Nest Bedding and Casper are two of the most well-respected online mattress brands. Both companies are known for producing high-quality beds at affordable prices. In this post, we break down the pros and cons of the Nest Alexander Signature and Original Casper to help you make a more informed decision on your next bed purchase.

Nest Alexander Signature vs Casper Synopsis

If you’re in a rush, we got you covered. Here are the primary differences between these two beds.

UPDATE: Nest recently changed their Signature Series mattress so that it has less of a memory foam feel and is now flippable. You can see all of the new details on Nest Bedding’s website.

  • Lifetime Warranty — The Nest Alexander is protected by a lifetime warranty. The Casper mattress is backed by a 10-year warranty.
  • Firmness Options — The Nest Alexander is available in multiple firmness levels, while Casper comes in just one (medium).
  • Feel — Nest Bedding has a slight memory foam feel, and Casper has a neutral foam feel.
  • Price — Casper is a good deal more affordable with and without discounts.

Those are just the quick headlines, though. There’s a lot more you’ll want to consider before buying a new mattress. Keep reading to learn more.

Before we get into the advantages that the Nest Alexander Signature provides, it’s important to note the bed comes in two different firmness levels, but both are on the same mattress (i.e. it’s flippable). You can choose between a “Medium” and “Firm” feel with the “Medium” side being the most popular. That’s the model we’ve spent the most time with, although, we’ve obviously tried out the “Firm” side as well.

Additionally, Nest Bedding also offers an Alexander Hybrid mattress. This model is very similar to the all-foam Signature model except it includes pocketed coils for additional support. We’d recommend checking out our full Nest Alexander Hybrid review for additional details.

However, for the purposes of this comparison, we’ll be primarily focusing on the flagship Signature Series mattress since it’s closer in construction to the Original Casper mattress.

Soft Foam Feel With Dual Firmness Levels

The primary difference between Casper and the Nest Alexander Signature comes down to firmness and feel. The Nest Alexander Signature uses various softer foams, but its “Medium” side and “Firm” side are still a tad firmer than Casper. As you lay down, you sort of nestle into the bed and the top layers start to conform to your body’s shape.

Nest Alexander is unique and absolutely worth your consideration

Overall, the Nest Alexander mattresses (all-foam and hybrid) are two of our team’s favorite beds. Pretty much all the team members here at the Slumber Yard find the Nest Alexander beds extremely comfortable. They even made our list for the Best Online Mattresses In A Box.

Bottom line, if you want a luxury, double-sided mattress, there’s a very good chance you’ll dig the Nest Alexander Signature mattress.

Options For Heavy Individuals

If you’re a large sleeper (250+ lb), the beds are somewhat tied. Both are thicker than your average online mattress, however, we might give the slight edge to Nest Bedding since the bed has the “Firm” side.

With that said, as of early 2019 Casper has two hybrid options you can choose from, meaning beds with coils. They tend to be more durable and provide more support than all-foam beds. You have the option between Casper Hybrid and Wave Hybrid, and they’re both perfectly suitable for heavy-set individuals so we think you should look into them. You can see the new hybrid options on Casper’s website.

Big sleepers could also check out the Nest Alexander Hybrid, which also contains coils, and is one of the most comfortable mattresses out there.

Lifetime Warranty With Nest Bedding

This might a be smaller point, but we thought it was worth mentioning again. The Nest Alexander Signature comes with a lifetime warranty. This is big for consumers who want long-term protection.

Casper Has A Neutral-Foam Feel

Casper has a soft, neutral-foam feel. Technically, the Casper mattress does include memory foam, but it’s used as the second layer of the bed for pressure relief purposes. The top layer is comprised of an open-cell proprietary foam, which drowns out the memory foam feel a little. The result is a very soft foam feel that is extremely comfortable.

What we mean by the term “neutral-foam feel” is that the top layers don’t quite conform and hug your body the way memory foam does. As such, we’ve found that Casper pleases a wide variety of sleepers. People who hate memory foam like the feel of Casper, as do people who generally like the feel of memory foam. It’s just a very accommodating mattress.

Casper Is More Affordable

This one is pretty straightforward. A queen size Casper will cost you about $1,100, while a queen size Nest Alexander will also run you about $1,600.

However, those are just the MSRP prices. Both companies regularly run sales and offer coupon codes. Check the the table at the top of the page to see what kind of deals the companies are currently offering. Chances are you can snag the Casper mattress for about $50-$100 less and the Nest Alexander for ~$200 less than MSRP.

What Casper And Nest Alexander Have In Common

Above we described the primary differences between the two beds, but you also might be wondering what the two beds have in common. Let’s cover that next.


The top layers on the Casper mattress snap back to position almost immediately after pressure is released. The Nest Alexander Signature mattress has basically the same story, though, the “Firm” side has near immediate response times.

This is important for active sleepers who tend to move around a lot. These types of sleepers will generally find it much easier to switch between sleeping positions on responsive beds.

Both Beds Accommodate All Sleeper Types

The nice thing about both Casper and the Nest Alexander Signature is that they are ideal for all sleeper types. It doesn’t matter whether you consider yourself a primary back, side, or stomach sleeper.

The Casper mattress, despite only coming in one firmness level, finds a nice balance between support and pressure relief. Side sleepers will find the mattress very soft and comfortable for their hips and shoulders, while back and stomach sleepers will find that the bed provides a good amount of support under their lower back and trunk.

Nest is a little different because you’ll have to choose your firmness level. If you’re a side or combo sleeper, we’d recommend going with the “Medium” side. If you’re primarily a back or stomach sleeper, we’d recommend going with the “Firm” option for maximum support.

Again, your weight plays a big role here, as well. The recommendations above are for petite and average sized sleepers. We’d recommend large folks check out our list of the Best Beds for Heavy People.

Motion Isolation

Another commonality between Casper and the Nest Alexander is that both beds isolate motion well. Both mattresses passed our test with flying colors. We noticed very little motion transferred from one side of the mattress to the other.

This is another important consideration for couples. Good motion isolation means you’ll feel less of your partner’s movements throughout the night. No sleeper wants to be woken up and disturbed every time their partner rolls over or gets up off the bed. That can be quite frustrating. Luckily, that won’t happen with either of these mattresses.

Casper Mattress vs Nest Bedding Review Verdict

If you’ve made it this far, you now understand the primary differences between these two beds. However, we understand shopping for a new mattress can be confusing and frustrating so if you’re still stuck, ask yourself a few questions. This should help clear things up.

First, what type of feel do you prefer? If you’re a big fan of memory foam, the Nest Alexander Signature has a slight memory foam feel on the “Medium” side. If you don’t like memory foam, chances are you’ll like Casper.

Next, do like the security of a Lifetime Warranty? Nest Bedding has a generous warranty policy, longer than most online mattress brands.

Lastly, do you want the option to choose your firmness level? Nest Bedding has multiple levels to choose from.

That’s all we’ve got for you. We hope the comparison was helpful. Thanks for choosing the Slumber Yard.

Shipping, Returns, Trial Periods, And Warranties

Buying a new mattress online is super easy these days. You no longer have to spend hours at your local mattress store testing beds for 20 seconds at a time. Below we’ll discuss just how easy the whole process is. Let’s first start with Casper.

The Casper mattress ships for free and arrives at your home compressed and rolled up in a box. Once it arrives, simply move the box to your room and unroll the mattress onto your bed frame. Make sure to let the bed fully inflate for about 24-72 hours before your sleep on it.

Once the mattress is delivered, Casper gives you a 100-night risk-free trial period. Basically, the company is giving you more than three months to test the bed in the comfort of your own home and truly decide whether you like it. That’s a lot better than 20 seconds in your local mattress store.

During the trial period, if you decide the Casper mattress isn’t for you, no worries, just give the company a call and they’ll take care of everything. First, they’ll arrange for a third party service to pick up the mattress from your home. Once that happens, just provide proof to Casper that the mattress has indeed been picked up and they’ll issue you a full refund. The whole return/refund process normally takes around 2-3 weeks. Casper also backs their mattress with a 10-year warranty. You can read more about it on Casper’s website.

Nest Bedding, like Casper, makes it extremely easy for consumers. They too offer free shipping and a 100-night trial period. If, after 30 days, you decide the Nest Alexander isn’t for you, the return and refund process works the same way as described above.

However, unlike Casper, Nest Bedding backs their mattresses with a lifetime warranty. That’s pretty unique. We’ve only run across a couple online mattresses that are backed by such a policy. You can read more about it on the Nest Bedding’s website.

Nest Bedding also offers what they call a Lifetime Comfort Guarantee. Basically, once the trial period has expired, if you suddenly decide you don’t like the mattress, the company will allow you to purchase a different model for 50% of the current retail price. Pretty cool, right?
