A seat to put in the sun (5)

I believe the answer is:

stool

'a seat' is the definition.
(stool is a kind of seat)

'to put in the sun' is the wordplay.
'put in' is an insertion indicator.
'the sun' becomes 'sol' (I've seen this before).
'to' placed inside 'sol' is 'STOOL'.

(Other definitions for stool that I've seen before include "Small seat" , "Motion" , "Three-legged backless seat" , "Simple seat" , "place butt on one?" .)

I've seen this clue in The Guardian, The Globe and Mail and The Telegraph.
