The backrest has vital stylistic and ergonomic contexts in the selection of bar stools.
Low-back -- it supports the lumbar spine that is most susceptible to back pain problems caused by sitting postures. The L1 to L5 vertebrae get adequate support, and so does the torso. From the style context, their tall body gives the bar stool a contemporary look suitable for avant-garde bars with mostly young visitors. Wall graffiti is a frequent décor element.
Mid-height and full-height -- they support the thoracic spine and full spine, respectively. Their style concept is conventional, hence they will match the typical bar environments with heavy furniture, dark walls, and low-intensity lighting.
Reverse-arch -- this style supports the width of the back snugly, so you feel comfortable and relaxed even when you sit for a long time. This style is usually complemented by cushioned upholstery of leather or faux leather. It will suit the mid-to-upper segment bars with a plush décor.
Backrest-cum-armrests -- in this style, the backrest extends to the front and forms the armrests. These types of stools will go with mid-century modern interiors.
Molded backrests -- These come with the plastic bar stools. They're comfortable and will be perfect for minimalistic decors, spaces full of light and neutral colors.
