I"m not sure about that brand either but I got this memory foam mattress.
I like it. I now wear a sleep apnea mask which is uncomfortable unless I sleep on my back so I sleep on my back 99% of the time. I move very little outside of spasms.
The mattress can get warm but the support is great.
Moving on it is hard. I use sateen sheets whenever possible. They make it easier to slide.
