Does a couple need a particular size mattress?
As a rule, a king or queen size mattress provides the most room and the best comfort. You might want to consider a mattress that minimizes sleep disturbances when either of you move during the night. Some mattresses are constructed to minimize the impact of partners moving. The mattresses in the Simmons Beautyrest product line feature a varying Motion Separation Index, which rates how well the mattress keeps partner movement from disturbing sleep. You should both evaluate a potential mattress purchase. A spacious mattress will help you sleep better and you’ll both be more rested in the morning.
