JumpSport 350/370 Springfree Mini Trampoline Review 2018

Enjoy a safe low impact (springfree!) workout any time day or night with the virtually silent JumpSport 300 series mini trampoline rebounders…

As you would expect from a name like JumpSport, these are high quality rebounders and feature the latest EnduroLast technology  – 4/6 adjustable elastic (bungee) cords in place of the traditional steel springs, designed to last 4 -6  million bounces.

As an added bonus the elegant JumpSport 300 series also feature FlexBounce III and VII technology, which allows you to quickly and easily adjust  mat tension and firmness.

The springfree JumpSport 350 is a real alternative to traditional steel spring rebounders.  It’s very smooth to use and looks really great too, the factory setting is 160 lbs user weight, but you have the option of three different settings to give you the perfect bounce based on weight… stiffer or softer…

FlexBounce III and EnduroLast technologies combine to offer a really superior stress free bounce, helping you stay healthy, happy looking and feeling great!

The main difference between spring and springfree rebounders is generally springfree rebounders give a, gentler, smoother and quieter bounce and spring rebounders can become squeeky over time, which to most this is not a problem, but is you like you’re quite or you like bouncing at night; this may be the option for you…

Another feature we like about the springfree JumpSport 350  mini trampoline rebounder, are the arched legs  which differ from most mini trampolines that have straight legs, these patent pending arch legs give really great stability and safe feeling platform even without the jump handle.

This is a high quality solidly built springfree trampoline rebounder built to last many years of regular use and if you are looking for an alternative to a traditional spring this may be the one for you… It comes with a free basic workout DVD detailing beginner, intermediate, and advanced exercise routines such as warm up and Stretching, Cardio, Strength, Upper Body and Core.

On the down side the mat is only 33.5” compared to many mini trampoline mats at 40” but this works fine if you are not an especially large person say up to 5’8, 250 lbs.

JumpSport offer a lifetime warranty on the Steel Frame & Legs, 5 years on the mat, 4 years on the EnduroLast 4 Elastic Cords and 1 year on all other components.

JumpSport 370 Springfree Mini Trampoline

In addition to the JumpSport Model 350 Mini Trampoline, there is also the 370 model which in our opinion is even better… it is a little more expensive – but that’s because it’s better! Quality will always be more expensive but then buying budget can work out expensive in its own way…

The primarily difference between the two models is in the mat design and elastic cord technology. The JumpSport 350 has a 4″ Permatron mat skirt that extends over the elastic cords to give a total area of 33.5″.

The 370’s Permatron mat has six 6” x ½ “foam padded petals that extends from the jump area and completely cover the elastic cords, to give a total area of 37″

Both models feature EnduroLast and FlexBounce technologies. EnduroLast 6 cords on the Jumpsport 370 are designed to last over 6 million bounces and have a warranty for 6 years as opposed to EnduroLast 4 on the JumpSport 350 which is 4 million bounces and a 4 year warranty; both models have a lifetime warranty on the frame. The JumpSport 370 also has an extended 4 in 1 workout/fitness DVD.
