Best Foam: Lull Memory Foam Mattress
If you’re looking to purchase a new mattress, the first decision to make is what kind of mattress you want. For a medium-firm option that sleeps cooler than traditional memory foam, the Lull Mattress—made by one of several bed-in-a-box companies—is a great choice.
Unlike traditional foam mattresses, the Lull mattress is made with three unique layers of foam. The top layer is infused with a cooling gel that will help regulate your temperature so you don’t overheat, and the second layer provides a nice amount of support so you don’t feel like you’re “sinking in.” The firm base layer provides stability to keep your spine properly aligned and will prevent the mattress from sagging over time. There’s also a good amount of structure around the mattress edge, so it’s easy to get in and out of bed. This helps sleepers feel more stable when they’re near the side.
The company offers a 100-night trial period and within that time frame, unhappy customers will get a full refund.
