Buying a mattress online may seem a little daunting at first. But once you see how easy purchasing a new bed from home can be, you'll never want to go to a mattress store again. The best online mattress brands offer high-quality beds at an affordable price, ship them right to your door, and often throw in discounts and freebies with your purchase. Just be sure to consider policies like sleep trial, warranty, and shipping and returns, so you can buy with confidence.

To say there's a lot of mattresses to choose from online is an understatement. To put you at ease, the testing pros at Mattress Advisor selected the best of the best and put them to the test to help you pick out your new online mattress.

Our recommendations:

What to consider before adding to cart

Sleep trial

Most online mattresses come with a risk-free trial period, so you can sleep on your new bed and still return it for free (or at a low cost) if it isn't the one for you. It takes up to 30 days to break in a mattress and see if it works for your sleep style, so make sure to take advantage of the full trial period before making any final decisions about your new mattress. 

Warranty

A mattress warranty is a promise from the company to refund or replace your mattress if it has any physical defects outside of normal wear and tear within a certain time period. The length of a warranty is a good way to gauge the quality of a mattress, so look for a bed with at least a five- or 10-year warranty to make sure that you won't have any issues with your mattress in the near future. 

Shipping and returns

When it comes to mailing, most online mattress brands compress mattresses into compact boxes that can be carried through narrow doorways and hallways. If you need extra help getting your mattress inside, some companies will move the mattress into your bedroom for you and remove your old bed for an additional fee. Many will even sweeten your shopping experience by offering free or low-cost shipping options and lenient return policies.

Foundations

Choosing the right mattress foundation for your new bed will help increase its comfort and durability. Box springs are the most popular mattress foundation and offer sturdy support, but they won't be supportive enough for some memory foam beds. Slatted platforms, meanwhile. offer increased support for heavier mattresses while also allowing you to use the space underneath the bed for storage.
