A standard Twin mattress measures approximately 38 × 75 inches. These are nominal dimensions; check the measurements and any stated manufacturing tolerance on the selected product page before matching it to your frame.

Twin and Single commonly refer to the same standard 38 × 75 inch mattress size in Canada. Twin XL is a different, longer size. Check the selected product and frame dimensions rather than relying on the name alone.

Only if its size and mattress height meet the bed manufacturer’s requirements. Bunk-bed guardrail clearance and maximum mattress thickness are especially important. Check the frame instructions and the selected mattress’s dimensions before ordering.

Explore the currently available foam, pocket-coil hybrid, innerspring and latex models using the mattress-type filters. Classifications vary by model. Read the complete product construction before deciding which materials and support system you prefer.

Start with the feel you prefer, then compare each model’s confirmed firmness. Our mattress chooser matches size, budget, preferred firmness and mattress type. Models without a confirmed classification remain visible when no firmness filter is selected.

Thickness describes mattress height; firmness describes feel. A thicker mattress is not automatically firmer. The confirmed model firmness applies across its available thicknesses. Compare the stated feel and available heights separately.

The cards compare variants in Twin size. A starting price is the lowest-priced available matching option, or a matching sold-out option if none is available. A thickness or price filter can change the selected variant. Review the final variant, availability and price on the product page. Prices are in Canadian dollars before taxes.

Measure the inside of the frame and compare it with the selected mattress’s dimensions. Check the frame’s support requirements and maximum mattress height. Review your foundation and fitted sheets as well as the mattress itself. Ask our team if you need help checking a particular setup.
