Have you seen this foam mattress?
It’s behind a lot of bad sleep, so we’ve got a warrant out.
REWARD: up to $799 off a GelFlex Grid mattress for anyone willing to turn in their old foam.
Case file: all-foam mattresses
“Big Mattress wants you to believe that foam’s great because it balances a wine glass. What’s that got to do with sleep? What does foam actually do? I’ll tell ya.”
— B.E.A. Sr. Analyst Ted Snooze
It sleeps hot

Waking up to soggy sheets? Here’s the culprit. Foam adapts by absorbing and retaining your body heat. All through the night, baby.
It adapts slowly
It adapts slowly
You roll over on foam, suddenly you’re sleeping on a rock that takes ages to adapt. Now you’re up in the middle of the night. Sorry.
It isn’t durable

That bed-in-a-box all-foam mattress collapses fast, leaving you with a poorly aligned spine and a rude awakening in the morning.
Editor’s note
Our friend Ted Snooze over at the B.E.A. has a bone to pick with foam, but we’ll note that it has some applications. It’s great for insulating your house, mascot costumes, and use in mattresses as a supportive layer — in other words, when it’s not the surface you’re sleeping on.
GelFlex Grid 101
Our SleepScore Labs validated layer puts traditional mattress tech to shame, and while it feels like magic, it’s really the result of modern engineering. Here’s a breakdown.
SLEEPING HOT?

Frequently asked questions
Unlike foam, whether it's in a mattress, pillow, or seat cushion, the GelFlex Grid is instantly adaptive. There's no lag time between the Grid and your movement. While foam slowly conforms and slowly recovers, the GelFlex Grid responds in real time, whether you're sleeping, resting your head, or sitting at a desk all day. It also helps regulate temperature more effectively than foam. Traditional foam can absorb and trap body heat, which may contribute to overheating during the night, while the open-channel design of the GelFlex Grid allows excess heat to pass through and away from your body, helping you stay comfortably temperature-neutral.
It can. Memory foam's slow-to-recover structure can let hips and shoulders sink too far, throwing your spine out of alignment overnight. The GelFlex Grid is built to do the opposite — it flexes precisely under pressure points while staying supportive everywhere else, which is part of why it's been shown to reduce sleep-interfering pain by up to 63%.*

Memory foam is dense and slow to respond; latex is more responsive than foam but still lacks targeted pressure relief. The GelFlex Grid is engineered from 1,400+ open-air columns that buckle precisely under concentrated weight — cradling pressure points instantly while staying breathable, in mattresses, pillows, and seat cushions alike.
Yes. Foam is dense and tends to trap heat close to the body. The GelFlex Grid is built as an open, breathable structure that lets warm air move away instead of building up. Plus, the Grid material itself is designed to transfer heat rather than retain it, helping prevent heat from lingering where you're sleeping, sitting, or resting your head. The result is a cooler, more comfortable experience that can help people stay up to 4x cooler* than with traditional foam.

Memory foam pillows are known for sleeping hot and slowly springing back into shape. Purple GelFlex Grid pillows stay cool and respond instantly, so you're not waiting on the material to catch up to your head and neck, or constantly flipping your pillow to a cool side night after night.
Yes. Every Purple product is made with non-toxic, hypoallergenic materials certified Clean-Air Gold, and any foam layers we do use are CertiPUR-US® certified. No fiberglass, ever.
