How long does it take for a new memory foam bed to finish softening up?

Hi Chirurgeon,

The initial break in period will vary depending on the type of foam and on the person sleeping on the mattress but it would typically be 90 days or less and usually in the range or 30 days or less. Higher density foam will take longer than lower density foam.

If you are getting the pressure relief you need then softer means less support not more. If a comfort layer is too soft and thick then the pelvic area can sink down too far and put your spine out of alignment. If you are getting the pressure relief you need on your side I would say you are doing well and you wouldn’t want it too much softer.

With memory foam there are also other factors that can affect the softness/firmness of the mattress and post #2 here may also be helpful.
