This was sold on Wayfair as Zinus 10" medium mattress during Black Friday. It showed up when searching for memory foam mattresses. After it shipped it started showing as Zinus 10" Innerspring mattress. Its also complete garbage. Terrible for your back. After selling it through misrepsentation, Wayfair gave 20 dollars to compensate. Do not buy it unless you are very young with a solid back. Its not comfortable at all.
