For a color palette to be harmonious, there’s no need to match everything in an obvious way. These bar stools coordinate really well with the kitchen island and the whole décor in general. The seat is a combination of white and gray which are also the colors used throughout the room.
A backrest tends to be more comfortable. If your bar stool is in an area you’d like people to stop and stay awhile, this is definitely an option to consider. Just because a bar stool is designed without a back doesn’t mean it will lack comfort. Plus, stools without a back can be space-savers, tucking neatly under the countertop.
In addition to the height of the stool another detail to take into consideration is the spacing between them. There should be 26-30” from the center of one stool to the center of the one next to it. This ensures a comfortable seating experience for all the users.
Wood, plastic, fiberglass. What your bar stool seat is made of can be anything, really. Not that this fact makes your decision any easier. But if you’re stuck, think about practicality if you want to be able to wipe it clean, something non-upholstered might be the way to go.
