DD (9) would like a gymnastics mat for christmas but I cant quite decide what size to get. Don't want to get one that is too large for the house but at the same time don't want to get too small either. This is the one I was thinking of www.amazon.co.uk/gp/product/B008DH9IGE?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A3K3VRHZ6NVUPJ
Does anyone have one and can advise? Its mainly for practisicng her hand stand, walkovers etc
