Why EU sizes matter in UK homes#

European mattress sizes are increasingly common in the UK because IKEA, one of the UK's most popular furniture retailers, uses EU dimensions throughout their bed frame range. If you own an IKEA MALM, HEMNES, SONGESAND or any other IKEA bed, you need EU-size mattresses. A standard UK double (135 × 190 cm) will not correctly fit an IKEA double frame (140 × 200 cm).

IKEA mattress alternatives#

You don't have to buy an IKEA mattress for an IKEA frame, but you do need EU dimensions. UK brands offering EU sizes include Silentnight, Sealy, and some online brands (Emma offers EU single; EU double availability varies by brand). Always confirm EU dimensions before purchasing from a non-IKEA brand.

Measuring your bed frame#

Measure the internal sleeping surface of your bed frame (the area the mattress sits in), not the outer frame dimensions. A mattress should fit snugly with no more than 2–3 cm gap on any side, wider gaps create an uneven sleep surface and allow the mattress to shift.

Can you use a UK mattress on an EU frame?#

A UK double (135 cm) on an EU double frame (140 cm) would leave a 5 cm gap on one side, noticeable and potentially hazardous if you roll into the gap. A UK single (190 cm long) on an EU single frame (200 cm) would leave a 10 cm gap at the foot. Neither is recommended. Always match mattress and frame dimensions.
