What's Inside The Nest Bedding Sparrow

In a nutshell:

  • 1″ gel memory foam quilted mattress cover
  • 3″ Energex™ Temperature Responsive Foam
  • Transition foam layers
  • 6″ of pocketed coils

In more detail...

1″ Gel Memory Foam Quilted Mattress Cover

The Nest Bedding Sparrow’s mattress cover is absolutely wonderful. One-inch thick and quilted with gel memory foam, it prevents you from sweating at night and cradles you into the softest of sleep. Ever wondered what sleeping on a cloud might feel like? This must be about as close as it gets!

3″ Energex™ Temperature Responsive Foam

I don’t even know where to start with the Energex™ Temperature Responsive Foam layer. I am so impressed with it and Nest Bedding’s R&D department overdid themselves! Those 3 inches of foam are a very responsive alternative to conventional visco memory foam. It provides the perfect amount of  pressure relief and responsiveness, so you never feel like you’re stuck in your mattress. Because of its open cell polymer, it also remains cool at night. But best of all, you can unzip the quilted mattress cover and replace the Energex™ Temperature Responsive Foam with a plusher or firmer layer to match your current sleeping preference. And when you think you are ready for a new mattress, simply exchange that layer of foam for a new one, and avoid sending your mattress to the landfill, while benefitting from a brand new mattress feel for a portion of the cost of a new mattress!

Transition Foam Layers

You will find 2 thin layers of transition foam in the Nest Bedding Sparrow Mattress. One to transition you from the soft Energex™ Temperature Responsive Foam to the supportive coils. And one underneath the coils as an outlet for the coils to compress into, adding life to your Nest Bedding mattress. 

6″ Pocketed Coils

The pocketed coils in the Nest Bedding Sparrow Mattress provide strong and healthy support to your spine throughout the night. It helps align your back and ensures that your high-pressure areas feel supported under the foam.

Nest Bedding Sparrow Sleep Tests

Everything we felt in one box

Firmness Temperature Maintenance Sleeping Style Bed Base
You can purchase the Nest Bedding Sparrow mattress in three firmness levels, by choosing one of 3 Energex™ Temperature Responsive Foams. The best-seller Medium Energex™ Temperature Responsive Foam is the one we tested and we rated it a 6.5/10 on the firmness scale, which ranks right about average on the firmness scale. The Plush option is a much softer option, while the Lux Firm offers firmer sleep. Note that, upon receiving your mattress, you have 100 nights to participate in the free exchange program. Unhappy with the firmness of your mattress, ask for a free exchange into one of the other 2 Energex™ Temperature Responsive Foams!
The Nest Bedding Sparrow mattress cover is quilted and infused with a cooling gel memory foam that keeps you from sleeping hot at night. That THERMIC® phase change cover, coupled with the open cell Energex™ Temperature Responsive Foam right underneath it, ensures a cool night of sleep. We never felt hot on the Nest Bedding Sparrow mattress and it is on the cooler end of the dozens of mattresses we have tested.
In case of a stain, try to tend to it as quickly as possible. Blot excess liquid with a cloth, then gently spot clean with a clean cloth, clear water, and mild detergent. Never rub, as that could spread the stain further. I always recommend protecting your investment with a mattress protector!
Your Nest Bedding Sparrow Mattress can fit all sleeping styles, depending on the Energex™ Temperature Responsive Foam layer you order with it! The Medium firmness will work really well with back sleepers and lighter-weight side-sleepers. If you love lots of plushness, are a heavier-weight side-sleeper, or need extra pressure relief, go with the Plush foam! The Lux Firm will work great for back and stomach-sleepers. Side-sleepers will find it too firm and it might create shoulder / hip pain.
You can lay your Nest Bedding Sparrow Mattress on any flat base - slats, box spring, foundation, adjustable bases, and even the floor will work great with this mattress.

Detailed Nest Bedding Sparrow Review Conclusion

We have absolutely loved the Nest Bedding Sparrow and it is becoming a close call on whether it should become our guest room permanent mattress! It is an ideal mattress for couples, hot sleepers, and you can customize it to your personal sleeping style for the most comfort. 

There is so much to love about it and it is, in my opinion, a luxury mattress. It offers an incredible amount of comfort and support, with particularities that make it a bit of a wonder in the mattress world!

Three things I absolutely love about the Nest Bedding Sparrow hybrid mattress: 

  • The 100-night comfort layer exchange program, letting you switch the firmness of your foam layer until you find the best one for your sleeping style
  • The dual firmness option for couples purchasing a King or California King. You get to choose a different firmness level for each side of the mattress if needed
  • Less filling of the landfills and long-term savings since you can replace the foam layer for a new one instead of trashing and getting an entirely new mattress

Who Is Nest Bedding?

There is always something very special about purchasing a product from a family-owned company. Nest Bedding was established in 2011 as a factory-direct bedding and mattress company, and you feel the difference. Purchasing from Nest Bedding comes with a load of service, kindness, and knowledge. 

They believe in the products they place in your home and offer a lifetime warranty on their mattresses. That speaks so highly for the quality of their products! 

Each mattress is made to order and by hand, by Americans, for Americans. Their products are organic and natural, and their prices are very affordable once you consider the quality you are purchasing. 

Nest Bedding’s mattresses do not contain any flame retardant chemicals, which is a wonderful plus. They use hydrated silica as a fire barrier in the entire mattress – a fabric woven with inert silica, which is a naturally occurring element.

Unlike many mattress-in-the-box companies, they have several showrooms in Los Angeles, San Francisco Bay Area, New York, Chicago, and Seattle for you to get a feel for their mattresses. And if you can’t physically make it to one of their locations, remember that you are getting a 365-night at-home sleep trial to make sure you love your mattress before fully committing (a 2021 upgrade to the 100-night trial)!

What Is Inside The Nest Bedding Sparrow?

The Nest Bedding Sparrow mattress is a 14-inch thick mattress made of a combination of foam and coils, offering incredible comfort and spinal support for a healthy night of sleep. Thanks to its unique exchangeable layer of foam, we can recommend it to all kinds of sleepers. More on that below! Let’s first look at the different layers in more detail: 

The Quilted THERMIC® Mattress Cover

The fully-zippable mattress cover on the Alexander Bedding Sparrow is infused with gel memory foam and quilted. It is a whole inch thick and one of the plushest, most luxurious, mattress covers on the market, and the gel memory foam ensures that you sleep cool.

Energex™ Temperature Responsive Foam

All Nest Bedding foams are made in the USA and CertiPUR-US Certified, meaning that they do not release harmful chemicals in your home. In the Nest Bedding Sparrow mattress, you are getting 3 inches of Energex™ Temperature Responsive Foam in one of 3 firmness levels – Plush, Medium, or Lux Firm. That thick layer of foam is an alternative to conventional disco memory foam. It is open,  which makes it a breathable and naturally cooler layer, further ensuring a cool night of sleep. Additionally, you will find the Energex™ Temperature Responsive Foam layer to be more responsive than traditional foam, making it easier to move around at night. This is a comfort layer you are able to exchange to give your mattress a new or different feel. King and Cal King sizes also give you the option for dual firmness, which is the only mattress I know that offers the option. 

Transition Foam

Transitional foam serves two purposes. It allows a soft transition between the plush foam and supportive coils, and gives an outlet for the coils to compress into, thus lengthening the life of the mattress. You will find a 1-inch layer of transitional foam on either side of the coils inside the Nest Bedding Sparrow. 

Individually-Wrapped Coils 

The Nest Bedding Sparrow has 6 inches of pocketed coils that help provide full spinal support for a healthy night of sleep. They also do a great job at isolating a partner’s motion during the night for a quiet and rested night of sleep. 

How Does The Nest Bedding Sparrow Sleep?


The beauty and uniqueness of the Nest Bedding Sparrow resides in its Energex™ Temperature Responsive Foam. It gives 3 unique firmnesses to your mattress and you have 100 nights to exchange for a different firmness if you are not comfortable on the one you purchased. Here are the firmness scores we are giving each comfort foam layer: 

  • Plush: 4/10
  • Medium: 6.5/10
  • Lux Firm: 8/10

And guess what, couples? If you purchase a King or Cal King size, you can order dual firmness, where each partner customizes his/her side of the bed. With that internal split, if you have a different sleeping style or preference than your partner, you can each get the perfect feeling all in one mattress. 

Sleeping Style

The Nest Bedding Sparrow mattress accommodates different sleeping styles based on the comfort layer you purchase. 

Plush Energex™ Temperature Responsive Foam: this will be the perfect firmness for the side-sleepers looking for deep-pressure relief. It will work especially great if you are a heavier side-sleeper, like extra plushness, or need extra pressure relief in the shoulder or hip areas.

Medium Energex™ Temperature Responsive Foam: the Medium comfort layer is Nest Bedding’s most famous. It is a nice starting point if you are unsure of your preference, or if you order a Queen-size bed and have a partner with a different sleeping style than yours. The Medium foam works really well with back sleepers and lighter-weight side-sleepers. Combo sleepers, who switch positions at night, will really enjoy the Medium as well. 

Luxury Firm Energex™ Temperature Responsive Foam: the firmest of the 3, the Lux Firm will be the most comfortable layer for stomach-sleepers who need to feel like they are floating on top of their mattress. It will work well with back-sleepers who prefer a firmer mattress. Side-sleepers, however, might find the Lux Firm too hard, and could feel shoulder and hip pain in the morning.


The Nest Bedding Sparrow hybrid mattress does an amazing job at keeping you cool at night. 

It uses a gel memory foam infused mattress cover, together with a responsive cool-sleeping open foam to ensure that the foams you sleep on don’t heat up unnecessarily. Your excess body heat is dispersed inside the mattress and the foam layers remain cool throughout the night. If you are a hot sleeper, you will sleep very comfortably on the Nest Bedding Sparrow!

Motion Transfer

With a total of 6 inches of foam, the Nest Bedding Sparrow is a great option for couples. Its 6 inches of individually-wrapped coils do a great job at isolating any motion. If you sleep with a partner, you should not be woken up by his/her movement. 

How Do I Care For The Nest Bedding Sparrow?

The Nest Bedding Sparrow hybrid mattress cover is not machine washable, and I ALWAYS recommend protecting your mattress investment with a waterproof mattress protector.

Spills and accidents unfortunately happen… If you do notice a stain on your Nest Bedding Sparrow mattress, tend to it as quickly as possible with a clean cloth, water and a mild detergent. Spot clean the stain without rubbing it to avoid spreading it. 

Let’s now talk about your Energex™ Temperature Responsive Foam layer. You have ways to ensure it lives a long and happy life, while ripping all of the support and pressure relief benefits for many years. Simply rotate and/or flip it once every 6 months! And while you can’t flip the whole mattress, you can unzip the mattress cover and flip and rotate the foam layer! You will gain 2 to 3 times the life of your comfort layer by doing so!!
