How can I use my existing bed springs with the OP Loftbed?
Instead of using the plywood mattress platform, you will use your existing springs. Build two more center mattress supports and install them near the head and foot of the bed. This will give you three supports for the existing springs. Be sure to measure your springs first to make sure that they will fit inside the mattress supports. For twin, the springs must measure less than 74″x37″. For twin extra long, the springs must measure less than 79″x37″.
