Hi Reddit!

My name is Derek! I’ve been testing mattresses since 2014 and over the years I’ve tested 340+ different mattresses.

I am the original owner & Founder of Sleepopolis, where I operated it from 2014 to 2017.

In 2021, I launched a new platform at to test mattresses. At NapLab I developed a battery of objective & data-driven tests to analyze and score mattresses. includes:

• Thermal imagery to assess cooling / heat retention

• Accelerometer to measure motion transfer

• 5 factor weighted equation to assess sex performance

• Video / photo analysis to take precise & objective measurements for sinkage, material responsiveness, edge support, and bounce

• In addition to other data-driven tests

NapLab’s aim is to create the most objective, transparent, and helpful mattress reviews so our readers can make the most informed decision about the mattress that's best for them.

Happy to answer any questions about mattresses, sleep, NapLab, the industry, or anything else on your mind 🙂
