It needs some window treatment for sure. I wouldn’t feel comfortable in this room at night.

A light colored, maybe fluffy rug would be great. Big enough so a person could walk from the bed to the armchair while staying on the rug.

The lamp seems quite small. Could the lamp + table (or whatever it’s on) be set so it’s accessible from both the bed and the chair?

Both the bed and the chair seem quite crowded with pillows and throws.

What is the long wood thing on the right wall? A bureau? It’s much too large for this tiny room.

Is that just a single bed ? I never like thows on furniture I always think there is yucky stuff being hidden. For sure not in a guest room.The wall colr is kind of depressing but maybe some art on the walls and for sure window coverings might make it work. The dresser is too much for a tiny guest room. Maybe either more pics or a to scale floor plan and a bit more info too

Your best way to achieve a mid-century modern look is to do some serious research and learn about the work of seminal designers from that era. Also, start saving up to buy genuine vintage pieces. Not all your furniture and decor has to be vintage (none of it does, I suppose, but I'm assuming you're as serious as I am about mid-century), but without at least a couple of vintage pieces it will be more challenging to reach your goal.

I've had good luck buying vintage from Etsy and eBay. I think it's harder to get good pieces that way now, thanks to both the popularity of mid-century and the general en-shittification of the internet. You need to be really careful to vet your pieces for authenticity. Other sources include Chairish and 1stDibs. If you are in an area with good antique shops, thrift shops, and/or flea markets, that can help.

I have also purchased from Design Within Reach. They are licensed to sell some newly made but genuine mid-century designs, and they also sell pieces from other, much later, designers that may fit in with the look you're after. They are not cheap; whoever came up with that name was (IMO) fooling no one but himself!

Don't overlook Ikea. The Poäng chair (for example) is a classic for a reason. The reason is that to some extent they ripped off a couple of other designers, but they made a good job of it, and it's more affordable than Aalto's Lounge Chair 406 or Mathsson's Pernilla Armchair.

Avoid West Elm for furniture. Sure, it looks nice in catalogs, but IME it's not well made. OTOH, some of their smaller, decorative pieces can fit in nicely. And on occasion they have pretty nice bed linens.

You definitely need a window treatment. A rug may well help, but may not be essential. I'd look into a different ceiling fixture, and maybe add a lamp or two. Your paint color may look terrific in real life. Judging from what I see on my monitor it's not a color I would choose, but since you like it, try to make sure that your window treatments and bed linens (and rug) work with it. It's the finished look that counts.

Lastly: Take your time. You don't need to have all the pieces of the puzzle right away. You'll get there eventually.

Honestly I think you are overthinking it. If this is a double set it up so each side is accessible and dress it as a bed not a sofa type area. Ditch the throw on the chair, get some window coverings, add some art above the dresser and maybe a plant and lamp. Done

Good advice already - I’d like fully lined bamboo blinds for this room - would add a lot of texture but not crowd the room, you need the lining as they are not private ar night

I’d def get a bigger lamp so guests don’t need to use the overhead light - def not cozy at nught

The wall color doesn't exactly say mid-century modern to me nor does the flooring.

@Norwood Architects makes an informed point. On the other hand, in the mid-1900s, not everybody put in a new floor—no more than they do today. There were trendy colors in the mid-1900s, and there were also widely available colors. Again, not everybody used them. I think you can get a mid-century look without every detail looking like it came out a showroom or a magazine ad in 1940–1970—which covers an awfully wide range of styles anyway. That's why I made the suggestions I did above re furnishings. One or two really good pieces can make a difference.

I think your room is too small for wood paneling, which is something I admire in other people's homes and have never wanted in my own. And I probably wouldn't use wallpaper myself. Both are legitimate mid-century options, but as you've just painted, you may not want to spend time and effort (and money!) redoing your walls.

For the heck of it, here are some articles on paint colors in the 1950s, and across eras.

If you can get access to magazines from the mid-1900s (libraries are good for this) you can see what people were designing and marketing then.

That ^^^ light fixture looks a lot like one I had in my bedroom when I was growiing up. And I'm vintage mid-century myself! 😉

we get no answers to questions there is another duplicate post maybe there

Celery, you nailed it!

I spent a lot of time thinking about what guests want in and actually use in a room:

Make a super active corner for storage and getting ready:

* Remove the chair. Guests will not sit in it and will only throw stuff on it. Instead hang hooks on the wall, likely where the chair is now. Guests LOVE a set of hooks.

* Place an ottoman or bench under the hooks between the dresser and wall. Guests can throw bags on it.

Practical decor:

* While I'd hate to cover the top of that beautiful furniture, throw some kind of long runner on it before guests arrive so they won't scratch it up or leave water marks.

* Hang a mirror above the dresser. Don't clutter the dresser with other decor. People want surface space.

* Get cordless blackout cellular shade in a color that isn't just white. No curtains. Too fussy. Guests can sleep in.

* Yes to a soft rug on the feet.

* Hang a plug in wall sconce with arm that they can pull over the head of the bed for lighting, or push out of the way.

* While nicely decorative, the pillow overkill is making your room feel smaller. Plus, where will all of those pillows go at night that won't be a tripping hazard and won't bury bags and personal belongings? I'd get three uniform white pillows for across the back. Use a throw blanket for your pop of color.

* Yes to MCM art above the dresser. Only soft fabric art above the bed.

Lastly, locate outlets and make sure there are enough flat surfaces nearby for charging. Save room for a small wastebasket and kleenex somewhere.
