What is the 3-2-1 sleep method? It’s a simple bedtime routine designed to help you wind down and get ready for better sleep. Here’s how it works:

3 hours before bed: eliminate food & alcohol
2 hours before bed: wrap up stressful tasks
1 hour before bed: step away from screens

Tired but your brain won’t shut off? 😴 Give the 3-2-1 sleep method a try.

Why are you still tired after 8 hours of sleep? 😴 Kylethesleepexpert explains:
💤You might be getting enough sleep, but not enough quality sleep.
💤Things like room temperature, noise, an unsupportive mattress and subtle sleep disruptions can leave you feeling exhausted, even after a full night in bed.
💤If you're waking up tired every morning, it may be time to take a closer look at your sleep environment.

From your mattress and pillow to your bedroom setup, every detail plays a role in helping you get deeper, more restorative sleep—because 8 hours in bed doesn't always mean 8 hours of quality sleep.

Shout-out to Sleep Expert Kyle in Toms River, MN, for the tips!

What type of mattress is best for back sleepers? 😴

✅ Choose a mattress that helps keep your spine in a neutral position and provides support where you need it most.
✅ Look for pressure relief that cushions your shoulders, hips and back while keeping you comfortably supported.
✅ Many back sleepers prefer a medium, medium-firm or firm feel that balances comfort and support.
🛏️ Memory foam, hybrid or innerspring? The right mattress type comes down to finding the combination of support, pressure relief and comfort that works for you.

When you’re ready to upgrade, stop by your local store and let our Sleep Experts guide you to your perfect match.
