A standard Double mattress measures approximately 54 × 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.

Double and Full commonly refer to the same standard 54 × 75 inch mattress size. Check the product’s dimensions and your frame before ordering, especially if a frame uses an unusual or older size.

A standard Double is 54 × 75 inches; a Queen is 60 × 80 inches. Queen adds 6 inches of width and 5 inches of length. Compare the space for sleepers and the room needed for doors, furniture and access around the bed.

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 Double 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.
