Yes, the Wickes-branded generic adjustable steel trestle (bench).
Can't see them currently listed at Wickes, but here currently is a really good price for the same units from a supplier I can recommend:
HOMCOM Set Of 2 Steel Saw Horses Telescopic Builders Work Bench Folding Blue

I found the Draper branded ones at just a little more - which I believe are a little better in some areas.
Even so I improved them by substituting heavier nuts/bolts and re-engineering the drop locking bar pins for the uprights (replacement bolt with a collar of nylon tube).
