Note: The 12 Foot Trampoline Has 8 Enclosure Poles – Not 6 As In The Image The Air League 12 foot in ground trampoline is perfect to get everyone off the gadgets and into the garden and with such a high specification it is equally suitable for parents as well as the kids. In Ground trampolines have several advantages, due to the reduced height they are less visible, so they won’t spoil the look of your garden as much as a normal trampoline might do. They are also a lot easier for everyone to get on and off. Being In the ground the trampolines are more stable and once anchored to the ground they are a lot less likely to blow over in high winds. The fact that the bounce mat is situated at pretty much ground level also brings with it obvious safety benefits, so much so that most companies only offer in ground trampolines without enclosures. We on the other hand have decided to take a different approach and only offer our sunken trampoline range with enclosures. We decided to do this mainly for safety reasons, without an enclosure fitted jumpers could still be falling from a height onto the extremely hard surfaces of the trampoline frame or retaining wall. A lot of in ground instillations need there to be a gap between the retraining wall and the trampoline to allow air flow, this creates a danger for users which the inclusion of an enclosure reduces the risk of. Another factor in the decision was that having an enclosure fitted enables you to site your trampoline in areas that would otherwise have dangerous objects such as walls, fences, hedges, sheds and other garden features too close and in gardens that otherwise may have been considered too small for an in ground trampoline. Frame The frame of the trampoline has been specially designed for sinking and has shorter legs to reduce the size of the hole needed to successfully sink the trampoline and to help it sit as flush to the ground as possible. It is built with a hot galvanised 1.2mm frame tube that helps cope with the extra demands that being sunk in the ground brings. The HOT galvanisation process ensures that the trampoline frame sections are galvanised inside and out, this is better for garden and outdoor use. (unlike most other cheaper trampoline frames that are only galvanised on the exterior of the frame) We are that confident of the quality of the trampoline that we offer a 5-year frame warranty, ensuring your family will get years of enjoyment from your purchase. Springs Spring quality and quantity should be set up dependant on the most common user weight. Generally, more or stronger springs are required for heavier users but too many springs can affect performance for lighter users. The Air League 12ft trampoline comes with 54 Galvanised and Zinc plated 140mm Max Bounce springs. This is the optimum number of springs required to give the maximum bounce for the lighter than average user weight (under 10 stone) but will still perform well all the way up to the maximum user weight. Bounce Mat All Air League trampoline jump mats are made in the USA and manufactured from Grade A Permatron. Permatron is a unique material that can be left outside all year round as it is weather proof and gives an excellent cushioned bounce due to being easy-draining and air-permeable. The latter helps with improving air flow which can be a real issue for in ground trampolines. We have experimented with cheaper Permatron mats manufactured from outside of the USA but found the quality to be considerably poorer. The V rings used to attach the jump mat to the springs are secured with eight rows of stitching for extreme durability. Safety Padding Air League 12ft trampoline safety padding uses a special shock absorbing closed cell polyethylene to provide protection from the trampoline frame and springs. There is an extra thick layer of padding around the edge to provide added protection from the hard steel frame of the trampoline. The covering of these deluxe trampoline pads are also UV treated to protect against harmful rays from the sun. Safety Enclosure Our enclosures sit inside the spring padding to keep users inside the jumping area. Getting on and off the trampoline is extremely easy for parents as well as children as the net is fitted with a 2-way zip that runs very high up the enclosure net and along the bottom of the jump mat making a very large L shaped entrance which we have found to offer the best compromise of easy entry and security. The mesh of the safety net is made from super strong and flexible Terylene thread that won’t rip, fade in sunlight or rot in the damp British weather. The intelligent design utilises cleverly angled poles to minimise the risk of accidents involving the enclosure poles. These poles have foam impact padding covers fitted to further protect users and are covered with a pvc sleeve to protect this important safety feature from the elements. Combining these features with the vertically running net and this really is an extremely well thought out and safe enclosure. The trampoline enclosure poles click together easily but due to the clever design remain in place even when faced with an out of control jumper to catch. The enclosure net is securely tied to the jump mat to keep users safely inside the trampoline and also drastically reduces the chances of accidentally landing on the spring padding or worse still the top rail poles or retaining wall. The fibre glass poles that run around the top of the enclosure ensure there is no sagging of the top of the net and help the net to run vertically down to the edge of the jump mat.
