The Royal-Pedic Pillowtop Mattress features a double heat tempered, Royal-Flex® 704i Innerspring System designed in Switzerland. The innerspring unit contains 85% more coils than is standard. The coils in the mattress are open ended, unknotted, six turn coils providing more flexibility, which means greater sensitivity to body contours, overall body support and relaxation. Royal-Pedic skilled craftsmen hand layer the staple cotton padding on each side of the innerspring unit to ensure a consistent, supportive sleeping surface. Over 50 pounds of pre-compressed staple cotton go into making a king size Royal-Pedic Pillowtop Mattress! No polyurethane foam padding layers are in the mattress so you have lasting support for your body and a healthier sleeping environment. The inner cotton padding is encased in 100% cotton fabric, and inner tufted by hand with European tufting straps to further pre-compress the cotton padding for orthopedic back support. * The pillowtop portions are sewn into each side of the mattress. The Belgian 100% cotton covering is quilted with layers of chemical free, French wool followed by hypo-allergenic comfort fill for an added plush feel, and supported by a layer of top quality natural latex for added cushioning and pressure point relief. T-Spring Side Supports are installed around the perimeter of the spring system to provide edge firmness and support. OPTIONAL: The Royal-Pedic Double Diamond Box Spring construction is the finest, the most comfortable and durable box spring available. Royal-Pedic provides 22% more coils than is standard for extra support and durability, and has 50% more coils located in the center-third of the box spring to support the body better (over 60% of our body weight is located in our torso area). This higher coil count results in more coils that are closer together, providing additional support for the mattress to prevent lumps in the mattress from developing. The thickness of this coil wire is an extra heavy duty 8 3/4″ gauge compared to the standard 9?” – 10″ gauge wire used by others. Royal-Pedic box spring units last for many, many years. The coils are double heat tempered to resist sagging and provide more durability. Double heat tempering is when the coils are baked in an oven, cooled down and then baked in the oven again. Royal-Pedic uses a wire system called the Webster Lock Grid System to keep the coils in place. Steel wire is woven throughout the tops of the coils to secure the coil in place to eliminate the possibility of any lateral movement. The foundation Royal-Pedic uses to mount the coil springs is an extra wide slat version to provide more support for the coil to rest on – the same width of slat that is required for 5 star hotels for the assurance of superior durability. Royal-Pedic box spring contains a layer of staple cotton padding for added support for the underside of the mattress. Brass corner guards are installed on all corners, rather than the plastic ones that break off easily, and heavy duty cotton fabric is used on the underside of the box spring, instead of the thin synthetic sheeting that commonly droops and frays easily. You will only get the best with Royal-Pedic! All Royal-Pedic mattresses are custom made to exactly fit your needs. After placing your order, please allow 1-2 weeks for the mattress to be produced and shipped to you. Price: $ 5852.0 Read More and Buy it here!
