The company backs the mattress with a 120-night sleep trial and lifetime warranty, allowing buyers to test it risk-free.
Product Overview
The Helix Midnight mattress features a five-layer hybrid construction with a breathable knit cover pillow top for airflow. Its medium feel ranks 6 out of 10 on the firmness scale, where 10 is the firmest. The mattress uses premium pressure-relieving foams that contour to hips and shoulders. An exclusive SupremeSupport 2.5 Memory Foam layer provides 2.5 times more cushioning than standard memory foam. Hundreds of individually wrapped steel coils and reinforced side perimeters help cradle sleepers and limit motion transfer between partners. The mattress is compressed, rolled, and shipped in a box for convenient delivery. It comes in various sizes including Twin XL, which measures 80 inches long by 38 inches wide by 11.5 inches thick. The materials are fiberglass-free, GREENGUARD Gold certified for low chemical emissions, and made with CertiPUR-US certified foams.

Design & Build
The Helix Midnight mattress features a five-layer hybrid construction designed for durability and comfort. The top layer consists of a Breathe Knit cover pillow top that promotes airflow while providing a soft surface. Beneath this, premium pressure-relieving foams contour to the body's curves, with an exclusive SupremeSupport 2.5 Memory Foam layer offering enhanced cushioning. The core support system includes hundreds of individually wrapped steel coils that respond independently to pressure points. Reinforced side perimeters around the coil system provide edge support and prevent premature sagging. The mattress measures 11.5 inches thick in the Twin XL size, with dimensions of 80 inches long by 38 inches wide. The white and brown color scheme creates a neutral aesthetic that blends with various bedroom decors.
All materials are carefully selected for safety and performance. The mattress is completely fiberglass-free, addressing common concerns about fiber shedding in some mattresses. It carries GREENGUARD Gold certification, indicating it meets strict standards for low chemical emissions. The foams are CertiPUR-US certified for content, durability, and environmental stewardship. Each mattress is assembled in Helix's own Arizona facility rather than outsourced overseas. The bed-in-a-box packaging compresses the mattress for shipping, then allows it to expand to full size when unpacked. The construction balances plush comfort layers with supportive coils to create a medium feel that works well for most sleep positions.
Performance
The Helix Midnight mattress performs well for its target audience of side sleepers and combination sleepers. The medium firmness rating of 6 out of 10 provides enough cushioning for pressure relief at hips and shoulders while maintaining adequate support for spinal alignment. The individually wrapped coils respond independently to body weight and movement, reducing motion transfer between sleeping partners. This makes the mattress suitable for couples where one person moves frequently during sleep. The reinforced edge support maintains mattress integrity along the sides, preventing the feeling of rolling off when sleeping near the edge. The breathable knit cover and airflow-promoting design help regulate temperature throughout the night.
The hybrid construction combines the contouring benefits of memory foam with the responsiveness of coil systems. Sleepers experience minimal sinkage while still receiving pressure relief at key contact points. The mattress adapts well to various sleeping positions, though it's specifically optimized for side sleeping. The bed-in-a-box delivery system allows easy setup in any room without professional assistance. Once unpacked, the mattress expands to its full dimensions within hours. The quality materials and construction contribute to long-term durability, though individual experiences with firmness and comfort may vary based on body weight and personal preferences.
