I did that in my guest room - no problem at all. The carpet is pretty low pile and the rug is a fairly thick sculpted type oriental. I have no pad under the rug. I also have a very short, dense wool oriental rug on the carpet in my living room. That also works fine. I have all these rugs on carpet because I moved from a house with wood floors to one with more carpet. I hope to get rid of the carpet someday when I feel like moving everything again. So then I will need the rugs and in the meantime I can't stand the plain beige carpet. In another room I have a thick wool runner that covers the width of carpet from the deck door to the wood floor in the dining area. It has no furniture on it that holds it in place so it ripples a bit. I need to find a way to keep it flat.

I would do small rugs on either side of the bed and do an area rug in the large area centered on the window and I like that placement for the bed it allows for a nice sitting area that is visible when the door happens to be open

Yes, she did paint the entertainment center, @Fun2BHere. Here is a picture from just before they moved in that she sent me. I’m not sure what they are going to use it for. I don’t believe they are going to put a TV in it. There is a TV over the fireplace in the hearth room, one upstairs in the playroom, and another outside in the outdoor living room. She says 3 TVs are enough for any house! Notice, she also replaced the beige ceiling fan with a white ceiling fan. I’m not a fan of ceiling fans, but we are in the south and they are often useful. As soon as the hardware store opens this morning, I’m calling to order knobs for the doors below the shelves. She’s still undecided on what she wants on the entertainment center doors. I think large heavy brass rings would look good. She’s thinking no hardware with push-to-open latches. Thanks for the links to the hypoallergenic rugs. I see that jute is supposed to be a good choice for allergies to dust mites. A neighbor had a jute rug in her living room. I loved it! It was so soft! I have seagrass in the breakfast room. It doesn’t bother me to walk on it barefoot, but there are other family members who moan and groan if they forget their slippers.

I’d layer some. Iirc, you like the boho/Scandi aesthetic? It’s not only an interesting look, but very cozy. Love the idea of Persians, tribal, cowhide, and woven as shown in first pic. Hopefully, ilikefriday sees this, she did layered rugs in her boho bedroom. Looks great. . If that’s not an option, I think I’d try a 5x7 in that part, or another 8x10. .
