Why One Mattress Firmness Doesn't Work for All Couples

Imagine drifting off into a peaceful sleep, only to be jolted awake by your partner's tossing and turning.

If you're sharing a bed with someone, chances are hoarding the blankets isn't your only problem. Staying asleep and getting a good night’s rest can also be challenging if your mattress isn't designed with both sleep styles in mind.

Most couples struggle to find a mattress that's comfortable for both of them, and one of the biggest culprits is its firmness level.

Mattresses are generally categorized on a 1-10 firmness scale, with one being the softest and 10 the firmest. While some couples can find a middle ground that works for both of them, it's often not ideal for either partner.

A mattress that's too soft can cause discomfort due to excessive sinkage, while a mattress that's too firm can make it difficult to get comfortable and lead to pressure points..

Let’s look at the top reasons why one mattress firmness might not work for all couples.

Body weight and size

When it comes to mattress firmness, consider how much weight you and your partner bring to bed – literally!

Heavier individuals will require more support from the mattress than lighter sleepers, so firmer mattresses may be the way to go.

Couples with a big weight difference should consider this factor when selecting a firmness level. Otherwise, one partner could feel like they’re sleeping in a “dip” or being pushed up by the other partner.

As well someone that is lighter may feel a certain mattress is firm well someone bigger might think it is medium. Body sizes make a huge difference on how a mattress will feel between couples.

Sleep positions

Matching mattress firmness to both your sleep positions is crucial for finding the right balance of comfort and support.

A soft mattress may be great for side sleepers, as it can provide cushioning and contouring around the hips and shoulders. Back and stomach sleepers, on the other hand, will likely require a firmer mattress to keep their spine properly aligned.

However, regardless of their sleep position, some people may be better off with something in between – not too soft or firm.

As a rule of thumb, side sleeps tend like surface softness and comfort, well back sleepers would be a bit firmer. Stomach sleepers tend to be on the firmer side of back sleepers.

Sleeping habits

Depending on how much movement occurs during sleep, a softer or firmer mattress may be needed to keep both partners comfortable throughout the night.

If one partner is restless and moves around frequently, then a firmer mattress may be better suited to keep them from sinking too deep into the bed. On the other hand, if both partners stay relatively still during sleep, a slightly softer mattress could provide more cushioning and comfort.

If motion transfer from a restless sleeper is causing a disturbance to your sleep think about staying away from traditional coil mattresses and lean towards pocket coils or an all foam type of design.

Underlying health conditions

Whether you suffer from chronic pain or the occasional ache, a mattress that's too soft or firm can worsen existing symptoms or cause new ones.

Someone who has chronic back pain, for example, may require a firmer mattress to help alleviate pressure on their spine. But those with neck, shoulder, or hip pain may find more relief on soft to medium mattresses that can provide contouring and cushioning around these areas.
