Chair

彼女の椅子の足の高さを1段下げた。初めて椅子に座ってから4ヶ月半くらいたったかな。

I lowered the height of her chair legs by one step. It's been about four and a half months since she first sat in her chair.

すこしまた足を伸ばせる様になって、相変わらず彼女は足を踏み鳴らした。

As she was able to stretch her legs a little more, she still stepped on her legs.

70センチの彼女が椅子をもう一段下げるのはもっと早くなるのだろうか。

Will it be faster for her 70 cm to lower her chair one step further?
