The process of buying a new mattress can often feel like a daunting task.

'It can be easy to pick a mattress solely based on price or initial comfort; however, the biggest mistake you can make when buying a mattress is not taking your sleep position and comfort level into consideration,' says Elisa Regulski, a sleep health content specialist at Mattress Clarity (opens in new tab)

'You will have your mattress for 7-10 years, so it is important to make sure that it will support your spinal alignment and overall health,' the specialist explains – so it is important to get it right.

Elisa says that back sleepers should look for a mattress with an average firmness level (6.5-7 on a 10-point scale), meaning a medium-hard level of support is best if you fall into this category. 

'There are certain mattresses that are designed with side sleepers in mind, and others where the firmness level is better for stomach sleepers,' emphasizes Miranda Garibaldi, a sleep health content specialist at Sleepopolis (opens in new tab). However, stomach sleepers may need to consider an even firmer mattress. 'Stomach sleepers need more support, so they should look for a more firm mattress.' Elisa adds.

The majority of the population are categorized as side sleepers, but what kind of mattress should they choose? The experts suggest that plus and soft mattresses are best for side sleepers who hope to relieve pressure from their shoulders, hips, and knees. 

'Those with chronic injuries might also want to consider a mattress with pressure relieving properties, such as foam, to help reduce pain,' Elisa adds. 

If you categorize as a 'combination sleeper' (someone who alternates their sleeping position), then you may need to test your comfort levels to pick a perfect mattress for a good night's sleep. 'One great way to do this is by finding a mattress online with a sleep trial period, as it can take time to break in a mattress and determine whether it'll work for you,' Elisa says.
