If you plan to buy a bar stool online, read on for a full overview of Amazon's four most popular bar stool chairs.

The Air Lift Stool by Winsome Wood

The Winsome Wood air lift adjustable stools are funky and cool with a stainless steel frame, black faux-leather seats and a curved foot rest that invokes the feeling of a modern barber shop. The stools typically cost between $175 and $225 for twos, a pretty good value for what looks like a designer model.

The seats have a metal foot bar to rest your feet and a side handle that allows you adjust the height of the stool. The one flaw in the design of these stylish stools is the minimal amount of padding in the seat. The stools are clearly designed for looks and not long-term sitting.

Valencia Eco-Friendly Indoor and Outdoor Bar Stools

These stools are made from selunsar wood, a dense hardwood that's known for its durability and fast regrowth rate. Selunsar also rivals teak for its strength outside, resisting the elements and standing up to inclement weather and the sun's rays.

Before they're built, the Valencia stools are painted with linseed oil, which both protects and treats the wood, ensuring long-term durability, but using an all-natural product. They cost between $90 and $120 for a pair, a pretty reasonably priced.

Overall, the Valencia eco-friendly stools aren't their top-of-the-line, but they're a great stool for the price and offer a unique look for a fraction of the price of teak.

Carolina Cottage Stool by Carolina Chair and Table

At the higher end of the price range are the Carolina Cottage Stools. They retail for around $200 for a pair, but come in four trademark colors - antique white, antique red, walnut and the most popular antique black. The stools also come in two sizes - 2 feet and 2.5 feet.

The stool comes pre-assembled direct from the factory where it's been handcrafted and built from high-quality wood. At a substantial 15 pounds, these stools are durable and strong and able to carry a fair amount of weight thanks to their reinforced leg braces.

Monte Carlo Leather Game Room Stool by VisionDecor Furniture

For anywhere from $300 to $400 per pair of stools, buyers are guaranteed a durable stool that's both fairly luxurious and strong. Weighing in at 20 pounds and over 30 inches high, the Monte Carlo Leather Stool is both impressive and substantial.

The primary drawback of this luxury leather stool are the arm rests. Some buyers might like them, but others may find them inhibiting or a nuisance rather than a luxury. Before you buy a full set of these bar stool chairs, you should try one out to see how you like it.
