Refurbinsh : Simmons Beautyrest Black Abriana (King)

I have a SIMMONS BEAUTYREST BLACK ABRIANA “Extra Firm” MATTRESSES (king). It’s sagging a lot, causing sleepless nights. Per viewing your YouTube channel: I need a mattress cover and new foam/layers (extra firm) to DYI rebuild this mattress. What is the next step? Many thanks, Matt / Lakewood Co :

The videos walk you through how to remove the failed parts. Then measure what is left that is good and order the replacement latex and also correct height cover. Call me direct if you need assistance in choosing what latex to get. 888-773-73216
