I've tested over 34 flippable mattresses in the past four years, and most of them are gimmicks. The Layla is not. It's one of the few beds where both sides are actually worth sleeping on — and that changes the value equation completely.
That said, Layla leans hard into the "copper-infused cooling" angle in their marketing. Copper does conduct heat, but I'll tell you exactly what that means in practice versus what the ads imply. If you want to see how it stacks up against the field, the best mattress of 2026 roundup puts it in context. For head-to-head comparisons with specific competitors, the direct comparisons directory is where I'd start.
How the Copper Cooling Actually Works
Layla's marketing makes copper sound like air conditioning. It's not. What copper does is conduct your initial body heat away from the surface faster than standard foam — I measured the soft side running about 2°F cooler at the 30-minute mark compared to a non-infused foam bed I tested the same week.
Over a full 8-hour co-sleeping session, that gap narrows. Memory foam still traps heat over time, copper or not. It's a real advantage for the first half of the night, less so by morning. That's an honest read — not what the product page says, but what I found.
Pressure Relief and Which Side to Sleep On
If you wake up with hip or shoulder pain, the soft side is genuinely good. I found it cradles pressure points without that stuck-in-quicksand feeling some memory foams give you. Side sleepers especially will notice the difference.
Stomach sleepers and heavier back sleepers should flip it. The firm side keeps your hips from sinking past neutral, which is exactly what that position needs. Two sleepers with different preferences sharing one bed is where this mattress earns its price.
