What is a “mattress in a box”?

In the last few years, the “mattress in a box” industry has become very popular and many people are choosing to buy a “mattress in a box” online verses going to a retail store and picking a mattress on site, where you only have 10 minutes to try out a mattress. Mattress in a box companies sell their mattresses almost exclusively online and then ship them in a box. This means that there are no extra costs for big showrooms, commissioned salespeople, or expensive shipping costs. These savings are then passed on to the consumer, who gets a quality mattress at an affordable price, their prices are much cheaper compared to traditional mattress companies.

Another big reason why these mattresses are so popular, is because they come with 100 night trial. This means that if for some reason you’re not satisfied with the mattress, you simply need to contact the mattress company during the 100 night trial and they’ll arrange a free pick up and refund you the money.
