HOUSTON, July 15, 2025 /PRNewswire/ -- This wedding season, couples are busy finalizing guest lists, menus and registries, but they may be overlooking one of the most important parts of married life: sleep.

In a new survey conducted by Harris Poll on behalf of Mattress Firm, the nation's largest mattress specialty retailer, Americans say sleep plays a critical role in their relationships, and it's something couples should be thinking about before saying "I do." The Sleep Index reveals wedding advice, pain points and bedtime habits shaping modern relationships.

"We often think about wedding planning in terms of picturesque moments and to-do lists, but sleep is one of the most intimate and important parts of life together, and it's often overlooked" said Dr. Jade Wu, board-certified sleep psychologist and Mattress Firm Sleep Advisor. "This survey confirms what many know: better sleep leads to better relationships. So, for those about to tie the knot, now is the perfect time to plan for and talk about sleep - exploring habits and routines that work for early birds, night owls and everyone in between."

Couples Are Planning for Their Future Days, But Not for Future Nights
Even as they build new lives together, many couples admit they didn't think ahead when it came to sharing a bed.

Just 36% of couples included sleep-related items on their wedding registry, but in hindsight, 85% of married Americans say they would recommend adding them. Their top picks? Pillows (51%), bedding (50%) and a new mattress (37%).
When asked for their top pieces of sleep advice, married couples shared: never go to bed angry (64%), invest in a good mattress right away (57%) and talk openly about sleep preferences (54%).
Space matters, too. 65% of people planning to get married say they want a bigger bed, making a sleep system a smart and meaningful addition to a wedding registry.

The Bed Is Shared, But the Sleep Experience Isn't
Once couples move in together, mismatched sleep habits, tech routines and comfort needs can interfere with rest, and many aren't even talking about it.

Only 37% of couples who share a bed say they go to sleep at the same time, and nearly 1 in 5 say mattress firmness is an issue they've had to discuss.
Tech in the bedroom continues to cause friction. 49% of Americans, including 54% of men, wish they had a "no screens in bed" rule.
Interestingly, many blame themselves rather than their partner for poor sleep (44%), and 36% of married couples who share a bed say they almost never talk about their sleep habits.
Still, sleep has the power to bring couples closer. Married people overwhelmingly agree that better sleep leads to better relationships: 94% say it helps them be more patient and loving, 84% feel more emotionally connected when they share a bed, and 69% say cuddling helps them fall asleep.

A New Generation Is Rewriting the Rules of Rest
Younger couples are more likely to confront sleep challenges head-on and consider more flexible solutions when things aren't working.

Gen Z puts their ZZZs first. 43% say they would consider sleeping in separate beds for better rest, and 35% would consider ending a relationship over sleep issues.
They're also more likely to talk openly about it. More than half of Gen Z (55%) and Millennials (58%) talk about sleep habits with their partner at least weekly, compared to just 34% of Boomers.
Their top pain points? Snoring and temperature. Snoring is discussed by 36% of Gen Z and 31% of Millennials. Temperature discomfort is even more common, with 42% of Gen Z and 36% of Millennials citing being too hot or too cold in bed as an issue.
But it's not all friction, it's also connection. The majority of Gen Z (81%) and Millennials (82%) polled say cuddling with their partner helps them sleep better.

"When couples aren't sleeping well, it shows up in everything else. What this data really highlights is that a great relationship starts with great rest," said Megan Anderson, Director of Merchandising at Mattress Firm. "Whether it's choosing the right mattress or learning what works for both of you, we love helping people find sleep solutions that make sharing a bed feel easy."
