Tips for Sleeping on Memory Foam in Cold Temperature

memory foamAs the fall season takes deeper hold on the country and overnight temperatures dip into colder territory, you might notice that your memory foam mattress or mattress topper feels a lot more stiff and rigid than it did in the summer. This is because memory foam is a temperature-sensitive material that responds to its environment in a way that ordinary coil spring or pocket spring mattresses do not. Memory foam mattresses are flexible and pliant when warm, but the opposite when cold.

But just because your memory foam mattress or memory foam mattress topper is behaving as expected in cold temperatures, that doesn’t mean you have to suffer through a breaking in period each night before you sleep. Here are some tips to help get memory foam sleep ready when the weather turns chilly.

Warm up the room

Since memory foam responds to ambient temperatures, one of the best ways to ensure your mattress or topper doesn’t feel too stiff is to warm up your bedroom approximately 30 minutes before you sleep. This will give the material enough time to warm and soften so you can rest comfortably.

Add extra blankets to the bed

If you don’t want to warm up the whole room, you can simply focus on warming up the bed. This is easily achieved by adding extra blankets (wool, fleece, or down work best) over your or topper, which will insulate the material against the cool air temperature. Note: Since memory foam retains body heat as you sleep, do not keep the extra blankets on after you turn in for the night.

Refrain from using hot water bottles or electric blankets/electric heating pads

Tempting as it may be to warm your memory foam mattress as quickly as possible with a hot water bottle or electric blanket/heating pad, we advise you not to do so. Such direct applications of heat can damage the memory foam material and not only compromise its performance but also shorten its overall lifespan.

      Thank you for reaching out to Foam By Mail via our blog.

      Based on your question, you can actually place the heating mattress pad right on top of the memory foam. As memory foam is affected by temperate and the warm pad will always keep the memory foam soft.

      However, if that is not what you are interested in, than you can purchase a standard conventional foam to place on top with the heating mattress pad over that. This will not affect the memory foam on the mattress underneath.
