Sims with expensive couch getting the uncomfortable furniture moodlet

I've been having this issue too. I tried a few different couches and with all of them I get the Uncomfy buff. The current couch I'm using is a level 7 comfort. Makes it hard to do anything when my sim is always uncomfortable.

I also have every pack and no mods installed.

Hello! Had this issue arise again. Right now I am playing with a limited number of packs, so maybe this can narrow it down to what might be causing the issue? It started again after I readded the Spooky Stuff pack. Otherwise, I have the Holiday Celebrations pack, Outdoor Retreat, Get To Work, Luxury Party Stuff, Perfect Patio Stuff pack, Spa Day, and the Cool Kitchen Stuff pack. 

Hello, I have started having this issue too. I have no CC or Mods installed currently and my Sim is getting an Uncomfortable moodlet on an 800$ comfort 7 chair that he's never previously gotten that on. I've tried swapping out the desk he's sat at (500$ to 2100$) as well as the rug (40$ to 440$) and he's still getting the uncomfortable moodlet.

Edit: These are the packs I have:
Get to work, Get together, City Living, Cats & Dogs, Seasons, Get Famous, Island Living, Discover University, Cottage Living, High School Years, Life & Death, Outdoor Retreat, Spa Day, Vampires, Parenthood, Realm of Magic, Werewolves, Luxury Party, Perfect Patio, Cool Kitchen, Kids Room, Vintage Glamour, Toddler, Laundry Day, My First Pet, Tiny Living, Nifty Knitting, Crystal Creations, Everyday Clutter, Bathroom Clutter, Book Nook, Kitchen Clutter, and Holiday.

I just started playing again after taking a couple of months off. I’m having the same issue with the new loveseat from Royalty and Legacy, the Sovereign Shapes Loveseat. It has comfort level 5 and my sim is always uncomfortable when sitting on it. I tried swapping it out with the Desert Luxe couch Prime Luxe Plush Sofa which has comfort 7 and my sims’s discomfort level is increasing. Since this is a $950 couch, I would expect it to be extremely comfortable for her, but nope
