I've been asked to fit a loft ladder for someone who has a hatch 65cm square and limited height in the loft of 65cm to store the ladder.

Looks like we need a concertina one or a telescopic one.

Anyone any experience of telescopic ones? They seem to be about £200. I reckon concertina ones aren't as good as they tend to bounce up and down as you use them which can be unnerving!
