Not even remotely.
Even firm memory foam feels cushy to an extreme. You sink into it with no “push back.” Latex/coil hybrid beds have a firm feel and very springy. You don’t sink into them much and they’re easy to get in and out of. This bed in particular is very firm (but in a fantastically supportive way, I find). However, the latex does an excellent job of preventing motion transfer and does wonders for things like back, neck, and hip pain. They’re equal in terms of supportiveness, but they offer a different kind of support. Memory foam conforms to your body but doesn’t offer resistance. Latex/coil doesn’t conforms less but offers resistance. It’s a personal preference thing.
