Warm it up. Memory foam mattresses are temperature-sensitive. This makes them able to react to body heat and mould to your body shape accordingly. They become softer in the heat and firmer in the cold. So, if you bought a mattress during winter season and can't break into it, try turning the heat up.
How do you make a mattress topper fluffy again?
What do you do if your memory foam mattress is too firm?
If you have a memory foam mattress, it can stiffen in colder temperatures. Try raising the thermostat by a few degrees to soften the memory foam. Be careful raising the temperature too much because if you're too hot while you sleep, you might not sleep as well.
Does cold ruin memory foam?
Freezing a non-gel-infused memory foam can certainly ruin the product as cold temperature increases the viscosity of the foam, causing it to stiffen and become too dense for you to lay on.
How long does it take for memory foam to soften?
Most memory foam mattresses will soften sufficiently and reach peak comfort and body-conforming levels within 2-4 weeks. However, some fast-compressing options will achieve this level of softness in under a week, while others still will take even longer than a month.
Does memory foam get hard when its cold?
At very cool temperatures, memory foam can actually feel hard initially, until the material is able to warm.
Why is there a lump in my mattress?
Lumps are caused by the reverse of sagging—your body is pushing some of the material up as it pushes other parts down. Check your mattress for any sags or lumps—anything more than 2 inches deep is a sign that it's time to replace your mattress.
