The details: Before ordering a Helix mattress, you take a brief survey on their website that uses your height, weight, usual sleeping position, and preferred mattress firmness to determine your ideal mattress. I sleep on my side and prefer a medium-to-firm mattress, which gave me the Helix Midnight, a 12-inch mattress with medium support and a hybrid foam-spring composition. This also happens to be the brand’s best-selling mattress.
Overall, I loved it—but I had some difficulties with its delivery. The box that got dropped off outside my door had no handles, and it was heavy, so I had to enlist two of my roommates to help me hoist it up the stairs to get to my bedroom. This took a long time, not because it was heavy (though, at about 70 pounds, it was), but because the box didn’t have a great place to grip and kept slipping out of our hands. Once I got it to my room, though, the unboxing process was pretty easy (I had to snip off a lot of plastic wrap, but that’s common in the boxed mattress experience). There was also a strong chemical smell on the mattress that stuck around after I unwrapped it, but that dissipated a little bit each day and went away fully in about a week.
That said, I slept really well on the Helix Midnight. It has a perfect medium-firm feel, with some give when you lay down on it, but a distinctive sensation of deeper support at its core. I’ve always been a side sleeper, but on my old spring-filled mattress, I would sometimes wake up with a sore, crooked-feeling back and aches in my hips where the springs had dug into them. On the Midnight, however, I felt alignment on my side when I woke up, and, because the mattress’s interior coils are surrounded by memory foam, no piercing pains in my hips. It felt comfortable if I ever rolled over to my back or stomach, too. I also tend to sleep hot (and my apartment doesn’t have air conditioning), so I was pleased that the mattress didn’t retain too much of my body heat, even when I was sweating in the night. All in all, it’s a great mattress at a decent price, particularly if you’re a side sleeper.
