The Helix Plus is a foam-and-coil hybrid made with higher-weight sleepers in mind. This review began with Ben’s hands-on experience with the earlier Helix Nightfall/Plus model; the current mattress has since changed. The original observations and photos below describe that earlier bed, while current specifications and policies are identified separately.

Our verdict
The Helix Plus is worth considering if you want a supportive hybrid and a more cushioned feel than some very firm mattresses marketed to heavier sleepers. When I reviewed the earlier model, I found it softer than the Big Fig and WinkBed Plus models I had tried. Comfort is individual, and that comparison applies to the versions I tested, not necessarily today’s redesigned beds.
Ben’s findings on the original model
I weighed about 200 pounds when I tested it, so my experience will not represent every plus-size sleeper. Compared with the Big Fig and WinkBed Plus models I reviewed at the time, the Helix felt softer and more accommodating. The 14-pound bowling-ball photos below show how the original surface compressed, including near the edge; they are illustrations, not standardized measurements of today’s mattress.
I observed some motion transfer in the original hybrid. Its individually wrapped coils moved independently, which I expected to reduce motion compared with a traditional connected-coil system. If you share a bed and are easily disturbed, a trial at home is a useful way to judge whether movement is noticeable to you.
What is the current Helix Plus made of?
Helix currently describes the Plus as a medium-firm hybrid with a knit cover, memory and responsive foam layers, and individually wrapped coils. The brand offers optional upgrades, including a cooling pillow top and an additional support layer; selected options change the price and feel. Its current listing describes the standard queen as approximately 11.5 inches high. Check the current Helix product page for the configuration you are ordering.
The layer diagram and cover photographs in the gallery are from the earlier Nightfall, not a specification sheet for today’s model. Do not assume the old cover is removable or washable on a new purchase; follow the care instructions for the model delivered.
Who should consider it?
- Higher-weight sleepers: Helix states that the Plus line is designed for up to 1,000 pounds combined, or 500 pounds per sleeper. Use a suitably supportive foundation as well.
- Side sleepers: Look for enough shoulder and hip cushioning. A medium-firm feel can work for some, but body weight and pressure sensitivity matter.
- Back and stomach sleepers: Pay attention to whether the hips stay supported without excessive sink. Those wanting a very firm surface should compare other options.
- Couples: Consider edge space, mattress width and motion transfer together; each partner’s comfort preferences count.
Price, trial and warranty
Prices depend on size, upgrades and promotions. Compare the actual checkout price and any delivery or setup charges rather than relying on the old price in this review.
Helix currently advertises a 365-night trial for qualifying direct mattress purchases. The limited lifetime warranty for eligible mattresses purchased after February 1, 2025 covers specified defects, with prorated replacement costs after the first 10 years. Earlier purchases follow the warranty in force when bought. Check eligibility, support requirements and the complete terms before buying.
Retailer return and delivery policies may differ from Helix-direct terms. Ask the seller for the terms that apply to your order. For showroom availability, contact Yawnder’s Encinitas showroom before visiting.

Frequently asked questions
Is the Helix Plus firm?
Helix describes the current model as medium-firm. How firm it feels depends on body weight, position and the options chosen.
What is its weight capacity?
Helix lists up to 1,000 pounds combined, or 500 pounds per sleeper, for the Plus line. Confirm that your frame and foundation can support the mattress and everyone using it. See Helix’s weight guidance.
Does a cooling cover make the mattress cold all night?
A cooling cover may feel cool to the touch; room temperature, bedding and individual sensitivity also affect how warm you sleep. Compare the standard and upgraded covers before paying extra.
Is this the same mattress as the original Nightfall?
The Plus line grew out of the earlier Nightfall review, but materials and configurations have changed. Treat the original test observations as historical and verify today’s construction with the seller.

What’s inside the Helix Plus
Layer-by-layer construction as published by the manufacturer, listed from the sleep surface down. Foam density describes how much material is in a layer (a durability signal); IFD/ILD describes how soft or firm that foam feels. Density is never used as a feel measurement. Current generation: Current Helix redesign (2025). Specs verified against the manufacturer’s published construction on September 10, 2026.
