The Verdict

A Firmer Medium That Sleeps Surprisingly Cool

We started our Muse review with the brand's sleep-personality quiz, a short set of questions that matched us to a Muse Medium queen mattress paired with a Low Loft Support pillow.

The Medium runs a 6 out of 10 on firmness, a touch harder than average compared to other beds we've tried. A gel-infused memory foam top layer lets the sleeper sink in a little and hug the body, backed by 2 inches of memory foam and an 8-inch high-density foundation that supports both back and side sleepers.

Sinkage lands around 2 inches, so the Muse never feels like it swallows the sleeper, and horizontal motion transfer is minimal, letting a restless partner move without disturbing the other side of the bed.

Muse's cold-wire technology is the standout feature: we don't know exactly how it works, but it genuinely reduces heat buildup, and we haven't found customers complaining about sleeping hot, even in warm climates. Earlier off-gassing complaints have also faded since Muse moved manufacturing from China to the US.

At around $900 for a queen, with a 120-night trial and a $150 discount code, the Muse is a fairly priced, cool-sleeping medium-firm bed for back and side sleepers who don't want the bounce of latex or springs.

Pros

Why We Love It

  • A slightly firmer mattress that is ideal for back sleepers
  • A fair price for a high-quality bed
  • Perfect for hotter climates because it sleeps so cool
  • Very little horizontal motion transfer, so sleepers won't disrupt their partners
  • Made in the USA
Cons

Considerations

  • Full memory foam lacks the responsiveness of latex or spring mattresses
  • Slight amount of off-gassing

Our Hands-On Review

We began by taking the Muse sleep quiz, which matched us to the Medium queen mattress with a Low Loft Support pillow. On the bed itself, the density of the top layer allows around 2 inches of sinkage, positioning sleepers higher in the bed than a plusher mattress would.

The full memory foam construction absorbs energy well, so tossing and turning on one side barely registers on the other, with the tradeoff being less bounce than a latex or spring mattress.

Cold Wire Technology, Explained (Sort Of)

Muse's cold wire cover does an excellent job reducing heat, even though we don't know exactly how the technology works. We found zero customer complaints about overheating, even in the hottest cities.

We Recommend This To Readers Who:

  • Want a medium-firm bed

    At 6 out of 10 on firmness, the Muse runs a bit firmer, working well for a wide range of sleepers.

  • Want a moderate level of sinkage

    Around 1.5 to 2 inches of sinkage keeps the bed feeling soft without ever feeling like sinking in.

  • Want a cool sleeping experience

    The Cold Wire Plus cover combined with gel-infused memory foam delivers a notably cool night's sleep.
