Quietly go out on beach with recliner? Because beach is this? (8)

I believe the answer is:

pebblier

'because beach is this?' is the definition.
I know nothing about this answer so I can't tell whether this works.

'quietly go out on beach with recliner?' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'go out on beach' becomes 'ebb'.
'with' means one lot of letters go next to another.
'recliner?' becomes 'lier' (I can't explain this - if you can you should give a lot more credence to this answer).
'p'+'ebb'+'lier'='PEBBLIER'

I've seen this clue in The Times.
