The Helix Midnight 2024 is a mid-range bed-in-a-box mattress. It has a hybrid design with a support layer made of individually wrapped pocket coils, a polyfoam transition layer, and two comfort layers: a polyfoam layer and a memory foam layer on top.
It has a medium level of firmness, making it suitable for average to lighter back and stomach sleepers and average to heavier side sleepers. Heavier back and stomach sleepers may prefer a firmer model to keep the spine aligned, while lighter side sleepers may prefer something plusher, so their hips and shoulders can sink far enough in, relieving pressure. This mattress is moderately bouncy, and while you don't sink into it much at all, it offers a fair amount of contouring, so you feel the surface mold around your body.

The Helix Midnight isn't a durable mattress. It doesn't contain any dense, good-quality foam layers; instead, it uses less dense, lower-quality foam. The mattress will lose its shape, sag, and develop permanent body impressions faster compared with mattresses that use higher-quality materials.

The Helix Midnight is very good at cooling. It keeps you very cool overnight, transferring a lot of heat away from you, so you don't wake up overheated. However, its cooling is just decent during the first hour of the night, so if you have trouble falling asleep in the heat or if you sleep hot in general, you may need an option that transfers more heat away from you at the beginning of the night.

Warms up somewhat at the beginning of the night.

The Helix Midnight offers satisfactory motion isolation. Most movement is noticeable near the source, and while this mattress is pretty good at keeping motion localized, you can still feel smaller shifts from farther away. When your sleeping partner rolls over, for example, you feel it mainly in the lumbar, but a little bit at the head and foot of the bed as well. Motion takes a moment to dissipate as well, making it more noticeable. While its performance should suffice for most people, partnered and light sleepers may prefer something that dampens motion more effectively.

Motion isolation may not be effective enough for partnered or light sleepers.
Likely too firm for lighter side sleepers and too soft for heavier back and stomach sleepers.
The Helix Midnight delivers great responsiveness. When you compress the mattress, it pushes back, recovering its shape pretty quickly. This responsiveness makes it easy to move around, so you don't feel constricted or stuck as you try to change sleeping positions.
Great responsiveness makes it easier to shift sleeping positions.

Differences Between Sizes And Variants
The Helix Midnight 2024 is available in Twin, Twin XL, Full, Queen, King, California King, Short Queen (60" x 74"), and RV King (72" x 80"). Two upgrades are available for this mattress: the GlacioTex Cooling Pillow Top, meant to be instantly cooling, and the ErgoAlign Layer, meant for people with lower back pain. We tested the Queen-sized 2024 model with no additional upgrades, and our review is only valid for that variant. See the first label and the second label for our unit. There's also a newer version of this model, the Helix Midnight 2025.
If you encounter a different variant or have experience with one that performs differently, let us know in the comments.
Popular Mattress Comparisons
The Helix Midnight 2024 is an impressive mid-range hybrid bed-in-a-box with a medium firmness level. It's an outdated version of the Helix Midnight 2025, which has redesigned foam layers. The company also makes the Helix Midnight Luxe 2024, which was also redesigned. Compared to the Luxe model, the Midnight performs really well. Despite a much lower price tag, it provides better edge support, so you can sleep comfortably no matter how close to the side you are, and it's more cooling.
Compared to other hybrids, this mattress has great, though not outstanding, performance. Its edge support is its strongest aspect, outperforming most other hybrid options. You can sleep right next to the side without worrying about falling off. While it's not quite cooling enough for hot sleepers, its cooling performance rivals that of the much pricier Stearns & Foster Lux Estate as well. On the other hand, its motion isolation is a bit below average. You'll feel more movement on this mattress compared to other hybrids, like the Nectar Classic Hybrid, so it's not the best option for couples. Still, it's a solid option if you're not a particularly light sleeper.

The Helix Midnight Luxe 2025 is an updated version of the Helix Midnight 2024. It has a different feel and a slightly better performance overall. The 2025 version has a medium firmness level, so it's a little firmer than the medium-plush 2024 version. It offers better cooling as well as marginally better edge support and motion dissipation. However, it uses less resilient memory foam in its comfort layer and also includes a layer of memory foam in its quilted layer, which results in a less responsive mattress.
The Sealy Posturepedic Hybrid and the Helix Midnight 2024 are evenly matched overall, but they have different strengths, and you may prefer either depending on your priorities. The medium-plush Sealy has better motion dissipation, so it's the better bet if you have a sleeping partner who tosses and turns. It's also more responsive, making it easier to move around. The Helix has a medium level of firmness. It comes out ahead in terms of edge support, making it even more comfortable to sleep next to the sides. The Helix is slightly more cooling, too, though neither option is ideal for hot sleepers.
The Helix Midnight Luxe 2024 and the Helix Midnight 2024 are very evenly matched, and for most people, the additional cost of the Luxe version won't be worth it. The Midnight Luxe is a medium-plush model with improved motion dissipation, making it a good option for couples. It's more responsive as well, so while it isolates motion, it still supports your movements. On the other hand, the Midnight, a slightly firmer medium model, has sturdier edges, so you can sleep right next to the sides without worrying about slipping off. It's more cooling, too, and while it's not quite cooling enough for hot sleepers, it's efficient enough to keep most people cool. Overall, unless motion dissipation is particularly important to you, the Helix Midnight is likely the better value.
The Helix Midnight 2024 is a better option than the Saatva Classic for most people. Both mattresses have a medium level of firmness, but the Helix comes out ahead in a few areas. The biggest difference is in edge support. On the Helix, you can sleep right next to the edge without worrying about slipping off. It's more cooling, too, and while it's not quite cooling enough for hot sleepers, it's a significant improvement over the Saatva. The Helix has slightly better motion isolation as well, though it's probably not a big enough difference to be noticeable. The one area where the Saatva comes out ahead is responsiveness. It responds more quickly when compressed, making it easier to move around on. Still, unless responsiveness is your top priority, the Helix is a better choice.
