoline Mat reached its end.
Good idea: leave the old Trampoline Mat on the frame until the new one is ready to use. It helps as a good guide for checking size and amounts. Funny enough, sometimes buying a whole new trampoline costs less than just a replacement Trampoline Mat.
Some found a net price of almost ninety dollars for a replacement Trampoline Mat before delivery, while a new 14-foot trampoline with poles, mat and cover for springs cost only hundredtwenty-nine dollars in the store.
Do not expect that stacking a new Trampoline Mat above the old one with double the number of springs in each hole will boost your bounce, it does not work like that. Reading reviews and opinions from others about different brands helps a lot when you choose. The fame of the maker of Trampoline Mats truly matters.
