Amerisleep AS5 vs Helix Sunset Luxe: Which Soft Mattress Fits You?
What we checked: Queen price, trial length, return fees, the sag threshold, and slat spacing.
Quick answer: I’d pick the Amerisleep AS5 if you want a very soft all-foam mattress, a 100-night trial, and a 20-year warranty. Choose Helix Sunset Luxe if you want a soft hybrid with a pillow top, zoned support, an optional GlacioTex cover, and a longer 120-night trial.
The choice comes down to response: AS5 is foam from top to bottom; Sunset Luxe pairs plush cushioning with pocketed coils.
How we compared: I compared the Amerisleep AS5 and Helix Sunset Luxe using their official product pages, trial policies and warranty documents. We did not sleep on these two models for this article and did not measure firmness, surface temperature, motion transfer or edge support. Sleep-position advice follows the firmness each brand advertises; prices and promotions change, so the cart total is the one that counts.

How do the AS5 and Sunset Luxe compare?
| What matters | Amerisleep AS5 (all foam) | Helix Sunset Luxe |
|---|---|---|
| Overall pick | Our pick for all-foam comfort and a lower listed Queen price | Better fit if you specifically want a soft hybrid; Helix advertises a Limited Lifetime Warranty |
| Feel and height | Soft; 14 inches | Soft feel; Luxe product listings describe a 13.5-inch profile |
| Support system | Foam comfort layers over a supportive foam base | Plush foam comfort over pocketed coils; zoned lumbar support is a Luxe feature |
| Cooling choice | Amerisleep promotes Bio-Pur and Refresh Cooling Technology | TENCEL cover or optional GlacioTex Cooling Cover |
| Trial | 100 nights | 120 nights |
| Warranty | Amerisleep states a 20-year warranty | Helix advertises a Limited Lifetime Warranty; review the applicable terms and exclusions |
| Best starting point | Side and combination sleepers who want a deep foam hug | Side sleepers wanting plush cushioning with a coil core |
- AS5 advantages: all-foam contouring, a slightly lower displayed Queen offer, and clearly stated warranty coverage and base requirements.
- AS5 trade-offs: only 100 trial nights and a soft feel that may not suit shoppers who want a firmer, springier bed.
- Sunset Luxe advantages: a pillow-top hybrid, choice of cooling cover, and 20 extra trial nights.
- Sunset Luxe trade-offs: its displayed Queen price is slightly higher, and its plush coil feel differs from the AS5’s all-foam contour.
Amerisleep sells the AS5 all-foam and AS5 Hybrid as separate models. Helix offers the Sunset Luxe with a TENCEL cover or optional GlacioTex upgrade; compare the same cover configuration.
What is inside each mattress?
Amerisleep AS5: foam from top to bottom
Amerisleep describes the AS5 as its softest mattress and lists it at 14 inches tall. The all-foam version uses Bio-Pur memory foam, Active Flex foam and a supportive base. Amerisleep says Bio-Pur is plant-based and designed for cooling comfort, while Active Flex is intended to add support and responsiveness beneath the plush surface. Your temperature and pressure-relief experience will depend on your body, bedding and room conditions.
Foam contours closely rather than producing the lifted feel of coils. If you want cushioning around your shoulders and hips, the AS5 is the all-foam option; if you prefer a buoyant hybrid feel, consider the Sunset Luxe.
Helix Sunset Luxe: soft comfort over coils
The Sunset Luxe combines plush comfort materials with pocketed coils. Helix describes the Luxe upgrade as adding zoned lumbar support and a premium quilted pillow top. It is still a soft model; “zoned” does not turn it into a firm mattress. Instead, the design gives the bed a different support structure from the all-foam AS5 while retaining a cushioned top feel.
The Sunset Luxe is offered with a TENCEL cover or an optional GlacioTex Cooling Cover. The latter is a paid upgrade and Helix describes the fabric as cool to the touch. Check which cover is selected when you review the price; do not compare a base-cover price with an upgraded configuration as if they were the same bundle.
The Sunset Luxe is listed at 13.5 inches and the AS5 at 14 inches; account for that height when choosing fitted sheets.
Which one feels better for your sleep position?
Side sleepers: Either can make sense if you want a soft surface. Amerisleep says the AS5 is designed for side and combination sleepers; Helix positions the Sunset Luxe for side sleepers who prefer a soft feel. The AS5 gives you a closer foam contour, while the Helix combines cushioning with a coil core. If you want your shoulder and hip to sink into foam, start with AS5. If you want a plush top but would rather have coils under it, start with Sunset Luxe.
Back sleepers: Be cautious about choosing either one solely from a label. Both are soft, and the right feel depends on your build, preferred support and how much sinkage feels comfortable. A back sleeper who likes a cushioned surface can consider the AS5; someone who prefers the more buoyant feel of a hybrid may favor Helix. If you usually need a firmer mattress, compare firmer models instead of assuming that the Luxe zoning will make the Sunset feel firm.
Stomach sleepers: These are not our first choices if you want a firm, level surface. The soft feel can allow more sinkage than some stomach sleepers prefer. If you sleep mostly on your stomach, look at a firmer option and use the home trial only after reading its exact terms.
Combination sleepers: Amerisleep specifically includes combination sleepers among the AS5’s intended shoppers, and its Active Flex layer is described as responsive. Helix’s coil core may appeal if you want a more springy hybrid response. Neither description replaces trying the mattress: how easily you move can vary with your body and sleeping habits.
Cooling, motion and edge support
Cooling: Amerisleep promotes Bio-Pur and Refresh Cooling Technology; Helix offers an optional cool-to-the-touch GlacioTex cover. Surface temperature was not measured.
Motion and edges: AS5 uses an all-foam support system, while Sunset Luxe has pocketed coils and a coil perimeter; motion transfer and edge support were not measured.
What is the Queen price for each mattress?
The Queen offers below compare the base configurations; the optional GlacioTex cover can change the Helix total.
| Size | Amerisleep AS5 all-foam sale price | Helix Sunset Luxe price |
|---|---|---|
| Queen | $1,849 sale ($2,349 list) | $1,874 displayed ($2,498.66 list); cover selection may affect total |
The displayed Queen offers differ by $25, with the AS5 lower.
What does a trial actually cost if you return it?
| Trial term | Amerisleep AS5 | Helix Sunset Luxe |
|---|---|---|
| Trial period | 100 nights | 120 nights |
| Minimum before return | 30 nights | 30 nights |
| Return fee | $0 (free returns) | $0 (no return fee) |
| Trials per household | Not stated in the trial policy | Not stated in the published policy |

Who should buy the Amerisleep AS5?
- Choose the AS5 if a soft, close-contouring all-foam feel is what you want.
- It is a stronger fit if you want a clearly stated 100-night trial and a 20-year warranty from the mattress maker.
- Consider it if you sleep on your side or change positions and like a cushioned surface.
- Do not buy the AS5 if you want firm, springy support or sleep mainly on your stomach and want less sinkage.
Who should choose the Helix Sunset Luxe?
- Choose the Sunset Luxe if you want a soft hybrid rather than an all-foam mattress.
- It is a good candidate if a pillow top, pocketed coils and zoned lumbar support match the feel you are seeking.
- Consider the GlacioTex cover if you want Helix’s optional cool-to-the-touch cover and are comfortable checking its added price.
- Do not buy Sunset Luxe if you want a firm, low-sinkage feel or an all-foam mattress.
Also considered
- Amerisleep AS3: a medium-feel all-foam alternative if the AS5’s extra softness is too much.
- Amerisleep AS5 Hybrid: for shoppers who want the AS5 model’s plush profile with coils; it is a different mattress from the all-foam version in this comparison.
- Helix Moonlight Luxe: another soft Helix Luxe option to compare if you want to stay with Helix’s plush hybrid category.
Frequently asked questions
Is the Amerisleep AS5 softer than the Helix Sunset Luxe?
Amerisleep calls the AS5 soft and its softest model; Helix lists the Sunset Luxe with a soft feel. Both are plush options, but they feel different because the AS5 is all foam and the Helix is a hybrid. Firmness labels are not a direct, standardized measurement across brands.
Which is better for side sleepers?
Based on their advertised soft feels, either may suit a side sleeper seeking plush cushioning. Choose AS5 for close foam contouring or Sunset Luxe for a coil-supported hybrid feel.
Does the Helix Sunset Luxe have a cooling cover?
Helix offers a standard TENCEL cover and an optional GlacioTex Cooling Cover on the Sunset Luxe. Confirm which cover is selected and how it changes your cart total.
Which mattress has the longer trial?
Helix offers 120 nights, with a 30-night minimum before return; Amerisleep offers 100 nights, also with a 30-night minimum. Both advertise free trial returns.

Amerisleep states a 20-year warranty for the AS5. Helix advertises a Limited Lifetime Warranty for the Sunset Luxe. Each warranty has its own coverage terms, exclusions and claim requirements.
