Back again,
I forgot to tell you about the alternative I found.
It's a little pricier at £11 but does come with sliders. But I haven't been to ikea yet to actually examine one ( I can't driveand they seem to pick spots away from bus routes) so if anyone has a chance I would appreciate a first hand report.

Its actually slightly larger than the serilite as far as I can see as well.
