How to Pick Memory Foam Mattress Topper Thickness
Confirm Mattress Size and Type
A new memory foam mattress topper should fit the dimensions of your existing mattress perfectly to ensure it functions as intended. Determine the exact size of your mattress before you begin shopping for a topper, and take the mattress type into consideration to help select the right thickness. Mattresses with a pillow top or a quilted top may not require a topper with the same thickness as those with standard tops due to the extra cushioning afforded by these designs. Also, mattresses with specialized tops may have special requirements for rotation.
Determine the Condition of Your Mattress
Take into account your mattress condition when deciding on mattress topper thickness. It’s important to inspect your bare mattress top for obvious signs of wear. Look for areas worn smooth by constant turning or indentations from poor weight distribution. If your mattress is particularly firm or worn, then a thickness of 3 to 4 inches should provide an appropriate level of comfort. These toppers provide greater levels of cushioning and support along with enhanced protection for the underlying mattresses. Mattresses with little signs of wear may work best with a 2-inch topper or less, especially if you prefer a firmer mattress for a good night’s sleep. This also works with mattresses that already have decent padding or a built-in pillow top.
Consider Memory Foam Density
A final consideration that can be as important as your topper’s thickness is the memory foam density. When it comes to memory foam, denser material offers greater support for sleepers while less dense memory foam makes for a plusher sleep surface. Those who toss and turn frequently at night can benefit from a denser foam. For mattress density to make a noticeable difference, a minimum thickness of 2 inches is recommended for most sleepers. The lower the density, the easier it is to keep cool with a memory foam topper.
