Like everything else these days, you can order your next mattress online and have it delivered. But if you’re concerned about choosing one without trying it out, Consumer Reports does a number of mattress tests so you can find exactly what’s right for you. In Consumer Reports’ most recent member survey, more than 40 percent of members said they bought a mattress online in 2019 and 2020. Perhaps more reassuring, only about 2 percent of surveyed members said they were dissatisfied with their online mattress shopping experience. Many online mattress retailers offer free shipping and generous trial periods, usually 100 days or longer.
