Why an Adjustable Base Changes Everything

Symphony Sleep Elegance ES600 Adjustable Base

Colorado's active lifestyle demands real recovery, and a flat mattress can only do so much. An adjustable base lets you dial in your perfect sleep position: elevate your head to ease snoring or acid reflux, raise your legs to relieve lower back pressure, or settle into Zero Gravity mode for the kind of deep, restorative sleep that fuels your next adventure.

At Sleep Basil, we've spent 25+ years helping Denver sleepers find the right setup for their body and their lifestyle. We carry a carefully curated lineup of Symphony Sleep adjustable bases — from simple, solid foundations to premium German-engineered smart bases with massage, app control, and active lumbar support. Come try them in our showroom, or order online with free delivery and haul-away within 50 miles.

Frequently Asked Questions About Adjustable Bases

Can an adjustable base really help with back pain?

Yes, and we've seen it firsthand with hundreds of customers. Elevating your head and legs slightly takes pressure off your lower back and promotes better spinal alignment while you sleep. For customers recovering from back surgery or dealing with chronic pain, pairing an adjustable base with the right mattress can be genuinely life-changing.

What is Zero Gravity mode? 

Zero Gravity is a preset position that elevates both your head and legs simultaneously to evenly distribute your body weight — reducing pressure on your spine, improving circulation, and promoting deeper, more restorative sleep. It's one of the most popular features on our ES500 and ES600 bases.

Can couples use different positions on the same bed?

Absolutely. Our Split Cal King options on the ES500 and ES600 allow each side of the bed to adjust independently, ideal for couples with different sleep needs or preferences.

Do adjustable bases work with my current mattress?

Most memory foam, latex, and hybrid mattresses are compatible with adjustable bases. When you visit our showroom, our owners will make sure your base and mattress are a perfect match before you buy anything.

Do you offer financing?

Yes. We offer no-interest financing through Shop Pay, Synchrony, and Klarna -so you can invest in better sleep without the upfront pressure.

Do you deliver and set up adjustable bases?

We offer free delivery, setup, and old mattress haul-away within 50 miles of our Denver store. We handle everything so you don't have to.

Can I try an adjustable base before I buy?

Of course, our Denver showroom is designed exactly for that. Come in, take your time, try the different positions, and let us help you find the right fit. No pressure, no hovering salespeople. Just honest guidance from the owners.
