Driver Reviews
What Drivers Are Saying
Real drivers. Real miles. Real sleep.
"11 years OTR and this is the first mattress I actually look forward to climbing into. The copper lumbar layer is no gimmick — my lower back thanks me every morning."

"I'm a side sleeper and have never slept well in a truck. The Serenity changed that. The 1,000 coils contour perfectly and I wake up without that stiff hip pain I had for years."

"The copper-infused lumbar support is no joke. My back pain is gone after the first week. I've tried every cheap mattress out there. Should have bought the Serenity years ago."

Team Driver · Nashville, TN
"Got the Serenity for my Kenworth W900. Dual sided, built tough, fits the 42x80 bunk perfectly. This thing is built for drivers, not bedrooms. Best purchase I've made for my rig."

Kenworth W900 · Long Haul · Phoenix, AZ
"Cool to the touch cover is the real deal in summer. I run the southeast and it gets brutal. The Serenity keeps me sleeping cool even when it's 95 degrees outside the cab."

"Ordered 12 Serenity mattresses for our Mack Anthem fleet. Driver retention has actually improved since we upgraded the bunks. Sleep quality on the road matters more than people think."
