Hello TMU team, I am looking for a KIng Hybrid Mattress with Split firmness. We are not interested in two Twin XL’s; we are looking for one mattress. We have tried the SleepEZ 360 hybrid but found that one of us does not like Latex, too much push back and not enough conformance or hug. The SLeeper 1 who is not a fan of Latex, is 6 ft 215 BMI of 30 has shoulder pain issues and is a side sleeper, and Sleeper 2 is 5.4 BMI of 27 stomach and side sleeper who had lower back pain. So we switched to a hybrid mattress that uses 8-inch coils and 2 inches each of med frim MF and Energex. Sleeper one find it is be supportive enough provides OK pressure relief but would like something with a plusher feel (Like the ASH) We liked the feel of the Nest Sparrow (she liked it with a Med latex insert from the OWL) and Owl but have concerns about the springs and Sleeper 2 wants something Frim. (Allswell basic 8 inch coild with 1-inch ploy form could be frimmer) the only other split frim option I can find is the Brooklyn Beddding custom. Are there other mattresses I should be looking at? I am open to DIY if there is a Hybrid open. Any thouths or suggestions?
