Independent Study Confirms Purple Mattress Effects on Sleep

Across two 10-week, in-home studies evaluating Purple's Essentials and Restore mattress collections compared to the research participants' sleep on their original mattresses, SleepScore Labs analyzed more than 3,300 nights of objective and self-reported sleep data. The results reaffirm the GelFlex Grid® as a uniquely effective comfort solution for people whose sleep is impacted by aches and pains.

Participants reported significant reductions in the degree to which nighttime pain interfered with their sleep, including a 68% pain reduction on Purple Essentials and a 63% reduction on Purple Restore. Enhanced sleep and reduced pain are key drivers of daytime well-being. Scientific research has shown that when these basic pillars improve, people often report better cognitive performance, greater vitality, and improved overall wellness.

"Participants reported substantial reductions in the impact of pain on their sleep, alongside changes observed in the sleep tracking data," said Dr. Sharon Danoff-Burg, Senior Principal Research Scientist at SleepScore Labs. "This combination of objective and subjective improvements speaks to the meaningful comfort and support delivered by the Purple Essentials and Purple Restore Mattresses containing GelFlex Grid technology."

Both studies demonstrated objectively measured improvements in participants' sleep, compared to when sleeping on their original mattress, including:

—Essentials users fell asleep 8% faster and woke up 6% less often.

—Restore users spent more time in deep sleep (+3.5 hours per month) and slept longer (+7 hours per month), along with better sleep quality (+3%) and efficiency (+2%).

Participants also reported gains in how restored and satisfied they felt each morning:

—Feeling well-rested: +96% (Essentials), +174% (Restore)

—Self-Reported sleep quality: +90% (Essentials), +170% (Restore)

—Sleep satisfaction: +127% (Essentials), +214% (Restore)

—Restore users also reported a 204% increase in their ability to sleep through the night without tossing and turning

Because participants were asked not to change their nighttime routines or sleep environments other than the mattress, the results point to the meaningful impact of the mattress itself.

"These findings reinforce what we hear from Purple sleepers every day," said Rob DeMartini, Chief Executive Officer at Purple. "Our mattresses, featuring the GelFlex Grid, deliver powerful and measurable improvements in sleep and pain. Independent scientific validation confirms that our technology helps people fall asleep easier, sleep better through the night, and experience truly transformative rest. That is our mission: Less pain. Better sleep."

Purple's patented GelFlex Grid was originally developed for medical applications to reduce pressure and support patients with limited mobility. The technology is now central to Purple's mattress designs, offering a unique combination of pressure relief, alignment, and temperature balance.

"We are pleased to see such strong and consistent outcomes from Purple's mattresses with GelFlex Grid technology," said Colin Lawlor, CEO of Sleep.ai. "These results highlight the role that better-designed sleep surfaces can play in reducing pain-related sleep disruption and supporting deeper, more measurable rest. It's a strong validation of Purple's approach and a compelling example of how thoughtful innovation can improve people's nighttime recovery."

Interested partners who want to learn more about the findings can visit the Purple showroom during Las Vegas Winter Market on Monday, January 26, where the Head of Business Development from Sleep.ai will be available to discuss the study and answer questions.
