Are you and your partner looking for a mattress that will stand the test of time? The Nectar mattress is possibly the best option for you. The Nectar mattress can hold up to 46 stone or 292 kg, which is one of, if not the most weight a mattress can withstand from our mattress reviews.

The mattress from Nectar is also a great option for couples because it’s nearly entirely from memory foam which is the most superior material to absorb and dissipate movement.

Nectar is so confident in their mattress they offer a 365-night trial and a forever warranty (this is unheard of in the UK). We rate the Nectar mattress so highly it also made it into our Best Mattress UK list.

2. Brook and Wilde Lux Mattress

What makes the Brook and Wilde mattress a great pick is the comfort choices they offer. Brook and Wilde offer their premium mattress in soft, medium and firm, this at least gives couples an option compared to the other “one size fits all” brands.

This mattress has two spring layers; the first a 2000 mini pocket spring layer and further down the mattress, full-size pocket springs for extra push back and support. The Brook and Wilde Lux mattress is 28cm thick which is slightly thicker than average. Which as previously mentioned is great for cushioning.

Finally, to conclude, the Brook + Wilde mattress comes with a 100-night home trial and a 10-year guarantee. Additionally, the mattress is delivered with free premium delivery.

3. Emma Original Mattress

The Emma Original mattress is a great consideration for those couples looking for a balanced feeling mattress. It is rated at about a 6.5/10 in terms of firmness feel so it should appeal to the majority of couples in the UK.

The Emma mattress is a 3-layered memory foam mattress. It has its own proprietory "Airgocell" foam layer which is used as a top cooling foam layer. This allows for the mattress to breath better and not maintain as much heat as memory foam mattresses are known for, which may be an important factor for those of you who sleep hot.

Included with the Original mattress from Emma is a 100-night trial for you to try it out in the comfort of your home, as well as a 10-year warranty to ensure the mattress stands the test of time.

4. Tweak Duo Mattress

Included in our Best Mattress for Couples is the fully customisable Tweak Duo mattress. Each partner can choose his or her comfort level, you can choose between soft, medium and firm. This way no one has to compromise. Tweak Slumber offers 1 free layer change if you have tried out the mattress and find it's not perfect for you, this shows the lengths they are willing to go to get you your best nights' sleep.

The seamless mattress split also reduces movement from one side of the mattress to the other. The mattress also includes 1,000 encapsulated full-sized springs to ensure enough pushback and edge support. Springs are also known to allow better airflow, so if you are hot sleepers this may be a great consideration.

The Tweak Duo mattress comes with a 100-night trial and a 10-year warranty. Deliveries and returns are at zero cost to you.

Mattress Considerations for Couples

How do you choose the perfect mattress? Well, it is important to know what you will want to expect from your purchase and to find the optimal solution for both of your sleeping needs. Below we outline the main considerations before buying a mattress as a couple.


First things first, you both need to fit and depending on your preferences you may want to opt for a large or small mattress. The most recommended mattress size for couples is the king size, it offers enough personal space for each of you yet is also intimate enough.

We put together a list of all the sizes currently available in the UK. Take a look to see what size best suits you and your partner (we suggest at least a Double size mattress). Some brands offer more sizes than others but they all offer at least the standard double, king and super king sizes.

Small single size mattress 75x200x25 cm
Single size mattress 90x190x25 cm
Small double size mattress 120x190x25 cm
Double size mattress 135x190x25 cm
King size mattress 150x200x25 cm
Super king size mattress 180x200x25 cm
EU small single size mattress 80x200x25 cm
EU single size mattress 90x200x25 cm
EU double size mattress 140x190x25 cm
EU double L size mattress 140x200x25 cm
EU queen size mattress 160x200x25 cm
Emperor 200x200x25 cm

Motion Isolation

This is a very common term when used to describe a mattress but what exactly does it mean? It means how much energy/movement is absorbed by the mattress when one moves. No one wants to roll and awake their partner or be woken up from the other's movements. Having great motion isolation is a huge benefit for most couples, it can be the difference between a perfect nights sleep and not sleeping at all.

motion isolation and transference

Memory foam and foam combination mattresses are best when combating movement along the mattress, they absorb and dissipate movement very well. On the flip side, they may lack the springy feel Hybrid mattresses have to offer.

Bounce/ Sex

When purchasing a mattress, sex could be an important aspect that shouldn’t be overlooked, especially for couples. Factors that can be used to asses if a mattress is great for sex include:

  • Durability – The warranty offered is a great way to see the manufacturers confidence in the long run.
  • Support – High-density foam mattresses and hybrid mattresses offer great push back and support.
  • Edge support – Typically spring mattresses or mattresses with reinforced sides don’t give in to edge collapse.
  • Thickness/cushioning – We would recommend a mattress at least 25cm in thickness.

Hybrid and spring mattresses provide the most amount of bounce for sexual activity but lack the motion isolation previously mentioned, this give and take situation is something that you and your partner will have to decide on.

See our best mattresses for sex for more ideas.

Firmness & Feel

Perhaps the most important aspect when deciding on a new mattress for couples. The firmness is rated on a scale from 1 to 10, 1 being the softest and 10 being the firmest. The online mattress brands currently out there in the UK generally offer firmness feels from 4 through to 8.

This may be the biggest issue if you and your partner have different preferences. However, modular mattresses offer customisability that lets you choose the firmness of each side. This not only solves the conflicting preferences but also reduces motion transference with its split foam design.
