Double Mattresses: What to Know Before You Buy

A double mattress at 135 x 190cm is the standard choice for couples in the UK, and it is a size that needs to be thought about carefully rather than assumed. At 135cm wide, two adults have around 67.5cm each, which is less than a single bed gives one person. For couples where both sleepers move around, that can become noticeable over time. For those who sleep fairly still and prioritise bedroom space over sleeping width, it is a genuinely practical choice.

The most common question with double mattresses is whether to go memory foam, pocket sprung, or hybrid. Pocket sprung is a good default for couples because each spring responds independently, meaning one person's movement is less likely to disturb the other. Memory foam gives a closer contour to the body and better pressure relief but can retain heat, which some people find uncomfortable. Hybrid mattresses offer springs for support and responsiveness with foam layers above for comfort, sitting between the two in most measurable respects.

Firmness affects how well the mattress supports your spine through the night. Side sleepers typically need a softer surface that allows the hip and shoulder to sink slightly, keeping the spine level. Back sleepers need more support through the lumbar region, so a medium-firm surface is usually better. Front sleeping puts the most strain on the lower back and is generally not recommended, though a firm mattress helps reduce the impact.

Double mattresses are also the standard size for most guest rooms in UK homes. A double gives visitors a comfortable night's sleep without the cost or footprint of a king, and most double divan beds and ottoman beds in guest room configurations use this size.

One practical point worth confirming before buying: double mattresses measure 135 x 190cm in the UK, but European double mattresses are often 140 x 200cm. If your bed frame is from a European retailer, check the internal frame dimensions rather than assuming a UK double will fit.

Frequently Asked Questions

A standard UK double mattress measures 135 x 190cm, also referred to as 4ft 6in. This is the most common mattress size for couples in the UK and fits standard UK double bed frames.

A double mattress can comfortably sleep two adults, but each person has around 67.5cm of space, which is less than a single bed provides one person. Couples who move around a lot during the night may prefer the extra width of a king size mattress.

A king size mattress measures 150 x 200cm compared to a double at 135 x 190cm. The king is 15cm wider and 10cm longer, which makes a noticeable difference in sleeping comfort, particularly for taller sleepers or couples who want more space.

Pocket sprung and hybrid mattresses are generally the best choices for couples, as individually wrapped springs minimise motion transfer across the mattress when one person moves. This helps both sleepers get a less disturbed night.

A standard UK double mattress at 135 x 190cm will fit any UK standard double bed frame. If your frame is from a European retailer or is older, check the internal frame dimensions carefully, as European doubles are often slightly wider and longer than UK standard.
