Make your bed every morning and smooth the topper with your hands for a flat, even surface come nightfall. A memory foam mattress topper adds a plush layer to your bed that conforms around your body to create a cocoon-like effect. But cold weather makes it difficult for the foam to release the indentation left by your sleeping form, and if you place the topper over a lumpy or sagging mattress, it imitates the shape of the mattress just as easily as it does your body, resulting in a lumpy, uncomfortable surface. For the best results, address the problem from two angles. Give the memory foam the space it needs to regain its shape and treat the underlying issue causing the uneven surface. Remove the memory foam topper from your bed. Take this opportunity to vacuum your mattress with an upholstery brush attachment, removing dirt and dust mites. Relocate the mattress topper to a warm room and lay it flat on the floor. If you see any noticeable lumps or indentations, massage the area with your hands to warm up the material, smoothing it out.
The material is flammable, so do not use an iron, hair dryer or other appliance to heat the foam. Memory foam responds well to the heat of your hands. Let the topper sit for 24 to 72 hours: The more distorted the surface, the longer it needs to release the lumps and indentations. Memory foam naturally reshapes itself when left alone on a flat surface. The warmer the room is, the faster the process will go. Rotate a single-sided mattress 180 degrees, moving the current head area to the foot board. This prevents uneven wearing in the mattress, and any indentations causing lumpiness will work themselves out over time, provided the mattress itself isn’t damaged. Repeat this process every 4 to 6 months. Flip a double-sided mattress over and rotate it 180 degrees. This moves the flat, smooth surface previously sitting on the box spring or platform to the top and the lumpy side of the mattress to the bottom, while relocating the head of the mattress to the foot. The weight of your body and the flat surface of the box spring or platform will smooth out lumps on the previously slept-on side over time.
Rotate the mattress again in 4 to 6 months, and flip it over every 8 to 12 months. Cut a piece of plywood to the size of your mattress and place this in between the box spring and the mattress. A worn box spring causes sagging and promotes the creation of lumps in the mattress; the plywood acts as a solid, firm barrier, increasing support. Remove the pillow-top portion of the mattress, if possible, and machine-wash it according to the care directions on the tag. Dry the pillow-top on low with two to three tennis balls to flatten out any lumps. Reinstall it on the bed. Adjust the temperature in your bedroom if possible, at least during waking hours. An excessively cold space causes the memory foam to seize, making it difficult for it to return to its normal, flat form during the day. During the day, open curtains, allowing sunlight to naturally warm the space. Temperature preferences are personal, so use your best judgment. If your mattress is in good condition, yet the memory foam still shows your body shape after sitting all day, adjust the temperature by 2 to 4 degrees and gauge the topper's response.
