One puts gear on sideboard (7)
I believe the answer is:
dresser
This clue is a double definition.
'one puts gear on' is the first definition.
(someone putting clothes or gear on)
'sideboard' is the second definition.
(I know that sideboard can be written as dresser)
(Other definitions for dresser that I've seen before include "Item of bedroom furniture" , "Tool for smoothing" , "One putting things on" , "Surgical assistant" , "Welsh sideboard" .)
