Frequently asked questions
Most back sleepers do best on a medium to medium-firm surface; supportive enough to keep the spine neutral, with enough give to relieve pressure at the lower back and hips. If you’re on the lighter side (under 130 lbs), a slightly softer feel may work well; heavier back sleepers often benefit from firmer support found in our Restore and Rejuvenate collections. The best way to know is to try it. Test a Purple mattress in store and take advantage of Purple’s 100-night trial.
Neither extreme is the answer. A mattress that’s too firm can create pressure points at the hips and lumbar; too soft, and your hips sink out of alignment. Back sleepers with pain tend to sleep best on a surface that maintains spinal alignment while adapting to natural body contours. Purple mattresses, which feature the GelFlex Grid®, are designed to do both — supporting where you need it, relieving pressure where you don’t.
The GelFlex Grid® is engineered to flex for comfort and support for alignment — it adapts instantly as you move, relieving pressure at key points while keeping your spine in a neutral position throughout the night. Unlike traditional foam that compresses uniformly, the GelFlex Grid responds to your body’s shape, so back sleepers get the support they need without the stiffness that can come with a firm foam mattress.
It comes down to how much pressure relief you need and how you like your mattress to feel. Back sleepers who want a balanced medium feel often gravitate toward the Restore® Hybrid Mattress or The Purple Mattress®. Those dealing with back pain or discomfort tend to prefer the RestorePlus® or Rejuvenate collection, which offer advanced pressure relief alongside responsive support.

Yes — and many back sleepers find that a slight incline reduces pressure on the lower back. All Purple hybrid mattresses are compatible with Purple’s adjustable bases, letting you dial in exactly the position that works best for your body.
Yes — and Purple mattresses are particularly well-suited for combination sleepers. The GelFlex Grid® adapts instantly as you shift positions, relieving pressure at the shoulders and hips when you're on your side while maintaining spinal alignment when you're on your back. If you split time between both positions, the RestorePlus® Hybrid or Rejuvenate collection offer the most adaptive pressure relief for the transition.
