Best overall extra-firm mattress: Plank Firm Luxe. It’s the safest first pick if you want a truly firm, supportive feel because it is flippable with two firmness levels, so you can choose between firm and extra-firm at home.

What could change this answer

Firmness is subjective.
Before buying, check the current trial period, return fees, warranty terms, mattress height, bed-frame compatibility, and whether the brand’s current model has changed.
