Buying Guide
Size and profile
Measure your room and bed frame before buying — a mattress that fits easily through doorways and up staircases saves stress in a small flat. Consider lower-profile mattresses (around 18–22cm) if you have limited headroom or a loft-style bed.
Type and support
Choose the mattress construction that suits your needs: memory foam for pressure relief, pocket-spring or hybrid for bounce and edge support. In compact spaces, a mattress that provides zoned support helps maintain comfort without needing extra bulky toppers.
Portability and setup
Mattresses-in-a-box are ideal for small flats — they’re rolled, easier to carry and can be unboxed in tight corridors. Check weight, packed dimensions and whether the brand offers a white-glove delivery if you can’t manage heavy lifting.
Firmness and sleeping position
Match firmness to how you sleep: side sleepers generally favour medium to medium-soft for pressure relief, while back and front sleepers usually prefer medium-firm. In a small apartment you may prefer a single versatile firmness (medium) to suit visitors and limited space for multiple mattresses.
Breathability, odour and durability
Small rooms can trap heat and odours, so pick breathable covers and cooling foams or springs to reduce night sweats and minimise initial ‘new mattress’ smell. Also look for long warranties and durable materials to avoid replacing the mattress frequently in a space-constrained home.
