Yes, some companies—including Brooklyn Bedding and Naturepedic—offer mattresses with different firmnesses on each side of the bed. These mattresses are called split queen or split king beds and have two mattresses within one cover. However, custom firmness mattresses can be expensive, and not every brand offers this option.
For a more affordable and versatile strategy, consider pushing two twin XL mattresses together. Pushed together, two twin XL beds are the same size as a standard king mattress. Using this strategy, you and your partner can each choose your preferred mattress—even if that’s a different brand and different firmness. But if you opt for different brands or models, be sure to check that the heights and dimensions are the same.
