There are lots of interesting, comfy chairs, bu tit's hard to advise without knowing what you like. Here are some random thoughts: They look like IKEA chairs. i also really like IKEA Henriksdal. They're quite big, however, some with a wide range of slip covers. From strictlysimplestyle.blogspot.com

Me again, Tammy. Thanks for sharing all the photos of your cozy home. If you like it the way it is, just enjoy it. If you're wanting a more modern look, start two Ideabooks on Houzz, one "Transitional" and one "Modern Farmhouse." Save photos of houses you like that seem realistic with the style of your house--the "bones" of it, and what you already have. Look up something called "negative space." Here's an article on it in Houzz. It's about the nice sense of space and flow you get when your eye can rest on empty space. Not every wall has to have some little object on it. More space means you focus on a few nice pieces, an art work, some photographs, plants, etc. so your eye doesn't get too overwhelmed at taking in too many small things. That's why I suggested removing your metal shelves in the dining room to focus on your lovely hutch, whether it has a top on it or not.

Comments on your photos: --The bathroom is really nice--great paint choice; not too many knick knacks; nice shower curtain. --Sun porch: take off everything from the walls behind the corner wicker chair. If you want, add a little modern-ish reading light over the chair to suggest a cozy reading corner. One pillow--tops-per chair! How can you sit down otherwise? --Daybed/office room. If budget allows, a simple blue tailored print or solid cover would work better than the ornate spread on there now. Get a nice horizontal painting for over the daybed and remove the other little painting entirely and take off the metal thing. --Bedroom with brown tufted headboard. Hang the mirror and get yellow and blue curtains with coordinating yellow and blue shams and bedding. --Den with big brown couches. Move the sofas about a a half foot from the wall to add some visual space to the room. Move the the horse art to the window wall with nothing else--zero. That way, they'll be the first thing you see when you enter the room. Get a ledge shelf for the other wall and arrange JUST A FEW PIECES YOU LIKE ON IT! Negative space is a positive! Get a round tray for the ottoman in an accent color and leave it empty for people to put down drinks, food, etc. No pillows would be better than the floppy oversized ones on the couch that just look kind of sloppy. Less is more. --Fireplace room and everything that can be seen looks nice. If you have doodads hanging elsewhere in that room, take them down, so the focal point is that lovely fireplace. --The big bedroom. Move the mirror elsewhere. Center the dresser. It'll have more impact by itself. Again, doodads off the walls. Remove the little chest from the window. It's just another piece of visual clutter. You want a sense of the windows and light uninterrupted by that piece. Get some great curtains for this room and bedding that goes with them. With all the bitty things removed, these full curtains, hung very high and right to the floor, will have an impact. So will your nice bedroom furniture.

Teal/aqua will be great in the kitchen! What you choose will depend on what you want to put out. I would start with a mat by your sink. Then perhaps a piece of art on the piece of wall to the left of the sink. It looks like that is over a peninsula, is that right? Then find some coordinating dish towels. Places like Target have beautiful kitchen items. Bring some home and return the ones that don't work. You can find stripes, plaids, solids, and florals. If you want more, you could swap some of the stainless items on your counter for more colorful versions. Take it a little at a time just to see how it looks. Different people have different tastes in the amount of pattern and color they like. Have fun!

RL Relocation's suggestion is probably more elegant in a modern design, but my first thought was swag pendant. You'd need hooks at the various locations you might want them to hang. These are typically plug-in lamps, which means extra dangling cords. You can adapt a plug-in pendant to be hardwired and swag it from the canopy, or buy a hardwired pendant with a sufficiently long chain or cord and do the same. I'm not sure how feasible that approach would be with your model layouts. https://thediyplaybook.com/spray-painting-a-light-fixture-black/
