Make a Mattress Sling
Here's an easier way to carry a mattress: Make a simple rope sling that will give you and your helper a lot more control. Thread the rope through the mattress handles. Slip a 5-in. piece of 1-in. PVC pipe over the rope ends and then loop and tie each end to create a comfortable sling grip. Flip the mattress over so the sling is on the bottom and you're on your way.
Cut and Fold a Box Spring
Is your box spring too big to fit in your stairway or around a tight corner? You could buy a “split” box spring designed specifically for this (and pay several hundred bucks) or cut your existing box spring and fold it so it fits. There's actually a simple, ingenious way to cut and fold your box spring without wrecking it.
Remove the fabric covering (the most tedious part of this whole process is removing the staples) and place the box spring face down. Pull back the mattress cover along each side and cut through the frame just to the left or right of the middle crosspiece (don't cut through the crosspiece itself). Do this on both sides and in the center. You can now fold the box spring like a book as shown and move it. Secure it with a strap to prevent it from springing open.
To put it back together, screw a 1x2 along the center crosspiece cuts and against the inside of the outer frame to reinforce them. Then staple the fabric covering back in place.
Plan Where It Lands
If you're moving to a new house, decide beforehand which furniture will go where. Before you move, sketch a floor plan with the correct measurements of each room, measure your furniture and create your layout. Then, as you move things in, you (or your helpers, if you're not there) can place your furniture in the correct spot and not have to touch it again. To make it easy on the movers, tape a copy of the plan to the wall of each room so people can tell at a glance where things go.
