Small double mattresses offer a smart solution when a single mattress feels too tight but a full double takes up too much room. At around 120 cm wide and matching standard length, they provide a comfortable sleep surface for one person and can also accommodate two in a pinch. This size works especially well in smaller bedrooms, guest rooms or shared children’s spaces where floor space still matters. You’ll find a wide choice of support levels, materials and finishes so you can choose what feels right for that room and routine.

Each mattress in this range is built with everyday family life in mind. Strong internal cores, breathable covers and easy-care fabrics make these mattresses both practical and inviting. Whether it’s a growing child transitioning to a bigger bed or a guest space that needs an upgrade, this collection gives you the flexibility to match size, comfort and durability. Take your time comparing the options and pick a mattress that supports peaceful nights now and into the future.
