Material choice will determine how long your bar set lasts and how well it can resist the things that threaten most furniture at home: humidity, direct exposure to liquids, and normal wear and tear. Let's take a look at the best available choices.
Hardwood
If you're thinking about longevity, then hardwoods are the best possible bet for you. Hardwoods are naturally resistant to humidity and temperature changes, which are the most common household threats to wooden furniture.
Hardwoods also handle direct exposure to liquids well, especially once they are properly and regularly treated. So, you won't have to worry too much about spills or poorly used coasters.
Manufactured Wood
Manufactured woods are inferior to hardwoods when it comes to longevity, but because of how much cheaper they are, you can find them available in combination with more materials and in an arguably wider array of style options.
Avoid medium density fiberboard where possible since it struggles against humidity and water. Manufactured woods with a solid wood core tend to fare better as regards longevity.
