Is memory foam bad for sex?

Current Events

My mom and brother are pitching in together to get me a nice queen bed but it's memory foam.

Very noticeable how less bouncy memory foam is. Worried about sex because one of the best tricks is to use the other person's w weight to your advantage and have the mattress do the work and bounce them back up.

But it's such a nice gift I don't know how to begin telling my brother or mom I don't want it or if we can return it It's still in the box
