Who will be your guests? I can't imagine the need for 2 queens. People who are used to sleeping together in a king would appreciate the king and you have room for it. If the other queen is intended for a child or two of the couple in the queen, then I'd keep the king and add a twin trundle bed or a set of bunk beds where the sofa is to accommodate kids needing to share a room with the parents. I can't quite imagine two couples sharing a guest room, needing two queens. edited to add...the wall color is beautiful! And maybe I misunderstood your question...are you going to add two twins like the inspiration and just used the queens for a visual? If you'll be hosting adults in that room, many couples want to sleep in the same bed.

Who will be your guests? If you're stuffing lots of people in a slightly too small cabin, 2 queens is better than a king.

2 queens offers more versatility.

Full vs queen get the queen everytime!! King=OVER KILL IMHO. If you will have singles/children I would go for twins /bunk beds--two sets-- pack them in.

I can’t imagine 4 adults being comfortable sleeping in a room that size, so I would do 2 doubles. That gives you a bit more space between the beds and you can put in a proper chest of drawers for more storage.

Of a Queen and a single, if you expect to sleep one couple and a kid.

Two same size if they fit. Two queens is hotel like so works for families visiting with kids.

This all depends on who your intended visitors are. Can you say more?

I've had 2 queen beds in a guest bedroom and it worked perfectly to accommodate different number of guests, singles, doubles, families, etc., they simply used the number of beds they needed.

I married into a family that owns a mountain cabin. Two queens!!!
One room of the cabin has two queen beds. In a 4 bedroom cabin and 6 kids, now adults and married and towing grandkids with them, the two sisters and their husbands used the two queens room. When my family outgrew the double bed room, we moved to the two queens room. It was perfect for us and our two kids. When my daughter, now a teenager brings a friend to the cabin, they each take a bed.
It offers great versatility and gives you options.
Go for the two queens.

It really is about the make up of your family/ visitors. I can't imagine putting two couples in one room--doesn't matter the bed size. Kids will always share a room with one another. Asking unmarried people to share a bed isn't a thing. My bff adult daughters won't even do that anymore. One will take an airmattress on the floor before sharing a bed.

I would do two queen beds and two chairs that open up two twin beds. My husband and I are so use to being in a king that when we had no other choice at all hotel, we each took a queen and put a child on the pull out. Very versatile.

I needinfo as to who you are planning this for. I agree not ideal for more than a family so I need info. We had a cabin at the lake it had 2 bedrooms and a big attic , us kids slept in the attic of foam pads and sleeping bags it was fun when we were young no so much as we aged

one king with a roll out sofa or two roll out twin chairs.

Doesnt look like there is room for 2 queens. do two twins or one king

The inspo pic is twin beds , you do not have space for 2 queens since the access to the beds is only from one side alwyas bad design . I will wait for answers to our questions

Look at the picture posted by OP of the actual subject room with 2 queen box springs. Both beds are up against the walls, so whomever sleeps next to the wall will have to scoot down to the foot of the bed or climb over the other person to exit the bed if needed (use the bathroom at night, wakes up early, etc). Also, the space between the beds is tiny; where would clothing for 4 people be stored? Is there a closet?

With a Queen and a single, you can walk around both sides of the Queen and still have more space between the beds.

There are 3 bedrooms—a giant one with a king, a normal with a queen and this giant one ( the room is very long as well with closets when you walk in and enough room at other end for couch or dresser . We have adult kids and friends who will be using. Curious about chairs that open up to twin beds! Link?
I get that there is not a lot of room to get out of bed if 2 queens…. Just trying to maximize sleeping space….but if that is dumb…??? The inspiration photo was for colors, not twin beds…..

I will be the odd person put and say a queen plus built in bunks - with deluxe xl twin matteresses, phone plugs ins, reading lights and high end linens - togetherness is under-rated :)

You don't show the sofa wall but perhaps one of the beds could go there?

Just google chairs that become twin beds. Read reviews and pick one😁

Here is an interesting way to handle multiple guests.

This is called a Twin over Double/Queen L Shaped Bunk Bed
