Your futon mattress seems to have a mind of its own. Your cotton or spring mattress tends to slide forward and slouch. Your polyurethane mattress is jumpy and springs out of position. No amount of pushing, pulling, or karate-chopping keeps it in place. This sagging, jumping, and general restlessness is caused by a serious lack of friction. The simple fix is to introduce some GRIP between your mattress and the seat of your futon frame.
Enter the "gripper" (pictured left). The gripper is an essential futon accessory made of non-slip foam. This modern-miracle anchors your mattress into place and keeps it there! (The same kind of material is also commonly used to keep floor rugs in place.)
If needed, cut the gripper to fit within the seat of your futon. It doesn't have to fit perfectly. To install your gripper remove your mattress from the frame, unroll or unfold your gripper across the wooden slats of the seating area. It should rest in place on its own without falling through the little gaps between the wood.
Tip: for a very jumpy mattress, try slipping a second gripper between the back-rest and your mattress.
Place your mattress back on top of the frame, taking care not to disturb the gripper in the process. Voila! Your mattress is now happliy in place for you to enjoy. Now that you know, make sure to tell a friend!
The fastest way to get your own mattress gripper is to call your local futon retailer and ask if they have one in stock for you.
Another local option is to call a nearby carpet store or home improvement center. These stores should know this product as a non-slip pad for floor rugs. Make sure you buy a thin mesh non-slip pad and not the thicker rug or carpet pad. You may need to cut to fit but typically, this cutting job is easily done with a pair of scissors.
If you prefer ordering online, you might try a quick search for "futon mattress gripper" and arrange to have your gripper shipped to you.
