With a fun retro feel (remember these from the 70s?) and fantastic "tub" packaging, these hoppers are brilliant. Sit on the hopper, bounce up and down, race with it - bounce into outer space. As this hopper is over 60cm wide, it is suitable for ages 3+ and can hold over 100kgs. Space hoppers are great for "incidental" exercise - ie you don't even know you're doing it!
