Cover
Let’s start this Sparrow Signature Hybrid mattress review with the cover.
The cover is rather thin and very soft to the touch. However, it has a sturdy feel. It is quilted with gel-infused memory foam, creating a pillow-top surface and making the mattress luxuriously squishy on top. However, because there’s gel foam quilted into the cover, it doesn’t feel too warm even when cradling the protruding body parts. Overall, the cover adds a bit of softness and feels very pleasant to the touch.
It’s also worth mentioning that the Sparrow’s cover feels cool. While it doesn’t really contribute to thermoregulation that much, it prevents the mattress’s surface from getting too warm during the night.
It’s also worth mentioning that the Sparrow’s cover is very well-made. The stitching is neat, with no loose threads or holes. There is also a zipper, which makes this cover removable. The zipper works smoothly and feels pretty sturdy, so it should last for a long time.
A removable cover makes cleaning much easier. While it might not fit into a standard washing machine, it still allows users to treat spots or wash it with their hands. This makes it easier to keep the mattress clean, which is especially crucial for allergy-prone sleepers. The previous variation of this mattress didn’t come with a removable cover, so the Sparrow has evolved to ensure trouble-free cleaning.
Construction
Another crucial aspect I want to show you in my Sparrow Signature Hybrid mattress review is its construction. This hybrid model combines several different materials, so let’s review them in detail.
So, here are the layers of the Sparrow Signature Hybrid mattress by Nest Bedding:
- quilted cover that combines gel-infused foam with Thermic phase-change fabric;
- comfort layer, which uses the company’s proprietary Energex foam (temperature-responsive polyurethane foam that responds a bit faster to applied pressure than traditional memory foam). At the same time, this layer offers extra cushioning for side sleepers and effectively relieves pressure;
- transition layer that uses high-density foam with small air channels in it for improved breathability;
- support layer, which is comprised of independent (wrapped) coils + reinforced coils around the edges;
- base layer that uses dense foam to support the overall construction.
Overall, I am happy with the construction quality of the Sparrow mattress. The materials are sturdy, and everything is sewn together pretty well. Therefore, this is a durable mattress that should easily withstand everyday use.
Firmness
The firmness level is another criteria of today’s Sparrow Signature Hybrid mattress review. While it determines the overall feel of the mattress, it can also affect comfort and support.
Now, the Sparrow Signature Hybrid mattress by Nest Bedding is available in three firmness variations: Plush, Medium, and Firm. Thus, this mattress can accommodate different sleeping styles and body types.
I was testing the Medium model. To me, it felt medium-firm, actually, rated around 6.5 on the firmness scale (with 10 being the stiffest). 
On top, this mattress has that classic pillow-top feel. It is squishy, slow-moving, and hugging. The quilted foam cover gives the Sparrow Signature Hybrid mattress by Nest Bedding a luxurious feel. It also nicely balances out the rest of the construction, offering some extra padding for one’s pressure points.
At the same time, the Sparrow does not feel overly hugging. The responsive coils underneath ensure resilient support, combatting the quicksand feel many foam mattresses are associated with. Therefore, this model has a bit of a bounce, with gentle cradling on top.
Edge Support
Edge support is often overlooked, which is why I want to pay special attention to this characteristic in this review.
Strong edges can offer many benefits, especially for people who sleep near the perimeter of the bed. Luckily, the Sparrow can provide strong edge-to-edge support like most best-rated hybrid mattresses. 
I didn’t feel like rolling off when sleeping near the edge. My body was supported properly, so I didn’t experience any tension build-up either. This means the Sparrow can offer more sleeping space, making it suited for couples.
When sitting on the edge, there was some compression in the top layers. However, I didn’t slide off, which proves how sturdy this mattress’s edges are. Additionally, because the edge coils are reinforced and pretty resilient, they even offer some boost when getting up. Therefore, the Sparrow Signature Hybrid can work for people with some mobility issues (related to back pain, for example).
Motion Transfer
The next aspect I want to talk about is motion transfer. When the mattress materials don’t absorb shock from motion well, partnered sleepers can feel when one of them moves in bed. This can lead to nighttime disturbances, affecting their sleep quality.
Now, like most hybrids, the Sparrow’s motion-absorbing properties are average. It’s not extremely bouncy, but it doesn’t keep shock from motion on one side of the bed either. Therefore, It may work for couples who aren’t that easily disturbed during the night. The Sparrow might also suit sleepers who don’t toss and turn in bed that much.
Of course, if there’s a significant weight difference between you and your partner (or one of you is a petite sleeper), it’s better to look for a less resilient model. You can check out our review of the Puffy mattress, which is more hugging but doesn’t feel like quicksand (unlike many other memory foam models).
How It Feels for Different Types of Sleepers
I also want to look at how the Sparrow mattress would perform for different sleeper types as one mattress cannot suit everyone.
So, here’s how the Medium variation of the Sparrow Signature Hybrid would work for the following categories of people:
- Side sleepers. Because the Sparrow has thick
comfort layers, I felt perfectly fine lying on it on one side. The quilted cover creates a pillow-top feel, which offers additional cradling for side sleepers. That being said, some people might prefer a softer model (especially petite individuals who are used to plush beds). They might want to check these mattresses for lightweight people instead. - Back sleepers. I think the Sparrow Signature
Hybrid is a perfect solution for back sleepers. This model has adaptive comfort layers that supported my lumbar curve, keeping my back neutral and tension-free. I also appreciate how the pillow-top cover cradled my hips. However, I would recommend overweight back sleepers to choose the Firm option. - Stomach sleepers. The Medium Sparrow isn’t
very firm, but I felt surprisingly comfy sleeping on it on my stomach. My hips and stomach didn’t sink that deeply, so there wasn’t a painful curvature in the spine. I also think it would work for petite stomach sleepers. As for the heavier individuals (over 230 pounds), they might want to go with the Firm variation.
Other Important Information
I want to dedicate the next part of my review to a couple of technical details that might be crucial for many people.
First of all, let’s talk about the Nest Bedding’s warranty. The Sparrow mattress is covered by a lifetime warranty, which is relatively rare. Most brands offer 10-15 years of coverage. For instance, the famous Purple and Tempur-Pedic mattresses come with a 10-year warranty.
The Sparrow Signature Hybrid also stands out from the crowd thanks to the sleep trial it comes with. Shoppers can test this mattress for a whole year and return it for free if they don’t love it. That’s quite impressive, given that the industry standard is 100 or 120 days of in-home trials. Seems like Nest Bedding takes an extra step to ensure customer satisfaction.
I would also like to note that the Sparrow arrived with almost zero off-gassing, which is something most mattresses can’t boast of. It dissipated within a few hours, which is faster than average (especially among mattresses that contain foam).
Summary
The Sparrow Signature Hybrid by Nest Bedding can be considered a luxurious mattress on the mass market. It has a pillow-top design giving it an extra-comfy feel. Additionally, it’s available in three firmness variations to accommodate more types of sleepers. Finally, the Sparrow is very well-made, so it can be a long-lasting investment for people who want great value.
Pros:
- Sturdy, durable construction;
- Zippered cover for fuss-free cleaning;
- Balanced feel, nicely combines cradling foams with responsive coils;
- Strong edges, offering more sleeping space;

Cons:
- Slight motion transfer is possible (more significant if there’s a big weight difference between the sleepers);
- Not very cooling, which might be an issue for chronic hot sleepers;
- Heavier than memory foam models (which is common among hybrid mattresses).
