When making a major decision, people often say you should sleep on it. That's exactly what a mattress sleep trial allows you do. You get to test your new bed over weeks and months to work out whether it meets your sleep needs. If not, you can return your mattress and get a refund.

Sleep trials save a lot of time, money, and stress when you're shopping for a mattress online. If you can't make it out to a mattress showroom, you can make your own at home with a mattress sleep trial.

As H&G's resident sleep writer, I lead a team of expert testers in the search to find the world's best mattress. We conduct all our testing from the comfort of our own homes, during the mattress sleep trial period. I can teach you how to make the most of your mattress sleep trial and what to do if the bed isn't right for you.

Mattress sleep trials − what you need to know

Before we begin, it always helps to define our terms. I spoke to mattress manufacturers and sleep specialists to find out how a mattress sleep trial works and which brands offer the best deals.

A mattress sleep trial is a period of time, set by your mattress manufacturers, in which you get to test your mattress in your home before you commit to your purchase.

According to Sleep Number's Lori MacLachlan, 'a mattress trial is crucial when shopping for a new bed. If you don't like the bed or find it's not the right fit for you, you can return or exchange it without hassle. Many retailers offer trial periods and generous return and exchange policies, so be on the lookout when you're shopping for a new bed'.

Ever the saleswoman, Lori is quick to clarify that 'Sleep Number includes a 100-night trial for smart beds, so you are able to determine if the bed is the right choice for you'. If you're not happy with your mattress, then it's time to get in touch with the manufacturer and request a refund. They'll want to know what didn't work for you, so that they can suggest different mattress types to better meet your needs.

As a professional mattress tester, I'd say that 100 nights is just enough time to test your bed through several seasons, paying special attention to its thermoregulation. If you're an indecisive shopper, and you know you need longer to make up your mind, then you should look for a longer mattress sleep trial. The best brands offer up to 365-night trial periods, which works out to a whole year of mattress testing.

What are the pros of a mattress sleep trial?

The mattress sleep trial is one of the best bits to come out of online mattress shopping. In the absence of an in-store showroom, you get to take the bed home and test it for yourself over a longer period of time. Instead of sitting on the side of the mattress for 10 minutes, you get to break in your new bed over weeks and months. You get a much better sense of your relationship with a mattress when you conduct a mattress sleep trial.

The longer the sleep trial, the more rigorous you can make your mattress testing. Here at H&G, we score each mattress against the same criteria: comfort; support; breathability; motion isolation; edge support; and the all-important price. We test each bed for several months before we write our reviews in order to allow the mattress to adjust to our unique sleep needs. It's worth learning how to test a mattress at home to make the most of your mattress sleep trial.

What are the cons of a mattress sleep trial?

Let’s clear up a common misconception. Mattress sleep trials aren't really 'try before you buy': you'll need to pay upfront for your mattress before the sleep trial begins. You'll only receive a refund if you return your mattress within the window specified by the manufacturer. Before you buy, make sure you read the terms and conditions: for example, some brands will only accept your return if you've covered your bed with the best mattress protector.

Not all mattress brands refund 100% of your money at the end of a mattress sleep trial. For example, Saatva deducts a $99 shipping fee, while Nectar charges for their White Glove service and state-based recycling fees. Again, it's so important to double-check the terms and conditions of your purchase before you buy.

Some mattress brands offer free perks, such as sheets, pillows, and bed frames, when you buy their mattress. These freebies might not fall under the provisions of your mattress sleep trial. That means the brand could choose to deduct the retail price of those products from your return, leaving you further out of pocket.

I asked mattress salesman Andy Bloom to tell us more about the practicalities of mattress sleep trials. 'Some companies may pick up the mattress from your home, while others may ask you to ship it back. Return policies vary widely, so it's important to familiarize yourself with the specific terms and conditions before making a purchase,' explains Andy.

'Although offered with good intentions, the mattress trial ultimately contributes to increased costs for consumers,' says Andy. 'The expenses associated with handling and disposing of returned mattresses, as well as the potential loss of revenue from reselling them, all contribute to higher prices.'

Plus, there’s an environmental impact. When you return your mattress to the manufacturer, there's a high probability that it will end up in landfill, where a single mattress takes thousands of years to biodegrade. If you're keen to shop sustainably, but you still want to take advantage of a mattress sleep trial, then I suggest you look for brands that donate or recycle old mattresses.

Mattress sleep trials FAQs

What should you look for during the sleep trial period?

Pay attention to changes in your sleep: the right mattress will strike a careful balance between comfort and support. It should keep you cool and dry and bear your weight to ease your aches and pains.

Notice any changes in aches and pains: when you buy the right mattress, you should start to experience relief after a few weeks. New aches are normal in the initial adjustment period. If you're still feeling achy a couple months in, then it could be an indication that your mattress is too soft or too firm.

Consider the quality: within the first months of use, a good mattress should show little to no aging or sagging. Apart from feeling softer and more adapted to your body, your bed should still look and function like a brand new mattress.

Can you end a mattress trial at any time?

No. Most mattress brands set a minimum, as well as a maximum, length of their sleep trials. Usually, you'll have to wait a full 30 days before you can return a mattress. That accounts for the time it takes to break in a new bed.

Final thoughts

When you're buying a new bed, take a careful look at the mattress warranty. Don't be overawed by lofty claims of lifetime guarantees − just look for something sensible that covers defects in materials and manufacture.
