The first thing you should do when choosing the best swivel tub chair for you is to learn as much as possible about tub chairs in general. Be able to recognize the style and shape of the chair, and decide early on what type of upholstery you want for your chair. Leather will be more expensive than other types of upholstery, and certain types of leather can be more expensive than others. If you do not want leather, choose a color and pattern, as well as material, for your swivel tub chair that will suit your needs well.
Once you have determined what type of upholstery you are looking for, you may want to take some measurements in the room in which you intend to place the swivel tub chair to find out how much space you have to spare for the chair. Consider the placement of the chair carefully; you will want to choose an area of the room in which the swivel function will not go to waste. Figure out what size chair you need and narrow down your search from there. If you are considering a leather swivel tub chair, be sure to research the pros and cons of high-grade leather versus lower-grade leathers that will be less expensive.
If possible, be sure to sit in the swivel tub chair for a fair amount of time before purchasing. This will allow you to focus on the comfort level of the chair as well as the construction of the unit. Pay special attention to the swivel unit's function; make sure it moves smoothly, does not squeak, does not thud or otherwise move in unnatural ways when you shift the chair around, and it is stable in all positions. Take a look at the seams of the chair as well to make sure they are strong, well-sewn, and discreet if applicable.
The swivel tub chair you choose should fit with the overall decor of the room in which it will be placed. While this is largely a matter of preference, be sure to choose a chair you will be pleased with for several years, even as common furniture trends change and styles shift toward different colors or patterns. Most people will want to avoid loud colors and busy patterns, but for some people, such a chair would work well as a conversation piece or focal point in a room.
