The only Brooklyn Bedding that is double sided these days is the Plank and Plank Luxe. I own the plank luxe for 2 years now. Great mattress, super comfortable for me as I like a firm mattress, 6’ 220 (250+ when I bought it). My wife is 5’4 135 and loves the firmer side of the mattress just as much as I do. We are both 80% side sleepers, but coincidentally we both start on our back, then roll to the side. Occasionally, I will end up on my stomach in the morning whereas my wife is still on her side.
At over 200lbs, I recommend rotating any mattress you choose and be certain you have a frame that supports your mattress.
Sorry that the APM did not work out for you as it is an excellent mattress.
If you like a traditional non latex double sided BiB mattress you may want to consider the @DLX classic hybrid. Folks as large as 300lbs have written on Reddit they have slept comfortable on this mattress.
