Perfect!

I was looking for more support something not too hard and not too soft and I settled for the plush and it’s perfect!

Firm and comfortable

The mattress is very firm, which I at first was unhappy about. However now, after several months, I am very glad I chose it.

This mattress is firm and supportive exact comfort for me with a touch of softness like a pillow top. I just love it.
