King size mattress. Stearns and Foster. Smoke free home. ALWAYS had a mattress cover on (just took off for photo back on now). 4-5 years old.
Also adjustable base for king mattress (so no box spring, because it sits on the adjustable base that has height on it). 2 remote controls. Works and can elevate head or feet or both. Older model. Unsure of how old. Also remotes can be funny - like sometimes doesnt work but then if I take out batteries and put them back in - it then works fine.
