All in all: The Sparrow Signature Hybrid mattress from Nest Bedding (formerly, the Alexander Signature Hybrid) comes in plush, medium, and luxury firm options. We tested the medium option, and found it to be highly responsive, cooling, and supportive. Thanks to the multiple firmness options, it can support a variety of sleeping positions.

Mattress Lab Scores

We test each mattress in our sleep lab for performance, functionality, and social responsibility. The total score is a weighted average of all 14 category scores. You can read more about our review process here.

Responsiveness 

To test responsiveness—or how quickly a mattress adjusts to your changes in position—we ask our testers to lie on the mattress in each sleeping position and score how easily the mattress settles into the new position.

A score of one means the mattress takes a long time to adjust, while a score of 10 means the mattress adjusted perfectly to the new position. Overall, our testers gave the Sparrow a near perfect score of 9.5/10 for responsiveness.

Motion Transfer

Our motion transfer tests tell us how well a mattress absorbs movement across the mattress surface. The wine test is a visual indicator of how much motion is transferred from one side of the bed to another. We placed a glass of wine on the mattress surface and asked a tester to move around. The glass swayed quite a bit, but stayed standing, so we gave the Sparrow a score of 6/10 for that test. 

Next, we swapped the wine for another person. Our testers rated the Sparrow a 6.75/10 for this portion of the test, with one meaning tons of movement and 10 meaning no movement at all. The total motion transfer score averaged out at 6.4/10, so the Sparrow mattress does a moderate job of isolating motion.

Firmness Levels

The plush option is very soft— about 3/10 on the firmness scale. The medium is a 4.5/10, so it’s closer to a medium-soft. The luxury firm is about 7/10 on the firmness scale, which is considered medium firm by some. We tested the medium mattress and felt like it was a great option for various sleepers since it’s the right balance of soft and firm.

Will Your Sleeping Position Be Supported?

Side sleepers will get the best pressure point relief on the plush option, and stomach sleepers need the extra support of the firm option. Back sleepers will feel the most comfortable on either the medium or luxury firm option. 

Temperature Regulation

We found the Sparrow Signature Hybrid to sleep cool, though it’s not distinctly cool-to-touch. Hybrid and innerspring mattresses tend to sleep much cooler than all-foam mattresses because of airflow through the coil layer. 

The Sparrow pairs a breathable coil layer with gel-infused foam and phase change materials in the mattress cover—both of which work to regulate the temperature of the mattress surface. 

Weight Capacity

The Sparrow can comfortably support up to 600 lbs, or 300 lbs on both sides. 

Foundation Compatibility

Using the right support system for the Sparrow mattress will give you the best sleep quality and prevent mattress sinkage. Make sure your mattress foundation is flat, firm, and non-flexible. Box springs aren’t the best fit, but you can use platform beds, adjustable bases, and slatted beds (no more than 4” between the slats).

A Look Inside

The Sparrow mattress blends three foam layers with individually wrapped pocketed coils.

What It’s Like to Unbox?

The Sparrow Signature Hybrid mattress is delivered compressed, rolled, and packaged in a box inside a box. It took us just under two minutes to set it up. A queen size weighs 105 lbs, so you may want to enlist help setting up your mattress, but it comes with handles on the side, making easy lifting. The first thing we noticed once the mattress was on our bed frame was its pretty criss-cross design on the quilted cover. It also had a minor off-gassing scent when we cut off the plastic packaging, but it went away quickly. The mattress took a little bit of time to puff up so you may not want to sleep on it right away.

Free Shipping

Nest Bedding ships their mattresses for free in the lower 48 states (there’s an extra fee if you’re shipping to Alaska or Hawaii). Get your bedroom ready because your mattress will arrive within 4–8 business days. You’ll receive a tracking number after your order has shipped, but you don’t need to sign for your package.

If you need help setting up your bed set, call the Nest Bedding team at 888–992–2001 for a quote for white glove delivery. Mattress removal may be available for an additional fee.

365 Nights to Try It

You can take up to 365 days to decide whether or not the Sparrow is the most comfortable mattress for you. A one-year sleep trial is longer than average for the mattress industry, and gives your body plenty of time to adjust to a new sleeping surface. 

What the Warranty Covers

If your Sparrow mattress develops indentations deeper than 1” or defects in the mattress cover/zipper, you may be able to receive a replacement mattress or repair services under the lifetime warranty.

For the warranty to apply, you have to be the original owner of the mattress and have purchased it directly from Nest Bedding or one of their authorized retailers. Email customerservice@nestbedding.com to submit a claim. Within 7 business days, a rep will reach out to you with instructions on how to proceed.

Lifetime Renewal Exchange

Recently, Nest Bedding has begun offering a Lifetime Renewal Exchange program for its luxury mattresses to provide new life to your mattress. This includes the Sparrow Signature Hybrid, Owl Natural Latex Hybrid, and Finch Natural Latex mattresses. Customers can redeem their one-time comfort guarantee exchange any time after their first 365 days of owning their Nest mattress by contacting the customer service team. A new comfort layer will be shipped to your address, which you can add to your mattress by unzipping and removing your old layer. The Lifetime Renewal Exchange helps reduce waste since it allows you to continue using your Nest mattress.

How to Reach Customer Service

We had a really nice experience with the Nest Bedding customer service team. You’ll need a Facebook Messenger account to chat live with a rep, and you can also reach them over phone or email.

• 888–992–2001, Monday-Friday 8AM–7PM PST, Saturday-Sunday 7PM–6PM PST
• customerservice@nestbedding.com, Monday-Friday 7AM–5PM PST, Saturday-Sunday 8AM–7PM PST

The Return Policy

Nest Bedding’s return policy enables you to request free returns or exchanges during the trial period. After day 30 of the trial period, you can request a return or exchange for a different firmness level. Just keep in mind that your trial period doesn’t restart when you make an exchange, and you can only request one exchange or return per customer, per year.

To start the return or exchange process, email the Nest Bedding team at customerservice@nestbedding.com. They’ll work with you to arrange for your original mattress to be picked up and disposed of or donated. You’ll see your full refund back on your original form of payment after mattress pick up.

Should You Buy It?

The Sparrow mattress from Nest Bedding is a fair choice for the average hybrid mattress shopper with a moderate budget. It’s durable, protected by a lifetime warranty, and available in different firmness options to suit every kind of sleeper. We’re confident that most sleepers will get a good night’s sleep on this bed, but couples concerned about motion transfer should check out our Zoma Hybrid mattress review; it may be a better fit.

See How It Stacks Up

Generally, the Sparrow Signature Hybrid is more responsive than similar mattresses, but doesn’t provide as much motion isolation. It’s also a relatively affordable option with a lifetime warranty that’s tough to beat.

A close comparison is the Beautyrest Black mattress, which has a very similar construction, but received much higher scores for motion isolation and pressure relief. On the flip side, the Sparrow earned much higher marks for responsiveness and is considerably cheaper. If you’re interested, look at our full Beautyrest Black mattress review.

The Casper Wave Hybrid mattress matched the responsiveness score of the Sparrow and earned higher scores in every other performance category, but again, you’ll pay about $600 to $1,000 more for the Casper Wave and will be protected by only a 10-year warranty. Our Casper Wave Hybrid mattress review will tell you all you need to know.

Finally, we’ll bring it closer to home with the Owl Hybrid Latex mattress (formerly the Natural Hybrid Latex). This Nest Bedding mattress model swaps memory foam for natural latex. That change marginally improves motion transfer and noticeably enhances pressure relief. Read our Owl Hybrid Latex mattress review for more information.
