A very common problem that most couples face is the disparities in their sleep preferences. The best solution to this problem is to purchase a sleep number bed which has become very popular today. Most couples are robbed of sound sleep due to the constant tossing and turning of their spouse who is unable to adjust to the bed. This is where these beds come in most useful as each person's side can be adjusted according to their convenience. Each side of the bed can be made as hard or as soft as required and even the slope can be altered to your comfort level.
