If you’ve been eyeing the Purple mattress but waiting for the right time to upgrade your sleep game, Costco’s got the Purple Purplerenew 11″ King Gel Grid Mattress in stock right now. This is the real deal—not a Costco-exclusive knockoff, but Purple’s actual GelFlex Grid technology in a king size.
This mattress features Purple’s signature 2-inch GelFlex Grid layer that’s designed to cradle pressure points while supporting everything else. The 11-inch profile gives you that premium feel without being so tall you need a stepstool to get into bed. It’s meant to sleep cool, stay supportive, and adapt to different sleeping positions throughout the night.
Here’s the honest take: Purple mattresses have a devoted following for good reason—that grid really does feel different from traditional memory foam or springs. But they’re also pretty firm, especially if you’re used to plush mattresses. The “Purplerenew” name suggests this might be a refreshed or specific model line, so make sure you’re clear on the return policy if you’re uncertain about the feel.
