Shipping and returns
Returns, refunds and shipping follow Helix Sleep's own policy, not Coreplex's. Read it before buying, especially for opened, hygiene or final-sale items.
Other stores selling it
Coreplex counts another store's listing as the same item only when it shares a Shopify catalog ID or barcode with this one; lookalikes are shown as similar and never priced as equals. The live page runs that check now. AI agents can run it with the Coreplex MCP tools get_passport or compare_prices (product_url: https://checkout.helixsleep.com/products/midnight).
What Helix Sleep says

On a scale of 1-10 where 10 is the firmest, the Helix Midnight feels like a 6: cozy and soft with cushioned support.
