The phrase "comfortable seats" refers to chairs or other seating arrangements that provide a high level of comfort and support for those sitting in them. These types of seats are designed with materials, shapes, and cushioning that make it easy for people to sit down, relax, and stay comfortable for extended periods of time. They may have features such as adjustable backrests or armrests, soft fabrics, and proper support for the lower back and legs. The goal is to provide a pleasant experience while sitting, whether in an office setting, at home, or in a public place like a cinema or airplane.
