reasonable lifting system for the price, I would recommend a few changes to the supplied fittings though. The nuts supplied are ok if room is at the sides is not a problem but when your bed is next to a wall the nuts will stick out. I would suggest also supplying the nut I have pictures in the second photo as an extra and up teh price.Also the you (seller) could save your self administrative time of having to to read and answer emails if you put the instructions in the box or even a just a typed link to the site on a sticker on the box where the instructions are stored. Just a thought.
