Introducing LiftCore™ Support Technology: Why We're Calling It a Support Core, Not an Insert

Crown Lift® is the patented pillow support system that slides inside any pillow to stop it from going flat overnight. The technology behind it is called LiftCore™ Support Technology, and the physical piece that goes inside your pillow is called a support core — not an "insert."

If you've seen Crown Lift referred to as an "insert" in older content, that's the same product. We're updating our language to better reflect what the product actually does: it doesn't just sit inside your pillow, it actively lifts and supports it from within.

LiftCore™ Support Technology is the patented system behind Crown Lift®. It's built around a simple idea: pillows lose their support over time, and your neck feels it long before you notice the pillow has changed shape.

LiftCore™ works by adding a firm, adjustable support core underneath the pillow you already own and love. Instead of replacing a pillow that's lost its shape, LiftCore™ restores the lift and support it used to have — while keeping the surface, feel, and fabric of your favorite pillow exactly the same.

The system comes in three heights — 1", 2", and 3" — so it can be customized to the person, the pillow, and the sleep position, rather than forcing a one-size-fits-all fix.

Early on, Crown Lift's support piece was described as an "insert." It's accurate in a narrow, technical sense — the piece does insert into a pillowcase — but it doesn't describe what the product actually does once it's in there.

"Insert" describes a motion. "Support core" describes a function.

The support core is the part of the LiftCore™ system that does the actual work: restoring structure to a pillow that has compressed, flattened, or lost its shape. Calling it a support core makes that function clear immediately, rather than requiring an explanation of what the "insert" is for.

This is a naming update, not a product change. If you've purchased Crown Lift, own an older box, or have seen it referred to as an "insert" in a review, article, or older page — it's the same patented product, same LiftCore™ technology, same 30-night full refund guarantee. Only the terminology has been updated.

"Insert" may still appear in technical, legal, or patent documentation, where precise mechanical language is required. In everyday use — packaging, the website, and customer-facing content — "support core" is the correct, current term.

Crown Lift® uses LiftCore™ Support Technology to add a support core to the pillow you already own, restoring the lift and support it had when it was new — without replacing the pillow itself. Whether you've seen it called an "insert" or a "support core," it's the same patented system, backed by the same 30-night full refund guarantee.
