Finding a mattress that offers proper support and comfort for heavier individuals can be a challenge. Many standard mattresses lack the durability and firmness needed to maintain spinal alignment and resist sagging over time. That’s where the Helix Plus comes in—a hybrid mattress specifically engineered for plus-size sleepers. Designed with reinforced coils, dense foams, and a medium-firm feel, the Helix Plus aims to deliver long-lasting comfort without compromise.
In this comprehensive 2025 review, we’ll explore the Helix Plus’s construction, performance across key categories, pricing, expert and user feedback, and how it compares to other Helix models. Whether you’re a back sleeper, stomach sleeper, or combination sleeper with a larger frame, the Helix Plus might be your ideal match.
Construction and Materials
The Helix Plus is a hybrid mattress built to handle higher weight capacities while maintaining comfort and support. Here’s a breakdown of its layers:
Base Layer
A layer of high-density polyfoam stabilizes the mattress and supports the coil system.
This robust construction ensures the mattress remains supportive and durable, even under higher pressure.
Cover
The standard cover is a breathable knit fabric that feels soft and cool. For hot sleepers, Helix offers an upgrade to the GlacioTex Cooling Cover, which uses phase-change materials to regulate temperature.
Comfort Layer
At the top lies Helix’s Ultra-Dense Memory Plus Foam, designed to provide pressure relief without excessive sinkage. It’s firmer than the foam used in other Helix models, making it ideal for heavier individuals.
Transition Layer
Next is Helix Dynamic Foam, a latex-like material that adds bounce and responsiveness. This layer helps prevent the “stuck” feeling and makes movement easier.
Support Layer
The core features extra-tall, individually wrapped coils that are reinforced to support heavier weights. These coils are zoned for targeted support and enhanced edge stability.
Firmness and Feel
Helix rates the Plus as a medium-firm mattress, and most testers place it around a 7 out of 10 on the firmness scale. It offers a balanced feel—firm enough to support heavier bodies, yet cushioned enough to relieve pressure.
Back Sleeper – The Plus excels for back sleepers, especially those over 250 lbs. The dense foam and reinforced coils support the lumbar region and maintain spinal alignment.
Stomach Sleepers – Stomach sleepers benefit from the firm surface, which keeps the hips elevated and prevents lower back strain.
Side Sleepers – While the Plus offers decent pressure relief, some lighter side sleepers may find it too firm. Heavier side sleepers, however, will appreciate the support and contouring.
Combination Sleepers – The responsive foam and coil system makes it easy to switch positions. The Plus is a great choice for heavier combination sleepers who need bounce and support.
Cooling and Temperature Regulation
The Helix Plus performs well in temperature regulation, thanks to its breathable design and optional cooling upgrades.
- Breathable Coil Base: Promotes airflow and prevents heat buildup.
- Optional Cooling Cover: The GlacioTex upgrade actively cools the surface.
In testing, the Plus maintained a neutral temperature throughout the night. With the cooling cover, it’s a solid choice for hot sleepers.
Motion Isolation and Edge Support
Motion Isolation
Despite its coil base, the Plus offers solid motion isolation. The dense foam layers absorb movement, making it suitable for couples.
Edge Support
Reinforced coils around the perimeter provide excellent edge support. You can sit or sleep near the edge without feeling unstable—an important feature for heavier sleepers.
Durability and Longevity
The Helix Plus is built to last. With high-quality materials and a reinforced coil system, it’s expected to maintain its shape and support for 8–10 years. The 15-year warranty adds peace of mind.
Users report minimal sagging and consistent performance over time. The edge support and firmness remain strong even after years of use.
