Overbed table - stable (moves on runners, not castors?) (Scriven HG5)

Useful as bed side table or as overbed table for drinks, magazines or anything else that needs to be handy for use, or nearer to see. Brown strong runners and underside. Height adjustable. Lighter colour laminated top (wipeable and hygienic). Would suit small laptop or I-pad use but NOT really big enough for a computer with separate keyboard, Radio would be good. Mealtimes or a snack? - Ideal at bedside or over bed. One narrow rail on each side of table length to prevent any sliding. Ideal for bedside chair "overtable" when change of position is required.
