Couple on a king size divan bed - What is the best couple's mattress?

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 heavier couples is one with excellent bounce back, and firm support to ensure proper spinal alignment as you both rest. On the other hand, 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.

the effects of sleep deprivation on couples

So, why is it important to find the best mattress for you and your partner? Essentially, without the proper support and comfort for both of you, you’re less likely to be able to fall asleep and stay asleep, likely causing you to be sleep deprived. 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 that 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, and potentially rid 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.

what is the best mattress for couples?

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. Or our just snug collection combines indulgent memory foam with proper spinal alignment.

what is the best 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 the room. It’s important to be comfortable while you sleep, and that often means having the space to reposition or spread out a little.

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

what is the best mattress for overweight couples?

The best mattress for heavy couples is one that has a good bounce back. Our Miracoil® range offers support through a uniquely designed spring system that runs across the entire mattress for enhanced bounce back and spinal alignment, making it one of the best motion isolation mattresses for couples looking for undisturbed sleep. If still unsuitable, opt for a firmer mattress to ensure proper support for the both of you.

what is the best mattress for couples with different weights?

When it comes to being a different weight to your sleeping partner, you’ll want to find a mattress with a happy middle ground in comfort, support and pressure relief so nobody has to compromise (too much). Hybrid mattresses are a fantastic option as they offer a balance of support and comfort, and we’d recommend a medium-firm option with zoned support.

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. Unfortunately, sometimes 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.

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 for both of you. In the 1980’s, we launched the Miracoil® spring system, specially developed to eliminate ‘roll together’ - the uncomfortable experience of rolling into each other during the night 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.

what is the best cooling mattress for couples who sleep hot?

As mentioned above, the UltraGel™ range is a firm favourite for hot sleepers, but we also have our Memory Cool™ collection, which is innovatively infused with graphite to transfer heat from the body. It’s foam structure is 15% cooler than standard memory foam, so you get the same body contouring and pressure relief without heat staying trapped.

are latex mattresses good for couples?

We’ve spoken about memory foam being a good mattress base for couples sharing a bed, but what about latex? Latex is another great option for sleeping with a partner as they naturally isolate motion, offer excellent breathability, even when sharing a bed, and are naturally hypoallergenic if one, or both, of you suffers with allergies.

what is the average lifespan of a mattress for couples?

If you choose a suitable mattress for both of your needs, especially in terms of weight and sleeping position, you can expect to get 7-10 years out of your mattress still, depending on maintenance and level of use.

what to consider during your couples mattress purchase

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
