It’s unyielding, with the bare minimum cushioning.
And that means trying mattresses outside our (quite literal) comfort zone.
After over a week, my opinion has completely changed.
The support is superb and once you’ve gotten past the initial hardness, some cushioning comes through.
What is the Plank Firm mattress?
The Plank Firm is a double-sided mattress: firm on one side, and extra firm on the other.
it’s possible for you to read my first impressions of the bed with myPlank Firm Mattress hands-on review.
Before I dive into my experience with the Plank Firm, let’s talk a bit about firmness rating.
We measuremattress firmnesson a scale from 1 (incredibly soft) to 10 (rock-hard).
The build is incredibly simple.
At the core is a 6" layer of high-density support foam.
This is primarily responsible for the feel of the mattress and provides the bulk of the support.
On the extra firm side, the only thing between you and the support foam is the cover.
The basic quilted design leaves the surface almost entirely flat.
Like all thebest mattresses in a box, the Plank Firm comes rolled and vacuum-packed.
My experience sleeping on the Plank Firm
The Plank Firm is a double-sided mattress.
So for testing, I decided to jump right in with the extra firm side.
I’ve now been sleeping on the extra firm side for more than two weeks.
As astomach sleeper, I prefer sturdy support at my hips.
There’s none of that with the Plank Firm.
Thebest mattresses for stomach sleeperstend to have some padding, but the Plank is flat and firm.
The all-foam build of the Plank Firm can be a little misleading.
Thebest memory foam mattressestypically have cushioning and contouring, but the Plank Firm has an almost deadened effect.
This makes it an easy mattress to move around on.
The freedom to toss and turn immediately appealed to me.
The Plank Firm could rival thebest mattresses for back painfor how it continually supports my lumbar region.
That support can be felt in every corner of the bed.
Theedge supportis strong, and even sleeping right up against the side there’s no sink.
At this point, the firmness was still requiring some adjustment.
As someone used to a plush hybrid, it was a little disorientating.
Night 8+: Support still shines, some cushioning?
Having spent more than a week sleeping on the Plank Firm, I’ve gradually grown into the firmness.
And to my surprise, I’ve started to notice some cushioning.
(Yes, really!)
That touch of comfort helps me really appreciate the support of the Plank Firm especially at the hips.
The more pressing issue with the Plank Firm and pressing is the operative word is for side sleepers.
Without soft or responsive upper layers there’s almost no relief where your shoulder presses against the mattress.
The Plank Firm is for people who know exactly what they want from their bed.
