Need suggestions and help with DIY

Hello,
I need some suggestions with the diy mattress build.
Here’s some information.
We’re in SoFl.
I am 6-2 230lbs, side with 1/4 stomach sleeper.
My SO is 5-5 140lbs side sleeper and rarely back sleeper.
The bed is platform with slats, Ikea Nordli King

We had Beautyrest Recharge World Class Phillipsburg II Extra Firm for 6 years.
We both liked the mattress but we had to dump it recently.
What we did not like about the mattress was:

  • over time, it developed indents from our bodies; rotating did not help much
  • it was kind of warmish

We also had experience with the following mattresses recently.

Sealy Bed in the Box, 8in Firm

  • my SO likes it
  • I think it is too hard to sleep on the side, my shoulders hurt after 20 minutes

Sealy Bed in the Box, 12in Medium Hybrid, it was free.

  • we both do not like it because it is too soft
  • we feel like we roll to the center
  • it is very hot
  • there’s barely any support
  • we feel when either of us gets up/lies down.

With the above information in mind, what would you suggest?
I was considering the following:

  • 1in firm hd foam
  • 8in combizone coils
  • either 3in firm talalay or
  • 2in firm dunlop and 2in firm talalay or 2in medium talalay.
    Thank you in advance for all suggestions.

Hi nick31.

Welcome to our Mattress Forum. :slight_smile:

Indents from bodies mean premature breakdown of materials (usually). Of course, it can also occur with the natural lifespan of a mattress, but 6 years is not especially long. If you haven’t already, I’d suggest having a look at our Durability Guidelines.

Sleeping hot can be to a number of factor. Phoenix has a super detailed post here about the various things at play in mattress microclimates that you may find interesting.

Without knowing the exact specifications of the other mattresses, it’s hard to make a comparison. Ultimately, even changing 1 small thing (from the encasement to the foam) can change the feel. So, instead of trying to approximate the feel of other mattresses, we recommend just aiming towards what feels best and most supportive for you.

At first glance, your proposed build looks great. You both prefer firm. Dunlop tends to “press back” a little more than Talalay (which is lighter and springier). I’d suggest the 4" broken up into 2" slabs for a little extra cushion in the support/transition layer, but also for easier layer swapping, should needs arise.
