The Helix Midnight Luxe 2025 is a hybrid mattress with a quilted top, memory foam upper comfort layer, and a pocket coil support layer. It's an updated version of the Helix Midnight Luxe 2024 and offers a firmer feel. The materials are CertiPUR-US and GREENGUARD Gold certified.
It has a 'Medium' firmness level, making it well-suited for average and heavier side sleepers as well as lighter back and stomach sleepers. Lighter side sleepers may want a plusher mattress for better pressure relief, while heavier back and stomach sleepers may want a firmer option for better support. This mattress has moderate sinking and contouring, so you feel cradled but not hugged or enveloped. It's responsive and bouncy, so it's easy to move around and doesn't have a slow-moving memory foam feel.
Our Verdict
The Helix Midnight Luxe 2025 offers a great sleeping experience. It's a great option for sleeping with a partner, since its great motion dissipation means you won't feel most movements. It's also cooling enough for hot sleepers. The edges are sturdy, which increases the comfortable sleeping surface. This mattress also offers a very responsive feel, so you can easily move around in your sleep.

The Helix Midnight Luxe 2025 has a great cooling performance. It doesn't feel warm when you first get into bed and dissipates heat efficiently overnight. It's cooling enough to keep most people comfortable, including hot sleepers.
Cooling enough for hot sleepers.
The Helix Midnight Luxe 2025 has great motion dissipation. Motion dissipates decently quickly, so while you may feel a wobbling sensation with bigger movements, you won't feel like you're bouncing around whenever someone moves. It's even better at isolating motion. You'll only feel bigger movements near the source, and overall, movements aren't likely to wake you.
Movements aren't likely to wake you.
The Helix Midnight Luxe 2025 has fantastic edge support. The edges are reinforced with stiffer coils and form a slight ramp inward when you sit or sleep on the side of the mattress. You can comfortably sleep near the side of the bed, and the edges provide a sturdy surface for sitting or getting in and out of bed.
Sturdy edges so you can sleep comfortably near the side.
The Helix Midnight Luxe 2025 has great responsiveness. Although its comfort layer is made of slow-moving memory foam, the quilted layer also includes polyfoam and fiber fill. The mattress responds quickly to your movements, so you won't feel stuck in place or tightly hugged.
Great responsiveness, so you don't feel stuck in place.
The Helix Midnight Luxe 2025 is a fairly durable mattress. The weak point in terms of durability is the quilted top, which contains low-density, low-quality polyfoam and memory foam. These layers are prone to losing their shape and developing permanent indentations. The layers below are of better quality, however. The memory foam upper comfort layer is dense enough to reach the standard for good-quality, and so is the polyfoam transition layer. These layers will hold up to wear and tear longer, increasing the durability of the mattress overall.

Popular Mattress Comparisons
The Helix Midnight Luxe 2025 is a hybrid mattress with a great overall performance. It's a newer version of the Helix Midnight Luxe 2024 and has a slightly better overall performance in most respects, although it has a less responsive feel. It's cooling enough for hot sleepers, unlike some other 'Medium' mattresses like the Beautyrest Black and Puffy Lux. It has great motion dissipation as well. However, if you don't mind a memory foam mattress with slow responsiveness, the Casper Snow offers better cooling and better motion dissipation, with a similar medium firmness level.

The Helix Midnight Luxe 2025 is better than the Beautyrest Black for most people. They both have a medium firmness, a responsive feel, and moderate sinking and contouring. However, the Helix offers significantly better cooling, so it's much more suitable for hot sleepers. It has better motion isolation, so your partner's movements are less likely to wake you. It also offers better edge support, so it's more comfortabale to sleep near the side of the mattress.
The Helix Midnight Luxe 2025 and Nectar Premier Hybrid are both moderately bouncy and responsive hybrid options with medium firmness, but most people will prefer the Helix. The biggest difference is in edge support. While both mattresses have pocket coils built into the edges, the coils in the Nectar compress too easily to provide much support. The coils in the Helix, on the other hand, provide a lot of support, so you can sleep comfortably right next to the sides. The Helix is also more responsive and slightly more cooling. The one area where the Nectar comes out ahead is motion isolation, so if you sleep with a partner, you may prefer it since movement is less likely to disturb or wake you.
The Casper Snow and Helix Midnight Luxe 2025 have different strengths. Both have a medium firmness level, but you may prefer the Casper if you like feeling enveloped by your mattress, since it has a higher sinking level. The Casper offers much better cooling and motion isolation, but has slow responsiveness, so you may feel stuck in place. The Helix is much more responsive and has better edge support, so it's easier to get in and out of bed and more comfortable to sleep near the side of the bed.
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 Helix Midnight Luxe 2025 is better than the Puffy Lux for most people. They have a fairly similar feel, with medium firmness and moderate sinking and contouring, but the Helix offers better cooling, motion isolation, and edge support.
We've recently started testing mattresses. We use objective data and repeatable testing for key characteristics like firmness, cooling, and motion isolation, to ensure each mattress gets the same treatment. Since we buy all of our mattresses, we can tear them down layer by layer and isolate the mechanical properties of every component: quilted tops, foams, coils, and any special materials. Our approach gives us unprecedented insight into how each product design decision contributes to a mattress's overall performance and feel, and allows us to tailor our results to different body types and sleeping positions.
Test Results
The Helix Midnight Luxe 2025 is a 33 cm (13-inch) mattress, although ours measures a little more at 34.8 cm (13.7 inches). You may need deep-pocket sheets.
The Helix Midnight Luxe 2025 has a 'Medium' firmness level. This makes it suitable for average and heavier side sleepers as well as lighter back and stomach sleepers. Lighter side sleepers may want a softer mattress for pressure relief, while most back and stomach sleepers will prefer a firmer option for proper spinal alignment.
It's moderately bouncy. It doesn't feel extremely springy, but has a lively feel that makes it feel easy to move around in your sleep.
It has a balanced feel, with moderate sinking and contouring. You'll sink a bit into its upper layers, but won't feel enveloped. It cradles you instead of hugging you tightly.
It has great responsiveness. While it doesn't respond as quickly as some mattresses and doesn't have a noticeable 'push back' feeling, it adapts fast to your movements, so you don't feel stuck in place.
It has great motion isolation. You'll only feel bigger movements near the source, so when your partner rolls over, you'll feel a bit of movement in the lumbar, but not around your head or feet. Motion dissipates decently fast, but not as quickly as other mattresses, so you may feel that the mattress jiggles a bit with larger movements.
It has fantastic edge support. The sides of the mattress sink a bit when you sit there, but the edges form a ramp inwards, so you're pushed towards the middle of the mattress. While some mattresses' edges compress less overall, this means you won't feel at risk of sliding out of bed when sleeping near the side.
It has great cooling. It doesn't feel warm when you first get into bed, and continues to dissipate heat efficiently overnight. It's cooling enough to keep most people comfortable, including hot sleepers.
The cover is made of TENCEL, a fabric derived from wood pulp. It's not removable or machine-washable.
The left and right sides of the mattress are reinforced with tightly coiled 15-gauge springs. This helps give the mattress its fantastic edge support.
The quilted top includes three layers: fiber fill, polyfoam, and memory foam. The foams inside are soft, and you'll sink into the layer quite easily. The upper comfort layer is a thick layer of memory foam, and the heavier parts of you that compress the quilted layer will sink further into it. Below it is a polyfoam transition layer that's much firmer and prevents you from feeling the individual springs below.
Some of the foam is dense enough to be considered good quality, including the memory foam upper comfort layer and the polyfoam transition layer. These layers will resist sagging for longer than lower-density foams. However, the quilted top's polyfoam layer has a lower density (25 kg/m³ or 1.6 lb/cu.ft), and so does the memory foam layer (39.3 kg/m³ or 2.5 lb/cu.ft), making the quilted top a weak point in the mattress in terms of durability.
The quilted top is 2 inches thick overall and has three layers:
Fiber Fill: 1 cm/0.4 inches
Polyfoam: 2.3 cm/0.9 inches
Memory Foam: 1.7 cm/0.6 inches
You'll likely compress it fully and also interact with the memory foam upper comfort layer, which is also 5.1 cm (2.0 inches) thick. There's a 2.5 cm (1.0 inches) transition layer that prevents you from sinking into the springs, but you're unlikely to feel it directly because of the 12.6 cm (5 inches) of foam above it.
This mattress uses three different types of pocket coils in its support layer. The edges are reinforced with 15-gauge coils. While 15-gauge coils are made of thinner wire, which makes them softer, these coils are more tightly wound and offer more resistance. The head/foot and lumbar area of the support layer uses 13-gauge coils, which are firmer than the 14-gauge coils used for the rest of the layer. Overall, though, the spring layer firmness is still higher at the head/foot of the mattress. The difference is most noticeable for heavier users.
Together, the foams in the quilted layer are very soft, so you'll easily sink into it. You can see the separate results for the polyfoam upper layer and memory foam lower layer as well.
The memory foam upper comfort layer is medium-soft, so the heavier parts of your body that compress the quilted layer will sink into it as well, like your hips when sleeping on your side. The transition layer is very firm, so it prevents you from sinking in too far and feeling the individual springs.
The spring layer is firmer at the head/foot of the mattress and softer in the lumbar area. This allows your hips to sink further if you're sleeping on your side. The difference in stiffness depends on how much weight is applied to the springs: heavier users will notice more difference between the springs at the head/foot and lumbar area, while lighter people will perceive less difference. That said, the lumbar area is softer overall, despite the 13-gauge coils being used in the lumbar area and head/foot of the mattress.
The quilted layer is quite resilient, or bouncy, overall. This is mostly due to the bouncy polyfoam upper layer, since the memory foam lower layer in the quilted top is much less resilient. The memory foam upper comfort layer also has very little resilience, which is normal for the material and means it offers very little 'push back', so you sink into it. The transition foam is much bouncier.
The support spring layer is highly bouncy. Combined with the foam layers, including 5 cm/2 inches of very low-bounce memory foam, they help give the mattress its moderate overall bounciness.
