Split King v King/ how firm is firm?

Hello! I think I’m almost ready to pull the trigger and order my latex mattress. When I plug in our details at the Sleep EZ site, though, it gives me suggestions that don’t feel quite right to me, but that may be because I can’t get out and actually TRY latex, so I’m just guessing.

Here are our details:
Husband is 6’1" 280 lbs, back sleeper, chronic insomniac with a bi-pap and a variety of prescription sleep meds Does not complain of any pain upon waking
I am 5’6", 170 lbs, mostly back sleeper, but I do like to roll onto my side. My time on my side is short b/c it hurts. Don’t know whether this is my current mattress or my aging body or both. I wake with pain in the muscles of my mid-back and around my hips. I sleep with a low pillow under my knees to reduce my lumbar curve.
we are 54 and 53.

Mattress preferences: we have had an original Tempurpedic for 24 years, avoiding replacing it b/c current memory foam all feels “soupy.” What we like about the old TP is that it is firm to the touch, like wet sand, that we are very much sleeping “on” rather than “in” the mattress. I require total motion isolation. I go to bed first and like that I do not feel my husband get into bed.

I’m anxious about DIY bc I don’t want to mess it up, but also worry that pre-made mattresses are just going to be too squishy for my taste. So I’d love a little guidance on getting it right. Thanks!

The Sleep EZ website calculator says my stats indicate Firm, Medium, Soft and Firm, Medium, Medium for my husband, but I don’t think that’s what we would actually like. I’d love some help making the decision so I can get a new mattress at last!

Side question: I live in Frederick, MD and googled “Latex mattresses near me” and got a hit for “organic mattresses” and an Ashburn, VA address. They list Sleep EZ mattresses, but clicking “shop” just sent me to your website. Are they a local distributor or are they just someone who has set up a site to get click-through cash?
Thank you!

Hi SixGables and thank you so much for reaching out! Please keep in mind that our initial recommendations have a 90% success rate (we only have a 10% layer exchange rate) so there’s a 90% chance that the above recommendation works perfectly for the two of you. Aside from that, there is a company called Savvy Rest that sells mattresses very similar to ours, and they have a showroom in Baltimore and one in DC, and I’ve included their information just below. I’m not sure what website you saw us mentioned on, but we just have the one showroom in Tempe, Arizona and we don’t have any other stores selling our mattresses.
