I did the same as exbiker - a few offcuts of MDF 1x1 frame to strengthen and a couple of hinges. Covered in carpet offcuts left over from the NEC stand last Nov. - if you want some & are in the area of Derby let me know! Total cost - about 99p for hinges.
Alternatively swmbo likes to rest her feet on an Aldi bag made for cars -n a black carpet type material which I keep all my bits & bobs - usually on the back shelf - £4-99 next time they have them in. Bargain!
