Our Verdict
The closest thing to sleeping on a properly supportive floor with just enough cushion. If F.M. Alexander designed a mattress, it might look something like this. Maximum proprioceptive feedback, zero interference.

The Plank Firm is one of the few mattresses designed specifically for people who prefer a firm sleeping surface. It's a flippable mattress with a Firm side and an Extra Firm side, using high-density TitanFlex foam.
Why we recommend this mattress
Most mattresses try to convince you that softer is better. The Plank takes the opposite stance, and from an AT perspective, it's right. A firm surface allows your skeleton to bear weight properly, which means your muscles can stop working overtime. The flippable design means you can practice constructive rest on the Extra Firm side and sleep on the Firm side.
What works
- +Highest feedback score in our reviews — your body gets unambiguous information
- +Flippable design: Firm side for daily use, Extra Firm for constructive rest practice
- +Zero zoning, zero contouring — pure non-interference
- +The surface encourages your muscles to actually release rather than being 'held'
What to watch for
- –May be too firm for side sleepers initially — requires a transition period
- –Foam construction means slightly less responsiveness than latex or coils
