Instead of a coffee table you might want an end table to put next to your lounge. As lazy as it sounds you probably won't want to lean forward to ash or pick up your glass when you are reclined; better to have a table next to you within reach. A standing ashtray would also be a good solution.

Others:

Small sound system
Some tasteful pictures/signs/paintings
Minifridge
Small dry bar w/ glasses and choice beverages

Good luck and HAVE FUN!
