In this comprehensive review, we will delve deep into the Nest Bedding Sparrow Mattress, formerly known as the Alexander Signature Hybrid. By the end of this article, you’ll have all the information you need to make an informed decision about this hybrid mattress .

A Brief Introduction to Nest Bedding

Established in 2011, Nest Bedding is a pioneer in the boxed mattress movement, which has transformed the way we approach sleep. They offer a diverse range of sleep products, including bed frames, foundations, nightstands, pet beds, sleepwear, pillows, sheets, blankets, toppers, and, of course, mattresses. With such a wide array of sleep-related products, Nest Bedding has become a one-stop-shop for all your bedroom needs.

The Sparrow Mattress – A Hybrid Marvel

Nest Bedding’s Sparrow Mattress, also known as the Alexander Signature Hybrid, is a true hybrid marvel. It combines the best of both worlds, with a blend of foam and coils that promise a luxurious night’s sleep. What sets this mattress apart is its availability in three firmness options: Plush, Medium, and Luxury Firm. This ensures that there’s a Sparrow mattress to suit the preferences of every sleeper.

Firmness Options

  • Plush (Soft – 3): Ideal for those who crave a cloud-like sleep experience.
  • Medium (Medium – 5): Strikes a balance between support and comfort, suitable for most sleepers.
  • Luxury Firm (Firm – 7): Offers robust support for those who prefer a firmer mattress.

The Anatomy of the Sparrow

Let’s take a closer look at the construction of the Nest Bedding Sparrow Mattress. Understanding what goes into your mattress is crucial to choosing the right one for your needs.

Cover Material

The Sparrow features a cover made with Thermic Phase Change fabric. This material actively regulates the mattress’s surface temperature, ensuring a cool and comfortable night’s sleep. Additionally, a 1-inch layer of 4 pounds per cubic foot (PCF) memory foam is quilted into the cover, providing a plush and cushioned feel.

Comfort Layer

The comfort layer consists of 3 inches of 2.8 PCF Energex foam. This proprietary polyfoam offers supportive contouring and quickly responds to changes in position. Its high density contributes to durability and excellent pressure relief.

Transition Layer

A 1-inch layer of polyfoam with a density of 3 PCF acts as the transition layer. It separates the softer comfort system from the firmer core, ensuring a smooth transition between layers.

Support Core

The Sparrow’s support core consists of 16-gauge Quantum Edge pocketed coils. These coils move independently, limiting motion transfer and adding bounce to the mattress. They also promote airflow, helping to regulate temperature. The base of the mattress is a 1-inch layer of polyfoam, providing essential foundational support.

Performance Tests: Assessing Excellence

Cooling Test

A well-regarded aspect of the Nest Bedding Sparrow mattress is its exceptional cooling capabilities. In rigorous cooling tests, the mattress consistently outperforms competitors, maintaining a comfortable temperature throughout the night. With a maximum surface temperature of 90.6°F (compared to the industry average of 90.9°F), the Sparrow keeps you cool, promoting restful sleep.

Sinkage Test

The Nest Bedding Sparrow showcases moderate sinkage, measuring at 2.70″. While slightly deeper than the industry average of 2.22″, this sinkage doesn’t translate to the classic memory foam “stuck” feeling. Instead, the Sparrow offers a more generalized contour, ensuring pressure relief without the sensation of being trapped.

Motion Transfer Test

Motion transfer is an important consideration for couples sharing a bed. The Sparrow performs admirably in this regard, with a total acceleration range of 7.12 m/s². Although higher than the average of 5.77 m/s², it’s important to note that the Sparrow’s responsive foams and pocketed coil base contribute to this result. While it may not be ideal for the most motion-sensitive sleepers, it remains a solid choice for most.

Response Time

When it comes to responsiveness, the Nest Bedding Sparrow mattress impresses. Within 0.3 seconds, most of the materials recover to their original shape, ensuring a supportive and comfortable sleep surface. Even the full recovery at 0.6 seconds is faster than the industry average, promising a responsive and adaptive sleeping experience.

Bounce Test

With a bounce height of 10.64″, the Sparrow offers a level of bounce that strikes a perfect balance. It’s easy to move around on the mattress, making it a convenient choice for active sleepers. Moreover, it provides excellent support for intimacy without feeling excessively bouncy.

Edge Support Test

The Sparrow excels in edge support when sitting, offering a sinkage depth of 4.0″. This level of support remains consistent even when direct pressure is applied to the edge, ensuring a stable seating experience. However, while lying directly on the edge, the support is good but not outstanding, as the quilted cover and top-layer foams compress slightly. Still, it’s noteworthy that this performance is on par with or better than many competitors.

Sex Test

For couples seeking an engaging sleep experience, the Sparrow doesn’t disappoint. With a sex score of 9.9, it ranks high in this category. It combines a perfect bounce score with excellent edge support, minimal noise, and superb pressure relief. All these factors contribute to an optimal environment for intimate moments.

Pressure Relief Test

Pressure relief is where the Nest Bedding Sparrow truly shines. Its quilted covers, in combination with high-grade foams and pocketed coils, provide exceptional pressure relief. Sleepers of all sizes can enjoy a comfortable and soft surface that remains supportive, responsive, and cool. The Sparrow excels in delivering a harmonious balance of comfort and pressure relief.

Off-Gassing Test

Upon unboxing, there is a moderate smell associated with the Sparrow mattress, which lingers for approximately two days. This is in line with the industry average of 2.57 days for off-gassing. Beyond this initial period, the Sparrow remains virtually odor-free, allowing you to enjoy your sleep without any lingering unpleasant smells.

Tailoring to Different Sleeping Styles and Body Weights

Your sleeping style and body weight play a significant role in determining which firmness option of the Sparrow Mattress is best for you. Let’s break it down:

Side Sleepers

  • Under 130 lbs: Plush or Medium options provide the ideal balance of pressure relief and support.
  • 130-230 lbs: The Medium option strikes the right balance of pressure relief and support.
  • Above 230 lbs: Luxury Firm is recommended for superior pressure relief and support.

Back Sleepers

  • Under 130 lbs: Plush or Medium options offer excellent support and contouring.
  • 130-230 lbs: The Medium option provides even support.
  • Above 230 lbs: Luxury Firm ensures even support without excessive sinkage.

Stomach Sleepers

  • Under 130 lbs: Medium provides even support with gentle cushioning.
  • 130-230 lbs: Luxury Firm balances support and contouring.
  • Above 230 lbs: Luxury Firm offers exceptional support and even weight distribution.


Sharing a bed with a partner can sometimes lead to sleep disturbances caused by motion transfer. However, the Nest Sparrow’s exceptional motion isolation means you won’t feel your partner’s movements. Say goodbye to those restless nights.

Customization Options

Firmness Tailored to You

The Nest Bedding Sparrow offers the option to customize the firmness of your mattress. You can exchange or replace the top layer of foam to achieve your desired level of firmness. This feature ensures that your mattress remains tailored to your comfort preferences throughout its life.

Split Firmnesses

For those sharing a mattress with a partner, the King or Cal King sizes allow for split firmness levels on each side. This customization caters to the unique sleep needs of both individuals, ensuring a harmonious night’s rest.
