Logan didn't need comfort. He never had. He remembers all the time he spent living in forests when he needed to isolate himself for a while. Anything worked for him, really.
Wolverines can sleep pretty much about everywhere. So, the first couple months after he moved in with Wade, he'd just crash on the couch. Sometimes, Wade would awake in the morning to see Logan sprawled on the floor and snorting after probably falling off the couch in his sleep.
He tried many times to convince Logan to sleep with him on his bed, but he always refused. Wade got that couch on a goddamn dumpster, and it couldn't possibly be comfortable to spend nights on.
So yeah, maybe he wanted to have a big gruff Wolverine laying next to him on his bed, but he also cared about him being comfortable.
He wanted it to be a home for Logan, even if it was a really small crack apartment.
Wade googled about Wolverines and how they nest, and he realized that Logan didn't really have much. He didn't have anything, really, since he dragged him here from a whole other universe.
So he would buy pillows, blankets, and plushies for Logan. And the grumpy idiot would pretend to hate the little hello kittys fluffy miniatures, but one day Wade's heart almost fully melted when he woke up in the middle of the night for a midnight snack, and catched Logan sleeping with all the gifts he gave him all around him, wrapped in a blanket with red and yellow heart patterns.
Sometimes Wade would awake hearing grunts and screams, rushing to the living room to see what was wrong only to find Logan trashing in his sleep, probably deep in a really bad nightmare, his body sweaty and brows furrowed. He looked in pain, and it broke Wade's heart. He imagined the terrors Logan was probably reliving in his mind.
When the sun hits Logan's eyes and he opens them, he feels slightly lighter. As if he's body's relaxed for what felt like forever. He looks around and doesn't see the usual living room, and he realizes that he's in a bed. Wade's bed. Wade isn't here, but all the blankets, pillows, and plushies are still all around him.
"What the fuck..."
"Morning, peanut!" Wade announced with an excited tone as he entered the room wearing an "Kiss the cook" apron and toasts on a plate along with a mug.
Logan gives him a confused and annoyed look. "Did you- Did you carry me over here in my sleep?" He asks, incredulous. His bones are fucking made of adamantium. He weighs like 300 pounds. And how the fuck did he not wake up?
"Yes, princess. Bridal style and everything. Only the best for my baby girl."
"Wade-" Logan warns through gritted teeth.
"Alright, look, I just couldn't take you looking so uncomfortable anymore. Besides, you got so peaceful after I put you here. You can't really complain."
"I can, and I will. I told you not to bother. I don't give a fuck about comfort."
"Well, I do. Now get a break on being all grumpy, I made you breakfast." Wade offers Logan the plate with toasts and the mug with black coffee, the way he likes it.
He just grunts and accepts it.
The next nights, the lumpy couch remained empty. Logan would slip into the covers with Wade, the pillows and plushies all around them, and Mary Puppins layed on their feet. Wade was wearing a Spider-Man themed pajamas, and Logan was in his boxers and one of Wade's silly shirts with an unicorn printed on it.
"We look like such a happy family!" Wade says in a dreamy tone in the middle of the night, the room dark as he lays face to face with Logan.
"Shut up. Go to sleep." He groans, eyes closed.
"Sweet dreams, peanut. I know mine will be. You're always in them. God, I had one these days where you d-"
"Go. To. Sleep."
Some mornings, they would wake up tangled, arms over chests, legs over legs, so close they could feel each other breathing. Sometimes, Logan would wake up first, and when he opens his eyes to see them tangled like that as Wade was in deep slumber, he just smirks and closes them again, drifting back to sleep.
After that, he noticed that the frequency of his nightmares was getting lower. But whenever he'd have them, eventually, Wade would always be right there next to him to comfort him back to sleep.
