Some photos of size 2 meh dai's in action. The height of the meh dai (mei tai) can be shortened by rolling the base, or wearing the waist apron style. Available with a curved or flat top edge (no headrest). When you fold over the headrest the opposite side will show so choose two co-ordinating fabrics or choose a meh dai (mei tai) with a straight top edge. Body panel height (excluding waist band and curved top edge) is 42cm (16.5") X 43cm (17").
