Just wanted to update you all. Thanks to this forum’s help, I went with a Sleep EZ 7’’ Latex about a year ago.
I absolutely love it. I went with dunlop for the bottom layer (firm) and talalay for the top (medium firmness). It’s supportive, yet not too firm. There has been 0 sagging at all. I have a bed frame with wooden slats and a coconut bed rug above the slats (to protect the mattress and improve its life).
But yea this is just a thanks to all those that helped and have contributed to the forum. I appreciate it and decided to give some feedback, hopefully to help someone else.
