How to choose the best mattress for a couple?

Published by Leafsleep on 7th Aug 2025

In this article, we explain everything you need to consider before choosing between the various types of mattresses for couples, from the level of firmness to the ideal size.

When two people share the same bed, it is essential that the mattress offers comfort, support and independence of movement.

 

What is a double mattress?

A double mattress is generally one that has a minimum width of 140 cm, making it ideal for comfortably accommodating two people.

In Portugal, the standard measurement for a double mattress is 190x140 cm. However, there are larger options such as Queen Size (195x150 cm) and King Size (200x160 cm), which offer more space for comfortable sleeping and independence of movement.

Why invest in a good double mattress?

Sharing a bed means adapting your rest to the needs of both people. Differences in weight, sleeping position or even thermal sensitivity are common, and a poor quality mattress can harm the sleep of both.

A good mattress for a double bed helps prevent back pain, sleep interruptions and discomfort throughout the night. What's more, a mattress that's right for a couple will make the bed last longer, improve the quality of sleep and contribute to the couple's physical and emotional health.

What to consider when choosing a double mattress?

Ideal size for the space and for both of you

The double mattress should be wide enough for both of you to move without discomfort. The most common measurements are:

  • 190x140 cm - ideal for rooms with limited space;
  • 195x150 cm or 200x160 cm - provide greater comfort for those who move around a lot or share the bed with children or pets;

 

Type of mattress: foam or springs?

There are several types of double mattresses on the market, but the most popular are:

  • Foam mattress: incorporated with viscoelastic, it adapts to the body, relieves pressure and is ideal for those looking for a more enveloping mattress;
  • Box spring mattress: offers individualized support, reduced transmission of movement and greater breathability. Ideal for those who prefer a double bed with a mattress with good air circulation and balanced firmness.

 

Reducing movement
To avoid waking up to your partner's movements, opt for mattresses with bed independence, which have a high capacity to isolate and absorb movement, so that if your partner moves, you feel it as little as possible.

 

Balanced firmness
Firmness should provide the necessary support without compromising comfort. Medium or medium-high firmness mattresses are generally preferred by couples, as they adapt well to different body profiles and sleeping positions.

 

Thermoregulation

If one member of the couple tends to feel hotter, it's essential to choose a mattress that promotes ventilation and regulates the temperature. Breathable fabrics such as TENCEL™ Lyoncel and foams with viscoelastic gel are great allies.
