Translations for upstairs in French

Here are paragraphs from public domain books translated:

Between us, with much trouble, we managed to hoist him upstairs, and laid him on his bed, where his head fell back on the pillow, as if he were almost fainting.	À nous deux, et non sans peine, nous arrivâmes à le porter en haut et à le déposer sur son lit. Sa tête retomba sur l’oreiller, comme s’il allait s’évanouir.
