Adding to base layer?

Hi AT,

Congratulations on your new mattress :slight_smile:

As you know the BME is a great quality/value choice and it’s good to hear that it is working well for you in terms of temperature regulation as well.

I’m not so sure that you would “feel” an additional 3" of foam material underneath your mattress (although this would depend to some degree on the body type and sensitivity of the person and on the specifics of the material and the firmness that you were using) or that it would add any additional “support” (if the material provides additional flex under your mattress in some cases it could have a negative effect on the support of the mattress) and I’m also not so sure that I would add anything under or over a mattress based on how it feels when you jump on it vs when you are sleeping on it.

Having said that … if some additional height is important to you then you could add a taller foundation, you could add some risers under your bedframe (see some examples here), you could add some taller legs directly under your foundation (see some examples in post #8 here), or as you mentioned you could also add a foam layer (I would probably choose polyfoam) under your mattress.

If you do decide to add a polyfoam layer I would probably try using the firmest polyfoam you could find (the firmer the better so it has the least possible amount of flex and the least possible effect on the feel and performance of the mattress) and add a cover to it for appearance and put it in between the mattress and the support system (foundation or platform bedframe) under your mattress.

Some of the better online sources for polyfoam I’m aware of are listed in post #4 here.
