How Comfortable Are Chairs And Armchairs For Home Use?

I am going to my living room this afternoon. I see a new armchair near the window and a small chair at table. The armchair look soft and wide. I sit and it hug me a little. The chair is smaller and a bit hard. I feel curious because both look simple but feel different. Some threads stick out from armchair edges.

I am thinking why chairs and armchairs are popular now. People dont just use old wooden chairs anymore. I feel curious because some armchairs feel comfy but some sink too much or hard to sit long. Maybe material and size matter more than color. It make me wonder if all chairs and armchairs are same or some are really better for daily use and comfort.

I take my phone and start checking while scrolling many online marketplaces including alibaba. I see chairs and armchairs in many styles and sizes. Some small some big. Some soft some firm. Some plain some colorful. I read few reviews where people say some chairs feel perfect and last long others squeak or lose shape fast. It feel like picking right one really matter if you want comfy and easy seating at home.

Now I am thinking which chairs and armchairs are really better for daily use and comfort? Are small simple ones more usefull or big soft ones better choice?
