What is the size of a king mattress? 76” x 80” 


Three comfort levels? What are they? Of course! 1. Soft, which is cushiony comfort, without that sinking feeling, that compresses easily to the touch; 2. Medium, which is the best of soft and firm comfort and moderate sink-in; and 3. Firm, which is substantial comfort and minimal sink-in that recovers quickly from contact.   


Which mattress should I pick if I’m a side sleeper? Soft mattresses are generally the best choice for a side sleeper. Something that conforms to your body, while still giving you the support you need. Try a soft memory foam or pillow top mattress—we’ve got several king size options to explore. 


Which mattress should I pick if I’m a stomach sleeper? Firm mattresses are usually the way to go if you’re a stomach sleeper. Choose something with firm foam or dense innerspring for maximum support. Shop our king styles and get comfortable! 


Which mattress should I pick if I’m a back sleeper? A mixture of the two types is typically what a back sleeper needs. Some softness, some firmness, total comfort. Make sure your choice allows your back and spine to feel supported. Browse our king mattresses for back sleepers now.
