Buying a mattress online has exploded in popularity in recent years. Hybrids are no exception to this trend. Some mattress retailers offer both in-store and online options. Others only feature mattress in a boxes. Don’t worry, there are tons of high-quality mail-order hybrids to choose from as you shop. The fact that your bed comes in a box is not an indicator of its overall quality. To get a good sense of your hybrid’s quality, take a look at things like certifications, construction, materials, and reviews rather than how it’s shipped.
