How did the Stearns and Foster Lux Hybrid Firm Mattress perform?

Performance Score: 8.4/10

1. How is back alignment and overall support? (Score: 8/10)

The Lux Hybrid Firm mattress excels in providing back alignment and overall support, particularly for side sleepers. Many users reported significant relief from back pain, attributing this to the mattress’s firm support combined with its contouring memory foam layer. One user mentioned, “It provided excellent support for my back, aligning my spine perfectly,” while another noted, “Really good for my lower back issues, but my partner didn’t find it as supportive.” The mix of innerspring coils and memory foam ensures that the mattress doesn’t sink too much, offering a stable surface for those needing extra back support.

2. How is the firmness and pressure relief? (Score: 9.8 /10)

The firmness of this mattress received mixed reviews. While it is designed to be firm, many users found it softened to a comfortable level after some use. One user stated, “The mattress is quite firm, but it softened up nicely with use,” highlighting its initial firmness. However, some users felt it lacked adequate pressure relief, especially if they were expecting a softer surface. “I expected more pressure relief; it’s a bit too firm for me,” mentioned another reviewer, pointing out that it may not be the best option for those seeking a plush feel.

3. How is it for partners, kids or pets? (Score: 9.8/10)

Compatibility with different sleeping positions is a notable aspect, with side sleepers finding the most comfort due to the contouring nature of the memory foam. “Great for side sleeping, but not ideal for stomach sleepers,” said one reviewer, reflecting a common sentiment. Back sleepers generally found it suitable, with one noting, “I’m a back sleeper, and it worked fine for me, but my stomach-sleeping husband didn’t like it.” The mattress seems less favorable for stomach sleepers, who might find the sinking feeling uncomfortable.

4. How is the edge support? (Score: 8.5/10)

Edge support is a strong suit of the Lux Hybrid Firm mattress, thanks to its reinforced side rail system. Users frequently praised its stability, with comments like, “Very sturdy edges, no sagging when I sit on the side.” This feature is particularly beneficial for those who often sit or sleep near the edge of the bed. Another user mentioned, “Good edge support, much better than my old mattress,” indicating that the mattress performs well compared to others in the same category.

5. How is the cooling? (Score: 7.5/10)

The cooling aspect of this mattress received mixed reviews. While the luxurious Tencel cooling cover helps to some extent, the memory foam layer tends to retain heat. One user noted, “Feels a bit warm at times, especially during summer,” highlighting the mattress’s potential to sleep hot. Another mentioned, “The cooling cover helps, but it’s still a bit hot for my liking,” suggesting that while there are cooling features, they may not be sufficient for those who are particularly heat-sensitive.

6. Eco-friendly? How is the off-gassing? (Score: 6.9/10)

Environmental friendliness and off-gassing are areas where the Lux Hybrid Firm mattress could improve. Some users reported initial off-gassing odors, though they dissipated quickly. One user said, “I noticed a bit of off-gassing initially, but it went away quickly.” There is also a lack of information about the use of eco-friendly materials, which was a concern for some environmentally conscious buyers. “Would prefer more eco-friendly materials, not sure about the environmental impact,” expressed a reviewer, pointing out the need for more transparency regarding materials and manufacturing practices.

7. Does it have good motion isolation? (Score: 9.9/10)

Motion isolation is a standout feature of the Lux Hybrid Firm mattress. Users consistently praised its ability to minimize disturbances from a partner’s movements. One user commented, “Barely feel my partner moving, excellent for light sleepers,” underscoring its effectiveness. Another reviewer said, “Great for reducing motion transfer, no disturbances at night,” making it a top choice for couples, particularly those with different sleep schedules or restless partners.

8. Warranty (Score: 7.5/10)

The warranty offered by Stearns and Foster is standard, but it has room for improvement. It covers a period of 10 years, which is typical in the industry, but the conditions for triggering the warranty—such as a 1.5-inch sag—are viewed as less favorable. One user noted, “Standard 10-year warranty, but wish it covered more issues,” reflecting a common desire for more comprehensive coverage. Another said, “Warranty is okay, but sagging threshold could be better,” indicating that the terms might not be sufficient for long-term peace of mind.

9. Sleep Trial (Score: 7.9/10)

The sleep trial period is seen as reasonable, but the associated return fee detracts from its appeal. Stearns and Foster offers a 30 to 90-day trial, which gives users time to decide if the mattress meets their needs. However, a user mentioned, “The return fee is a bit of a turn-off, but the trial period is decent,” pointing out the cost of returning the mattress if it doesn’t work out. Another reviewer stated, “Not the best sleep trial, but 30-90 days is enough to decide,” indicating that while the trial period is adequate, the potential return costs could be a deterrent.

10. Customer and Trusted Ratings (Score: 8/10)

Customer reviews and ratings from trusted sources are varied, leading to an overall mixed perception. Many customers expressed satisfaction with their purchase, citing comfort and support as key benefits. One user said, “Mixed reviews overall, some love it, others not so much,” reflecting the divergent opinions. Another noted, “Customer service was helpful, but opinions on the mattress are varied,” indicating that while customer support is responsive, the mattress itself garners a range of reactions. This variability suggests that individual preferences and experiences play a significant role in overall satisfaction.



A Closer Look at the Stearns & Foster Mattress Materials

Top Layer – Tencel™ Cover

The mattress features a luxurious Tencel™ cover, known for its softness and moisture-wicking properties. Tencel™ is derived from sustainable wood sources and helps to maintain a cool and dry sleeping environment by reducing heat buildup.

Comfort Layer – TEMPUR-ES® Memory Foam

Directly beneath the Tencel™ cover is a layer of TEMPUR-ES® memory foam. This material is renowned for its conforming abilities, providing personalized comfort by contouring to the body’s shape. It offers pressure relief, especially for the shoulders and hips, making it a great choice for side sleepers.

Support Layer – IntelliCoil® Micro HD Layer

Below the memory foam, there is the IntelliCoil® Micro HD layer, consisting of hundreds of individually wrapped coils. These coils are designed to provide adaptive support and enhance the overall comfort of the mattress. They offer targeted support to different parts of the body, ensuring proper spinal alignment and reducing pressure points.

Transitional Layer – Gel Memory Foam

This layer provides a transition between the softer comfort layers and the firmer support layers below. Gel-infused memory foam helps to enhance cooling by dissipating heat and also adds an extra layer of conforming support.

Support Core – IntelliCoil® HD System

The core of the mattress features the IntelliCoil® HD system, a series of high-density coils encased in fabric pockets. These coils offer robust support, reduce motion transfer, and provide a stable base for the mattress. This system is crucial for maintaining the mattress’s shape and durability over time.

Edge Support – PrecisionEdge™ System

The edges of the mattress are reinforced with the PrecisionEdge™ system. This technology enhances edge support, preventing sagging and ensuring that the mattress remains supportive right to the edges. It also increases the usable sleeping surface area, making the mattress feel larger.

Base Layer – High-Density Foam

The bottom layer consists of high-density foam that serves as a durable foundation for the entire mattress structure. This layer adds longevity to the mattress and ensures that it maintains its shape and support over years of use.



Here is a list of the pros and cons of the Stearns and Foster Lux Hybrid Firm mattress based on user reviews:


  • Back Support: Users consistently praise the mattress for providing excellent spinal alignment and relief from back pain, making it a great choice for those with chronic back issues.
  • Motion Isolation: The mattress excels in minimizing motion transfer, ensuring that movements from a sleeping partner do not disturb your rest, which is particularly beneficial for couples.
  • Edge Support: The reinforced edges offer sturdy support, preventing sagging and making the mattress ideal for sitting or sleeping near the edge without feeling like you might roll off.
  • Comfort: The memory foam surface contours to the body over time, offering a plush yet supportive feel that adapts to your sleeping posture, enhancing overall comfort.
  • Luxury Feel: High-end materials and thoughtful construction provide a premium sleeping experience, making this mattress feel luxurious and well-crafted.


  • Heat Retention: Despite the cooling cover, some users find the mattress retains heat, making it less suitable for hot sleepers who may feel uncomfortable during warmer nights.
  • Stomach Sleepers: The contouring nature of the memory foam may cause an unwanted sinking feeling for stomach sleepers, leading to discomfort and improper spinal alignment.
  • Return Fee: There is a potentially costly return fee if the mattress is returned during the trial period, which can deter customers who are not completely sure about their purchase.
  • Environmental Concerns: The lack of information on eco-friendly materials and sustainable practices raises concerns for environmentally conscious buyers looking for a greener option.
  • High Price Tag: The mattress falls into a higher price range, which may not fit all budgets, making it less accessible for those looking for a more affordable option.


Our Analysis

The Stearns and Foster Lux Hybrid Firm mattress combines traditional innerspring technology with modern Tempur-Pedic memory foam to provide a unique sleeping experience. It is designed to offer excellent back support and motion isolation, making it a standout choice for those with back pain and couples. The sturdy edge support and overall luxurious feel add to its appeal, although the mattress may retain heat and may not be ideal for stomach sleepers. The higher price point and potential return fee during the trial period are considerations for prospective buyers.

Customer Insights
Customer reviews reflect a mix of high praise and some critical feedback. Many users commend the mattress for its superior back support and spinal alignment, with side sleepers particularly appreciating the contouring comfort for hips and shoulders. Motion isolation receives high marks, with users noting minimal disturbance from partner movements. The edge support is frequently highlighted as a positive feature, providing stability and preventing sagging.

Some users express concerns about the mattress retaining heat, which can be a drawback for hot sleepers. The firmness is generally well-received, although it may feel too firm initially for some, and the sinking sensation is not suitable for stomach sleepers. There are environmental concerns due to the lack of eco-friendly material information, and some users find the return fee during the trial period to be a significant drawback.

The Final Verdict: 8.4/10

The Stearns and Foster Lux Hybrid Firm mattress is a high-end option that delivers on its promise of comfort and support, particularly for side and back sleepers. Its luxurious feel, combined with excellent motion isolation and sturdy edge support, makes it a worthy investment for those seeking a premium sleeping experience. However, it may not be the best choice for stomach sleepers or those who sleep hot.

Additionally, environmentally conscious buyers might find the lack of transparency regarding materials a concern, and budget-conscious shoppers might be deterred by the higher price and return fee. Overall, if you prioritize support, motion isolation, and a luxurious feel, and can accommodate its price point, the Stearns and Foster Lux Hybrid Firm mattress is a solid choice.

Stearns and Foster Warranty

The Stearns and Foster Lux Hybrid Firm mattress comes with a 10-year limited warranty, providing standard coverage within the industry. This warranty covers defects in materials and workmanship, ensuring that the mattress meets the company’s quality standards. For the warranty to be applicable, the mattress must exhibit sagging or body impressions greater than 1.5 inches. If significant sagging within this threshold occurs during the warranty period, the mattress may be eligible for repair or replacement.

This warranty reflects Stearns and Foster’s confidence in the durability and longevity of their product. However, some users feel the sagging threshold could be more accommodating, and additional coverage for various issues would enhance peace of mind. Despite these concerns, the warranty ensures that your investment is protected against major manufacturing defects for a decade.

Stearns and Foster also offers a 30 to 90-day sleep trial, allowing you to test the mattress at home. This trial period gives you sufficient time to determine if the mattress suits your sleep needs. However, it is important to note that returns within this period may incur a return fee of up to $175, which can be a drawback for some customers. Nonetheless, this trial period, combined with the warranty, underscores Stearns and Foster’s commitment to customer satisfaction and product quality.
