1. RESEARCH LIKE CRAZY
A mattress is a big ticket item. Make sure you research beforehand. Talk to family and friends. Stalk the internet. Gain as much information as possible: comfort, support, durability, size, warranty, where to shop.
2. READ ONLINE REVIEWS
While asking your friends and family is a good start, read online reviews from hundreds or even thousands of customers on any particular mattress. People will be honest online and tell you what they like and don’t like. Then choose a a company that has mostly positive reviews, like Saatva. Their company was the best reviewed mattress brand on Google in 2013 with an average rating of 4.9 on over 2000 reviews.
