4ft Small Double Mattress

4ft Small Double Mattresses in Ireland - Over 365 Options with Free Delivery

The 4ft small double mattress (120 x 190cm) sits between a single and a standard double, making it the practical choice for rooms that are too small for a 4ft6 but where a single feels too narrow. At Beds.ie, we stock over 365 small double mattresses with free delivery across Ireland and Northern Ireland — a size that is far more popular than many people realise.

Small doubles are ideal for teenagers who have outgrown a single bed, single adults who want extra sleeping width without a full double, guest rooms where space is limited, and box rooms in newer Irish homes where a 4ft6 simply will not fit. The 120cm width gives a single sleeper plenty of room to spread out, and can accommodate two people for occasional use — though for a couple sleeping together every night, a 4ft6 or 5ft is more comfortable long-term.

Same Quality, Smaller Footprint

Our 4ft small double range includes exactly the same mattress types as our larger sizes — pocket sprung, memory foam, open coil, hybrid, and orthopaedic. You are not settling for less quality by choosing a smaller size. The same brands, the same constructions, and the same firmness options are all available at 4ft. Spring counts are proportionally adjusted for the narrower width, so support quality is consistent.

Popular for Box Rooms and Spare Rooms

Irish box rooms are typically 2.1 to 2.5 metres wide, which makes a 4ft small double (120cm) a perfect fit with room for a bedside table on one side. A standard 4ft6 double (135cm) in the same room would leave almost no gap beside the bed. This is the size that makes the difference between a bedroom that feels cramped and one that feels just right.

Mattress Depth and Firmness

Small double mattresses are available in the full range of depths from 18cm to over 30cm, and in firmness levels from soft to extra firm. The same principles apply as with any mattress — side sleepers suit medium, back sleepers suit medium-firm, and front sleepers need firm.
