A good strategy is to pair white with more white. So if you have a kitchen with white cabinetry and a white island, then perhaps a set of white bar stools would be the right choice in such a case.
The same shape of base with an upcycled metal seat makes for a rustic bar stool that would still be an appropriate addition to a modern space. The colored seats are perfect for mixing and matching. Round bar stools can take on a retro feel when they are outfitted with an old-fashioned seat, foot rail and pedestal base. These were found at Finch, in Hudson, New York. The vintage look would fit well at a traditional style bar or at a rustic or modern kitchen counter.
Green Gables Furniture has this Steel Traditions Crestone Swivel Barstool that features leather seat. Lapped seams across the cushion add strength and the old-fashioned steel base has a characteristic round foot rail. A little color goes a long way in enhancing the wood of these rustic bar stools. Perfect for a rustic, industrial or casual living space, these seats from Horizon Home have a subtle streak of green that adds a reclaimed feel to the pieces.
Leather furniture is usually something you incorporate in a traditional interior décor, unless the design is unusual and innovative, in which case it can easily fit in a more modern space. In the case of leather bar stools, the designs are not as versatile as for other material combinations. They tend to look more robust and they usually fit well in spaces that have an overall traditional and elegant design.
