How We Test Every Mattress

Every mattress goes through our rigorous multi-step evaluation before we publish a single word. No shortcuts, no guesswork.

01

Unboxing & Setup

We order every mattress ourselves, document the unboxing experience, assess off-gassing, and track the full expansion timeline.

02

30-Night Sleep Trial

Real team members sleep on every mattress for a minimum of 30 nights, logging comfort, temperature, and support scores nightly.

03

Pressure & Support Mapping

We use body-pressure mapping tools to measure how each mattress distributes weight across back, side, and stomach positions.

04

Final Verdict

Data from every test feeds into our scoring model. We rate firmness, durability, value, and more — then publish our honest verdict.
