Helix Midnight Mattress with GlacioTex Pillow Top - Twin XL Cooling Memory Foam Hybrid Bed, Medium-Firm Support

Product Overview

The Helix Midnight Mattress measures 80 inches long by 38 inches wide with a 12.5-inch thickness in the Twin XL size shown. It weighs approximately 70 pounds in this configuration. The mattress features a four-layer construction combining foam and coil systems. The top layer is a GlacioTex cooling cover that provides immediate cool-to-the-touch sensation. Beneath this lies SupremeSupport 2.5 Memory Foam, which Helix claims offers 2.5 times more cushioning than standard memory foam. This layer works with additional pressure-relieving foams to contour to the body's curves. The support core consists of hundreds of individually wrapped steel coils that provide responsive support while limiting motion transfer. Reinforced side perimeters enhance edge support and durability. The mattress arrives compressed, rolled, and shipped in a box for convenient delivery and setup. It requires no special tools for unboxing and typically expands to full size within hours. The white and brown color scheme offers a neutral aesthetic suitable for various bedroom décors. Care involves regular rotation and spot cleaning as needed. The medium firmness level (6/10) makes it versatile for different sleeping positions, though it's particularly marketed toward side sleepers who need pressure relief at shoulders and hips.

Design & Build

The Helix Midnight Mattress features a thoughtful four-layer hybrid construction designed for both comfort and support. The topmost layer is the GlacioTex cooling cover, which provides immediate temperature regulation with its cool-to-the-touch surface. This cover wraps around the entire mattress and features a plush pillow top design that adds cushioning without excessive loft. Beneath this lies the SupremeSupport 2.5 Memory Foam layer, which Helix specifically engineered for enhanced cushioning properties. This memory foam contours to the body's pressure points while slowly returning to its original shape. Additional foam layers work in conjunction with the memory foam to create a balanced medium feel. The support core consists of hundreds of individually wrapped steel coils arranged in zones to provide targeted support where needed most. Each coil moves independently to isolate motion and conform to body contours. Reinforced foam encasement around the perimeter creates durable edge support that prevents roll-off and extends the usable sleep surface. The mattress measures 12.5 inches thick, providing substantial depth for proper support layering. The white and brown color scheme offers a clean, modern appearance suitable for various bedroom styles.

Construction quality emphasizes durability and safety throughout. All foams are CertiPUR-US certified, meaning they're made without harmful chemicals like formaldehyde, mercury, and certain phthalates. The mattress carries GREENGUARD Gold certification, indicating it meets strict standards for low volatile organic compound emissions. Notably, the construction is completely fiberglass-free, addressing common concerns about fiberglass particles in mattress covers. The bed-in-a-box packaging allows for compressed shipping and easy handling. Once unboxed, the mattress typically expands to its full dimensions within several hours. Maintenance involves regular rotation (every 3-6 months) to ensure even wear, though flipping isn't required due to the single-sided design. Spot cleaning with mild detergent and cold water is recommended for stains. The mattress works with most standard bed frames, foundations, and adjustable bases. The medium firmness level (6/10) provides enough give for pressure relief while maintaining sufficient support for proper spinal alignment. The hybrid design balances the contouring benefits of foam with the responsiveness and airflow of coils.

Performance

The Helix Midnight Mattress delivers balanced performance tailored to side sleepers and combination sleepers. The medium firmness level (6/10) provides enough cushioning to relieve pressure at shoulders and hips while maintaining sufficient support to prevent excessive sinkage. The SupremeSupport Memory Foam layer contours closely to body curves, reducing pressure points that can cause discomfort during side sleeping. This contouring happens gradually rather than instantly, allowing for proper spinal alignment as you settle into the mattress. The individually wrapped coil system responds dynamically to movement, providing push-back support that helps prevent the stuck feeling sometimes associated with all-foam mattresses. Motion isolation is particularly effective due to the pocketed coil design, which minimizes disturbance when a sleep partner moves or gets out of bed. Edge support remains firm thanks to the reinforced perimeter, making the entire sleep surface usable without significant roll-off near the edges. The hybrid construction promotes airflow through the coil channels, helping to regulate temperature throughout the night.

Temperature regulation benefits from multiple design elements working together. The GlacioTex cover provides immediate coolness upon contact and wicks away moisture to prevent heat buildup. Beneath the surface, the coil system allows air to circulate more freely than solid foam cores, dissipating body heat more effectively. The memory foam layer uses advanced formulations to resist heat retention common in traditional memory foam. While individual experiences with temperature regulation may vary based on room conditions and personal metabolism, the mattress incorporates several cooling technologies to address sleep overheating. Durability appears strong with the reinforced edges and quality materials, though long-term performance depends on proper care and rotation. The mattress maintains its shape well during compression and expansion cycles typical of bed-in-a-box products. Weight distribution feels even across the sleep surface, with no noticeable soft spots developing in testing periods. The balanced medium feel accommodates various sleeping positions while particularly benefiting side sleepers who need pressure relief at key contact points.
