HD Medicoil Low Profile 5″ Foundation Full

Manufacturer Therapedic

Thank you for your interest in the low profile foundation that can help you acheive a more normal overal bed height. The HD Medicoil Low Profile Foundation could quite possibly be the best built lowered foundation on the market today and it is built to withstand double the weight of any other 4 or 5 inch foundation available. It is constructed by the local Amish community for the Rock Island manufacturing facility. This extended life foundation is assembled with over 3 x the amount of wood beams on the foundations’ top surface. Features include on a queen and king size over 20 wood beam slats for superior strength that runs side to side. While many of our competitors boxsprings only use one center beam running head to toe in a queen size, our Therapedic HD Foundation utilizes two. A second center rail called an I Beam is added for additional reinforcement and strength. The I beam uses the same principle for weight support as the I beam used in constructing a house. They simply do it on a smaller scale. For increased edge support 8 super strong wood edge supports are added to each side of the foundation. Our highest quality wood design surpasses any other conventional wood-build foundation. Superior stabilization and Extra durability.
