  • The best mattress for couples is one that offers you both ample support, while preventing ‘roll together’. You should opt for the largest size you can fit in your bedroom, and a hybrid variation to ensure both of your sleeping preferences are met.

  • The best mattress for overweight couples is one with excellent bounce back, and firm support to ensure proper spinal alignment as you both rest.

  • Shorter and lighter people should opt for a softer mattress to prevent strain on muscles and joints.

As a couple, shopping for a mattress can feel like a minefield. We try out a dozen mattresses only to find that we have different needs to our partner, so a compromise is needed. After some debate about which is best, we settle for ‘good enough’, setting ‘perfect’ aside as a pipe dream. If this sounds familiar, or you’re simply tired of your partner waking you up as they move during the night, you're in the right place.

Let’s explore how opting for the wrong mattress can affect how you both sleep, as well as come to a clear conclusion on which is the best mattress for a couple.

effects of sleep deprivation on couples

Sleep deprivation not only negatively affects your health, but it can also impact your relationships. It’s common knowledge that lack of sleep can make us irritable and more emotional than usual, so it’s no surprise frequent lack of sleep can lead to relationship troubles.

What’s more, sleep deprivation can wreak havoc on many aspects of our lives, including our sex lives. Couples often find that when they're sleep deprived, they have less energy and desire for intimacy. But did you know that the right mattress can help improve your sleep quality?

Investing in a good quality mattress will immediately increase your comfort and support, while also ridding of any aches and pains that were caused by your old one. And with this fresh lease of life, you’ll likely reignite the fire in your sex life.

The best type of mattress for couples will vary between couples and individuals. Ultimately, everyone’s sleeping preferences are different so it’s about finding a mattress that suits both your needs and also promotes proper spinal alignment.

If you both require a firmer support that still holds that luxurious sink-in feeling, memory foam mattresses will be your best bet. Or opt for a hybrid mattress, one that ticks more boxes than one. For instance, our UltraGel™ range offers targeted pressure relief as well as unmatched cooling properties. And our just snug collection combines indulgent memory foam with proper spinal alignment.

what is the best mattress for heavy couples?

The best mattress for overweight couples is one that has a good bounce back. Miracoil® support involves a uniquely designed spring system that runs across the entire mattress to offer enhanced bounce back and spine alignment, while also preventing you and your partner from rolling into each other for an undisturbed sleep. If still unsuitable, opt for a firmer mattress to ensure proper support for the both of you.

the best mattress for couples with different preferences

Everyone has different needs when it comes to sleep. Sleeping together means combined body heat, disruptive movements, and limited space. Prime factors that can all contribute to your ability to achieve optimal rest. One person’s comfortable is another person’s sleepless night.

While traditional mattresses have come a long way for couples, sharing one mattress firmness between a couple with different body types isn’t perfect. So, we conducted a study to explore how many different sleep needs were found within couples.

study on bed sharers

According to our study with UCLAN, there shouldn't be a one-size-fits-all approach to mattresses as “contrasting body types need different levels of support to improve overall spinal alignment”. This improved alignment allows your spine’s discs to rehydrate, and muscles to relax throughout the night.

The study goes on to say that those with a higher body weight need firmer support. The same goes for taller people, and people with a larger hip circumference. On the other hand, people on the shorter, or lighter side require softer support.

what is the most common mattress size for couples?

For two adults, we always recommend choosing the largest bed you can fit in your bedroom, while still having space to move around each side. It’s important to be comfortable while you sleep, and that often means having the space to move around or spread out a little.

A double should be the bare minimum, but the sweet spot is super king. This size of mattress provides the most spacious sleep, giving a full single bed’s width to both of you (180cm).

the best mattress for couples who toss and turn

New technological developments have led to a better sleeping experience for you and your partner. It’s no longer just simple spring units and stuffing; a lot of smart developments now go into making the perfect mattress. In the 1980’s, we launched the Miracoil® spring system, specially developed to eliminate ‘roll together’ - an uncomfortable experience you’ll have when sharing a cheap mattress. The old solution was two separate beds, but let’s face it, who wants a gap?

Both our Miracoil® and Mirapocket® spring systems are designed to give extra support in the places we need it most and offer motion isolation to help prevent us from waking up our partners when we’re having a rough night. That’s one great step toward a perfect couple’s mattress.

mattress tips for couples

As mentioned, we know one of the biggest problems couples face when buying a new mattress is that their bodies are different. When choosing a mattress for couples, consider factors such as motion isolation, firmness preference, and edge support. It’s understandable that each partner may need a different degree of firmness so communication and compromise will play an important part in finding the perfect mattress that suits both your sleep needs.

sleep trials & exchanges

Our sleep trial is a risk-free way to try out the mattress in the comfort of your home to make sure you’re completely happy with your decision. If you decide within the sleep trial period that the mattress is not right for you, you can typically arrange the return of the mattress in exchange for a different mattress.
