Bunk Mattresses

Bunk Bed Mattresses in Ireland - Nearly 40 Options with Free Delivery

Bunk beds need specific mattresses — thinner and lighter than standard models so the sleeper on the top bunk does not sit dangerously close to the guardrail. At Beds.ie, we stock nearly 40 bunk bed mattresses with free delivery across Ireland and Northern Ireland, designed specifically for the depth and safety requirements of bunk beds, mid sleepers, and high sleepers.

A standard mattress is typically 20 to 30cm deep, but for a bunk bed the mattress should be no more than 15 to 18cm to keep the sleeping surface safely below the guardrail. Our bunk mattresses are engineered to deliver proper support and comfort within that reduced depth — they are not just thinner versions of a regular mattress, but purpose-built models with appropriate spring systems and foam densities for a slimmer profile.

Sizes Available

The most common bunk mattress size is 3ft single (90cm) with 19 options — this fits the vast majority of bunk beds sold in Ireland. We also carry 4ft6 double bunk mattresses with 7 options for the lower bunk of triple sleepers, 4ft small double with 4, 2ft6 small single with 1, and European single (90 x 200cm) for bunks with longer-than-standard sleeping platforms. Our European length mattresses are available in 3ft by 6ft6, which is the size used in many continental and IKEA-compatible bunk frames.

What to Look For

Firmness should be medium to firm for children — growing bodies need consistent support. Check the maximum recommended depth for your specific bunk bed model before ordering, as guardrail heights vary between manufacturers. Weight ratings matter too — most bunk mattresses are rated for lighter sleepers, so if an older teenager or adult will be using the bunk regularly, check the maximum weight specification.

Replacing an Old Bunk Mattress

If the current mattress is showing its age — sagging, lumpy, or stained — a fresh bunk mattress is an affordable upgrade that makes a real difference to sleep quality. Children often do not complain about a worn mattress, but a new one can noticeably improve how well they sleep.
