Plush Single/Twin Size Mattresses
38” wide by 75” long
A single mattress (also called a twin mattress) measures 38” wide by 75” long — the standard choice for one sleeper and the most space-efficient mattress size available.
It’s ideal for children transitioning out of a toddler bed, teenagers, single adults in compact spaces, bunk beds, daybeds, and trundle setups.
Every single mattress at National Mattress ships free across Canada with a 365-night sleep trial, price match guarantee, and 5–25 year manufacturer’s warranty.

How to Choose the Right Single/Twin Mattress
A standard single/twin mattress measures 39" × 75" (99 cm × 190 cm), making it the most versatile size for children’s rooms, guest bedrooms, bunk beds, and daybeds or trundle beds. At National Mattress, over 95% of our twin mattresses are manufactured in Canadian factories, and all feature CertiPUR-US® certified foams tested for harmful chemicals and low VOC emissions.
Start by matching firmness to the sleeper: children and stomach sleepers generally need firm to extra firm support, while side sleepers benefit from medium or plush cushioning for pressure relief at the hips and shoulders. Construction type matters too, euro-top and pillow-top models add comfort layers on top of pocket coil or foam cores, while memory foam and latex mattresses excel at motion isolation and contouring. For bunk or loft beds, follow the frame's mattress-size and thickness limits. Health Canada guidance calls for 12.7 cm (5 in) of guardrail above the mattress on every side; subtract 5 in from rail height above the slats.
