Our Testing Team’s Take

Our testing team has spent years developing a comprehensive methodology to evaluate mattresses. We use a wide range of tools and technologies in our Seattle Test Lab, including pressure-mapping pads to assess how the mattress distributes and supports weight, heat sensors to track temperature regulation on the surface, and motion sensors to measure how much movement transfers across the mattress.

Our team members represent a wide range of body types and sleep position profiles. After finishing our lab tests, we’ll bring mattresses home for additional testing in our own bedrooms. This combination of objective data and personal experience helps us identify which mattresses perform best for different types of sleepers.

Our Verdict

The Helix Midnight Luxe and Nolah Evolution 15 share many similarities. Both are hybrid mattresses with foam comfort layers and coil support systems, but subtle differences in feel and construction can make one model more suitable for certain sleep positions and body weights than the other. We also noticed slight differences with performance areas like motion isolation, pressure relief, and temperature regulation.

“I love the feel of the Evolution’s tufted pillow-top. Coupled with the fact that it’s a really tall mattress, it definitely gives the bed a luxurious vibe. The surface feels plush without being too soft, but that said, the foam layers still conform a bit too closely for my liking.”

The Helix Midnight Luxe offers a balanced, medium firm (6) feel with moderate contouring and sturdy, reliable support. The mattress performs especially well for side sleepers thanks to its cushioning and pressure-relieving abilities, and couples should appreciate the thick foam layers that limit motion transfer. However, those who prefer springier beds with extra surface bounce should opt for a more responsive model. 

The Nolah Evolution 15 stands out for its pressure-relieving comfort system and cooling features, including breathable organic cotton and high-tech cooling fibers. With three firmness options available, this mattress suits a wide range of sleepers and body types.

“This Helix Midnight Luxe felt comfortable right away. It has just enough contouring to ease pressure points, but still keeps your body supported and your spine aligned throughout the night. As a side sleeper, I love the fact that I woke up in the morning without sore shoulders.”

Ultimately, side sleepers up to 230 pounds will probably prefer the deeper contouring of the Helix Midnight Luxe, or the medium (5) and medium firm (6) Nolah Evolution 15 models. Those seeking a more robust and supportive mattress should consider the firm (8) Evolution 15 instead.

Construction and Materials

Helix Midnight Luxe Breakdown

The Helix Midnight Luxe is a 13.5-inch hybrid mattress with a medium firm feel (6 out of 10 on our 10-point firmness scale). It features a quilted pillow-top designed for surface-level cushioning, and a moisture-wicking Tencel cover. For an extra fee, you can upgrade to a cover made of GlacioTex, a cutting-edge fabric engineered to release body heat when it comes into contact with your skin.

Under the cover, memory foam and polyfoam layers provide dense cushioning and contour closely to the body. These layers help relieve pressure at the shoulders and hips — a key benefit for side sleepers. These layers also absorb movement and isolate motion.

The support core consists of zoned pocketed coils, which provide targeted support beneath the midsection while allowing more give around the head, shoulders, and legs. A high-density foam base gives the mattress solid overall stability.

Nolah Evolution Breakdown

The Nolah Evolution 15 is a 15-inch hybrid mattress available in medium (5), medium firm (6), and firm (8) designs. This range makes the mattress suitable for a broad range of sleeper types.

A standout feature is proprietary AirFoamICE foam, an open-cell material engineered to contour to the body and alleviate pressure like memory foam, but without hugging as closely or retaining too much heat. All of the foam layers are encased in a sleek Euro-top cover made of organic cotton and cooling ArcticTex fibers.

A zoned coil system provides targeted support and helps maintain spinal alignment. Reinforced perimeter coils bolster stability around the edges, while air circulates steadily through the open support system to keep the mattress cool. This combination of deep cushioning and breathability allow the Nolah Evolution to excel at both pressure relief and temperature regulation.

Mattress Sizing and Weight

Both mattresses are available in the six standard sizes: twin, twin XL, full, queen, king, and California king, making them compatible with most bed frames and foundations. Additional options include a short queen and RV king for the Midnight Luxe, both of which are intended for on-the-road use, and a split king size for the Nolah Evolution catering to couples who use adjustable beds.

The Helix Midnight Luxe has a profile of about 13.5 inches, while the Nolah Evolution 15 measures 15 inches thick. Due to its taller build, the Nolah may require deep-pocket sheets to ensure a secure fit, whereas the Helix is more likely to work with standard fitted sheets.

These Helix and Nolah models are on the heavier side because of their hybrid designs, which combine densely layered foams and steel coil systems. Moving or setting up either mattress typically requires two people. Their weight can also make routine tasks like rotating the mattress more challenging.

Performance Ratings

While both mattresses perform well across the board, each has distinct strengths that may appeal to different types of sleepers. The Helix Midnight Luxe has a slight edge in the motion isolation category thanks to its memory foam comfort layers, which absorb movement effectively and prevent transfer on the surface. This makes the mattress a solid option for anyone who is easily disturbed by their sleep partner’s movement during the night.

The Nolah Evolution 15 stands out for pressure relief, especially with medium and medium firm models. Its thick comfort system and proprietary foam provide deeper cushioning around common pressure points like the shoulders and hips, which side sleepers in particular are likely to appreciate.

When it comes to temperature regulation, the Nolah Evolution 15’s breathable construction and materials help to dissipate heat from the surface. This allows the mattress to sleep cooler than many competing hybrid models. The Helix Midnight Luxe also regulates temperature well, but it may retain slightly more heat due to its memory foam layers. 

Both mattresses feature reinforced edge support, giving sleepers a stable feel when sitting or lying near the perimeter of their bed. That said, the Nolah Evolution’s coil system provides slightly more perimeter support. This can be beneficial for couples and solo sleepers who use the full surface of their mattress.

Ease of movement is another area where both mattresses perform at roughly the same level. Since each of these mattresses contains thick foam layers, you may encounter some resistance when moving on its surface. The firm Nolah Evolution 15 is least likely to sink excessively and make you feel stuck.

Mattress Pricing

Both mattresses fall into the luxury hybrid category and are similarly priced, though frequent promotions and seasonal discounts can significantly lower the final cost.

The Helix Midnight Luxe and Nolah Evolution both come with a 120-night sleep trial, giving sleepers ample time to decide if their mattress is the right fit. Both brands also back their mattresses with lifetime warranties. Shipping is free within the contiguous United States for both models, and White Glove delivery — which includes in-home setup and old mattress removal — is available for an additional fee.

What Customers Are Saying

Customers credit both mattresses with a balance of comfort and support, but feedback highlights different strengths that align closely with each model’s specific design. Helix Midnight Luxe owners frequently point to strong pressure relief and minimal motion transfer, making it a popular choice for people with back pain and couples. Many also appreciate its balanced feel, noting that it offers enough contouring to cushion pressure points without sacrificing support, which helps it perform well across multiple sleep positions.

Nolah Evolution 15 customers, on the other hand, often emphasize its plush cushioning and standout temperature control. Side sleepers in particular report fewer pressure points and an overall improvement in their sleep quality. That said, some users note that the Nolah can feel softer than expected — especially the medium soft version — while others say the Helix Midnight Luxe feels slightly firmer than they anticipated.

Bottom line: When choosing a mattress, the Helix Midnight Luxe and Nolah Evolution 15 are both strong luxury hybrid options backed by positive customer reviews. However, they cater to slightly different sleeper profiles. The Helix Midnight Luxe is a better fit for sleepers who want balanced support, strong motion isolation, and a medium firm feel. The Nolah Evolution 15 is a better choice for those seeking deeper pressure relief, more breathability, and the flexibility of multiple firmness options.
