That said, we think it suits back and stomach sleepers the most.
Lighter weight to average weight side sleepers will need to give themselves time to settle into this one.
It isn’t so much a major departure from the previous model as it is a facelift.

It’s rated medium-firm by the brand, although we found it skews slightly firmer.

Those faults aside, we think the Casper One is a good value for the cost.
That’s our Casper One Mattress review in a nutshell.
Fortunately, regularCasper mattress sales cut 20% to 30% off this already-affordable all-foam bed.
The Casper One comes with free shipping and returns, a 100-night risk-free trial, and a 10-year warranty.
Those are the industry averages and what you’d expect from a mid-rangemattress in a box.
However, for the best monthlymattress sales, we recommend holding out for Memorial Day in May.
On top is an open-cell Breathe Flex Foam the company says promotes airflow and cooling.
That’s followed by a layer of Align Memory Foam for pressure relief.
The foundation of the mattress, known as the Casper Core, is meant to prevent sagging.
The Casper One doesn’t contain fiberglass but instead uses rayon-based fibers to act as a flame barrier.
However, she was pleasantly surprised at the slight give of this mattress.
Coming from an exceptionally plush mattress, the firmness of the Casper One took some getting used to.
We objectively tested the pressure relief of the Casper One by placing a 56lb weight on the surface.
The dumbbell sank about 4 inches.
While they did sink slightly, they still felt aligned throughout the night.
This becomes problematic due to the second layer of plastic protecting the interior of the mattress.
Upon removing the first layer of plastic, the mattress begins to immediately inflate.
It felt like a race against time to remove the second layer of plastic before the mattress fully expanded.
Within a few days, there was no smell at all.
We repeated the tests twice for confirmation but the results were the same each time.
The motion isolation here is simply exceptional.

That was not the case with the Casper One.
The thickness of the cover felt warm beneath the sheets, especially when we had the heat turned on.
If you’re a hot sleeper or dealing with night sweats then we suggest going for a specialistcooling mattress.

Side sleepers may not find it comfortable, at least at first, but our tester eventually settled in.
Hot sleepers won’t find the cooling relief they need here, either.
