If you are shopping for a single mattress, you are actually shopping for what’s commonly referred to as a twin mattress. The dimensions of a single, or twin, mattress are approximately 38” x 74.5”. Dimensions can vary by ½” based on the single mattress model.
Two single mattresses placed side-by-side equal the dimensions of one standard king size mattress, and can also be an ideal solution for couples using a king size bed that can’t agree on mattress comfort. There are even more advanced options for single mattresses, including couples choosing two single iComfort® gel memory foam mattresses based on their individual model and comfort preference, and pairing each mattress with its own adjustable foundation, while still sleeping side by side.
