Whether you enjoy reading or watching television in bed or need a little help finding just the right position to sleep in, adjustable bases provide a degree of comfort and versatility that regular foundations do not offer. Available in twin, full, queen or king sizes, Ortho adjustables allow the user to elevate or lower their head and feet to any desired position. All Ortho Mattresses can be made to be adjustable-friendly so our customers have a wide variety of comfort preferences to choose from.
