It is really possible for you to put the seating in your main bedroom since I believe that it will have wide enough space. At least, when compared with the other bedrooms in your house. Then well, since having the seating to your bedroom decoration will give you some benefits, so here, we do recommend you to use the space for sofa or chairs. Imagine that as a private space, you can do anything you want there. Including when you need to spend your time alone and don’t want to meet anyone, you can do your reading there, watching Netflix, playing games, just anything you want if you have the good facilities there.
For the seating choices, you can have it based on your taste or bedroom space. If you love to enjoy the scenery and you have the access to this in your bedroom, then you can provide the bench stick to the window. If you love enjoying tea, you can provide a sofa chair with a small coffee table there. In case you want to enjoy your time there laying or relaxing, you can have the sofa. Here are some recommendations that we have compiled for you. I wish there will be some ideas that you can adapt.
