My daughter wants to get an air track for the garden, she’s a cheerleader and ex gymnast so thinks it will help get her tumbling back. Is it worth it? Do people recommend the 20cm one over the 10cm as she believes 20cm would be better. I’ve come across this one online www.<a class="break-all" href="https://amazon.co.uk/gp/aw/d/B07FJ6X6RH/ref=sspa_mw_detail_1?smid=AFEFQ6F2S04NI&psc=1&th=1&ie=UTF8&tag=mumsnet&ascsubtag=mnforum-shopping-3579278-Air-track" rel="nofollow" target="_blank">amazon.co.uk/gp/aw/d/B07FJ6X6RH/ref=sspa_mw_detail_1?ie=UTF8&psc=1&smid=AFEFQ6F2S04NI&th=1 has anyone bought this one before? Are we better off buying one from an air tack/sports company? Thanks!
