@Maverick good points. I know Iām purchasing the mattresss cover from Arizona (I own their cotton cover for another bed and the quality and price is great). I just realized I own the SOL topper cover for our guest bed. Great quality but loose fit.
Anyways, I am communicating with Ken and SleepEZ regarding their covers and will purchase the one that fits my requirements best. Which are tight fit and thin (to get closest to the latex).
Truthfully, Iām still debating one cover vs separate covers for core/topper. Iām leaning towards the latter for all the points you made. Trying to not overthink it as I can also change it in the future but it would be an added cost.
