Latex Mattress Factory vs HyPURGel

At least you can buy both Dunlop and Talalay latex from Arizona Premium Mattresses, Latex Mattress Factory/DIYMattress.com.

If you want to purchase a mattress from LMF, just give them a call, and they can help you select the layers. They have sold tons of latex mattresses, so their guidance is more valuable than what you can get on this forum.

Once you have the density, you can reach out to Arizona Premium Mattresses, Latex Mattress Factory, SleepEZ, DIYMattress.com, they can sell you all the layers, including the mattress case.

Just buy a modular latex hybrid from Arizona premium mattresses or latex mattress factory or sleepEZ or diymattress.com

Ideally I'd like to keep the Serene > Hypurgel comfort layer, though I can live without. I really like this combo. I feel like the hypurgel airiness saves the serene from getting too hot. They aren't too temperature responsive and they feel oddly supportive and soft.

HypurGel adds a buoyant, cooler feel but won’t match memory foam’s deep cradle-great as a thin top layer if you hate the stuck feel.

It's good stuff. I use it in my DIY. The cooling effect is subtle at best. I think it's very supportive and conforming, but it doesn't make up for having the wrong mattress core.

There are plenty of temperature-neutral polyfoams like Serene and HyPURgel that don't suffer from the heat sink issue traditional memory foam has.

there's also HyPURgel, that should be more durable than conventional polyfoam
