9. Layla Sleep Memory Foam Mattress
The Layla Sleep Memory Foam Mattress is unique due to its dual firmness feature – one side is soft while the other is firm, catering to different sleep preferences. It also features copper-infused memory foam that helps regulate temperature and provides antimicrobial properties.
Users particularly appreciate this mattress for its pressure relief and how well it contours the body. The 120-night trial and lifetime warranty further emphasize the brand’s confidence in its product.
- Flippable Firmness: The Layla Memory Foam Mattress is firm on one side and soft on the other, so you have two chances to find the right feel for you. If your firmness preferences change over time or if you’re sleeping with a partner who wants a different feel, just flip the mattress to the other side and see if that suits you. Layla was one of the first makers of a flippable copper infused memory foam mattress, so we’ve had years of experience and time to perfect this technology.
- Copper Cools: The copper cooling technology in our mattresses incorporates gel encapsulated copper particles mixed into the memory foam. When you lay down on a Layla copper infused mattress, the tiny copper-gel particles condense together forming a thermal superhighway to transfer heat through the condensed particles so it can be pulled away from your body. With this efficient and effective heat transfer technology, we prevent a build up of excessive heat under your body which makes you cooler.
- Copper Supports: Those copper-gel particles in the memory foam do a lot more than just keep you sleeping super cool, they adapt to your body weight to support you in all the right places. When the copper gel particles in the mattress condense under body weight, they react with a firming response. The more weight that presses down, the more the copper particles push back. So you get more support where your body pushes into the mattress and more give where your body does not.
- High Quality Foam & Fabric: Any mattress manufacturer will tell you that copper infused memory foam is a more costly component than traditional memory foam. Why does Layla use this high end foam and not jack up the price? Because at Layla we put value and pride before profits. We set out to do something better for sleepers, to build something we can be proud of and feel confident recommending to our own friends and family.
- Made in The USA: Every single Layla Memory Foam Mattress is crafted right here in the United States by a US workforce. It’s important to us to support the US economy as much as possible, but there are other benefits to being made in America. Our mattresses are made to order, when you place your order, we begin crafting the mattress that will land in your home. Why is this better? Memory foam can degrade over time when it’s compressed and boxed for shipment which can lead to poor performance.
