I received a free Sparrow mattress from Nest Bedding. The Nest Sparrow mattress is a next-generation innerspring mattress. By that I mean it uses more modern technology to create a great sleep experience. The pocket coil construction helps to isolate motion but still provide some bounce. The memory foam helps to keep the mattress cool while still providing great pressure relief. The Sparrow is a great choice for people who are looking to either transition to a memory foam mattress or just want all the benefits of an innerspring with the benefits of foam as well.

Ordering the Sparrow Mattress

You can purchase the Sparrow direct from the Nest Bedding website.  It arrives in a box shipped by FedEx. Even though this mattress has springs, it can still be roll packed because of the pocket coils.  This is a heavy mattress. I ordered a full size and the UPS shipping weight was 75 lbs.  However because its in a box its definitely much easier to move into and around your house.

Unboxing the Sparrow Mattress

The Sparrow will come in a box like the one below with the Nest Bedding logo and all.

Here’s me unboxing the Sparrow. The mattress is very tightly wrapped so once you cut the plastic loose it almost pops open and is ready to sleep on in a few hours.


Specifications and Construction of the Sparrow

The Sparrow Signature Hybrid mattress is made to fit your sleep needs (right here in the USA).

  • Unzip the sides of this mattress to exchange the inner foam layer for a new one that’s more firm, softer, or if you just want to replace it (which extends the life of your mattress).
  • Does your partner like different types of mattress firmness than you? Order the Sparrow Signature Hybrid in King and Cal King sizes and get a different firmness on each side. Keep one side firm and the other plush, or mix a plush side with a medium…it’s your mattress (and your relationship), we want you to love it.
  • Individual coils isolate motion (so you won’t wake up when your partner reaches for a glass of water in the middle of the night).
  • Energex foam is responsive and offers a memory foam-like feel, without leaving a lasting imprint on the mattress.

The fire barrier is non-chemical hydrogenated silica.

Layer Details

1″ – Gel Memory Foam & Quilted THERMIC® phase change cover

Plush and cool, the quilted gel memory foam top gives you the added softness that doesn’t compromise the support underneath. THERMIC® is a patented temperature regulation technology that keeps the fabric from overheating. THERMIC® absorbs energy (heat) when the environment or body temperature goes up, stores this energy temporarily, and releases the energy as heat when the temperature cools down.

3″ – Blue Energex™ Temperature Responsive Foam

Energex™ provides a new, energetic alternative to conventional visco memory foam that retains all of the advantages of visco memory foam without slow recovery. Energex™ serves to bridge this gap between visco memory foam and latex foam. Its highly open, cool, and responsive polymer structure is designed to offer a superior alternative to latex or springs while providing outstanding pressure relief properties.

1″ – 3 lb. SmartFlow Support Foam

A minimal amount of this high density air flow foam is used to transition from the comfort layer, to the individually pocketed coils.

6″ – Reinforced Edge Coil Support Pocketed Coils

USA-made in our factory in Phoenix AZ; this individually wrapped coil system offers reinforced edge support and is warrantied at 20-years.

1″ – 3 lb. Base Support Foam

This foam support layer is purely structural. When pressure is applied to the coil system, this layer is there to act as a buffer between your foundation and the mattress.

So, what are pocket coils?
Here’s the definition from Wikipedia:
Marshall coils, also known as wrapped or encased coils or pocket springs, are thin-gauge, barrel-shaped, knotless coils individually encased in fabric pockets—normally a fabric from man-made, nonwoven fiber. Some manufacturers precompress these coils, which makes the mattress firmer and allows for motion separation between the sides of the bed. As the springs are not wired together, they work more or less independently: the weight on one spring does not affect its neighbours. More than half the consumers who participated in a survey had chosen to buy pocket spring mattresses
So as you can see, the Alexander Hybrid is leading the pack in terms of innovation.

 My Nest Sparrow Recommendation

The Nest Bedding Alexander Hybrid isn’t the only mattress that uses pocket coils however I have found that this mattress is really good at striking a balance with bounce and pressure relief.  Below is a video of me dropping a bowling ball on the mattress to illustrate motion transfer. This mattress isolates motion better than a Saatva


There is a zippered cover where you can swap out the top layer if you find it to be too firm or soft which can save a lot of hassle.  You’ll notice that the mattress has a tufted top where you will sink into the mattress a fair amount. It’s similar to a Saatva and softer than a WinkBed.

As for heat retention, this mattress cools quickly. Here’s an infrared video illustrating how fast it dissipates heat. I think this is due to a number of factors.


My Nest Sparrow Recommendation

It’s hard to go wrong with the Nest line of products. The Sparrow is a mattress that should please most sleepers. I found that you will sink into this mattress a little more than you would with the all-foam Alexander mattress. It has a little less bounce than the Aviya and WinkBed. I highly recommend this to side sleepers that prefer the feel of an innerspring but don’t want the motion transfer problems. This mattress also sleeps cool.

Nest Sparrow vs. Owl

Both models are popular, but they have distinct features and are designed for different types of sleepers. Here’s a comparison of the two:

Nest Sparrow (Alexander Signature Hybrid) Mattress:

  1. Construction: The Sparrow mattress is a hybrid that combines memory foam layers with pocketed coil support.
  2. Feel: Medium to luxury firm feel, offering a balance between contouring and support.
  3. Cooling: Features a thermic phase change cooling fabric which can help sleepers stay cool throughout the night.
  4. Best For: Sleepers who prefer the contouring feel of memory foam but also want the responsiveness and support of innerspring coils. It can cater to a broad range of sleeping positions.
  5. Other: It offers multiple firmness options to cater to different sleep preferences.

Nest Owl Latex Hybrid Mattress:

  1. Construction: The Owl mattress combines natural Dunlop latex with pocketed coil support.
  2. Feel: More responsive and bouncy due to the latex layer.
  3. Cooling: Latex tends to be more breathable than memory foam, so it can be a cooler sleeping surface.
  4. Best For: Those who prefer a more natural mattress material (latex is derived from rubber trees), or those who like a responsive, bouncy feel. It’s also suitable for those looking to avoid the “sinking in” sensation of memory foam.
  5. Other: It features organic cotton and wool in its construction, making it more eco-friendly.

Overall Comparison:

  • The Sparrow is more geared towards those who like the feel of memory foam, while the Owl offers the bounce and responsiveness of latex.
  • The Owl has a more eco-friendly and natural construction compared to the Sparrow.
  • Both mattresses offer good support due to their hybrid construction with pocketed coils.

Sparrow vs. Helix

The Nest Bedding Sparrow and Helix are both hybrid mattresses, meaning they combine foam and coil layers to create a supportive and comfortable sleeping surface. However, there are some key differences between the two mattresses.


The Nest Bedding Sparrow is made with a top layer of memory foam, followed by a layer of Energex foam, which is a responsive and supportive material. The bottom layer of the mattress is made of individually pocketed coils, which provide support and help to reduce motion transfer.

The Helix is also made with a top layer of memory foam, but the second layer is made of latex, which is a bouncy and resilient material. The bottom layer of the mattress is also made of individually pocketed coils.


The Nest Bedding Sparrow has a softer feel than the Helix. It is also more conforming, meaning that it will hug your body and provide pressure relief. The Helix has a firmer feel and is more responsive. It is also less conforming than the Sparrow.


The Nest Bedding Sparrow is generally less expensive than the Helix. However, the price of both mattresses will vary depending on the size you choose.

Trial and warranty

The Nest Bedding Sparrow comes with a 365-night trial period and a lifetime warranty. The Helix comes with a 100-night trial period and a 10-year warranty.

Which mattress is right for you?

The best mattress for you will depend on your individual preferences and sleep needs. If you prefer a softer and more conforming mattress, then the Nest Bedding Sparrow is a good option. If you prefer a firmer and more responsive mattress, then the Helix is a good option.

It is also important to consider your budget. The Nest Bedding Sparrow is generally less expensive than the Helix. However, the price of both mattresses will vary depending on the size you choose.
