What are the differences between using quartzite vs. marble for outdoor sofa tops?

When selecting natural stone for outdoor sofa tops, quartzite and marble are two popular choices, each with distinct characteristics. Quartzite is highly durable and weather-resistant, making it ideal for outdoor use. It withstands heat, UV rays, and moisture better than marble, which is more porous and prone to staining and etching. Marble, while elegant, requires regular sealing to maintain its appearance in outdoor settings. Quartzite offers a wider range of color options and a harder surface, whereas marble provides a classic, luxurious look but demands more maintenance. For long-term durability and minimal upkeep, quartzite is often the superior choice for outdoor sofa tops.
