So I bought the new Dream Home Decorator pack and I was very excited to give my sims family a new cozy couch with a chaise longue. 
I expected the sims to be able to watch TV from there, because we already have that interaction for bed. But I found this happens:

When you let the sim to lay down first and then command to watch the tv, the sim will get up to find another seat. 
But when the sim is already watching the tv from another seat and you click on the chaise, the sim will get up to lay down and will continue to watch tv. 

So I guessed this was a bug and was asked on the Sims forum to report it here.
Also an another simmer pointed out in the forum thread, that her sim did autonomously lay down and watch the tv, so autonomy is not a problem. 

In addition I tested it out with toddlers, and no issues there. The toddlers are able to sit there, watch tv and can even talk with other sims. (Would be also really nice to get the option to talk with other sims while laying down, it was a bit dissapointing that it wasn't patched in again...)

I wish this could be fixed and thanks for the help!
