Backless barstools have pros and cons. I have a brief list of the pros and cons of this type of stools. This list is by no means exhaustive. You will likely have your own reasons for liking or loathing backless barstools. Please feel free to add your own reason to the comments section below.
Pros
1. Smaller than those stools with backs. These stools fit better in small spaces. The lack of back lends the stool to a less intrusive look.
2. Cheaper. Some backless bar stools are very reasonably priced. Bar stools without backs are constructed with less materials and are accordingly less expensive
3. Adjustable height seat. Many of these stools have adjustable height seats. These are very useful for people working at drafting tables or easels.
4. Durable. Often the backs of barstools are the most vulnerable part of the stool. The absence of a back means there are fewer weaker parts.
5. Lighter and easier to move. These barstools are easier to move when sweeping and cleaning up.
Cons
6. Comfort. Backless bar stools provide no support for the back. This is very important if you or your guest will be expected to spend longer periods of time seated in the bar stool. In addition, this type of stool is rarely upholstered.
7. Stability and security. This generally only applies to children, people with poor balance and drunk people. The lack of a back can possibly lead to falling off the bar stools. For some there is a bit of a stretch to get up on the stool. A back provides a sense of security.
As you can see there are a number of different pros and cons to consider when deciding whether a backless barstool will meet your needs. I will try to update this list from time to time and I would love to hear from you about what you think the pros and cons of backless barstools might be.
