Honest YouTube GhostBed Flex Review

As many of our loyal subscribers know, we love producing videos here at The Slumber Yard. Here is a quick video review that covers what you need to know about the GhostBed hybrid mattress.

It’s always a good idea to cover all your bases when talking about a large purchase like a new mattress, though. Keep reading to learn more about the Flex mattress.

Policies For The GhostBed Flex Mattress

A big reason why online bed-in-a-box companies like GhostBed, Purple and Casper have been able to steal a large portion of market share from brick and mortar retailers is due to the generous polices they offer consumers. In short, these new age, direct-to-consumer bedding companies make it very easy and convenient for consumers to test and purchase their products. Let’s jump into the details of GhostBed’s policies so you have a better idea of how this whole mattress-in-a-box concept works.

First, the GhostBed Flex mattress comes with free shipping and will arrive at your home or apartment vacuum-compressed and rolled-up in a medium-sized box. This type of delivery makes it super easy for consumers. You no longer have to bother your friends to borrow a truck or beg them to help you move a floppy mattress up flights of stairs. Once you move the box to your room, all you have to do is remove the bed, cut the plastic and then sit back and watch it magically inflate. Keep in mind, it often takes a couple days for the bed to fully inflate and expand to its true size. According to GhostBed, it may even take up to five days in extremely cold climates.

Starting the day the bed is delivered, GhostBed offers customers a 101 night risk-free sleep trial. In simple terms, the company allows you sleep on the bed for more than three months before making a final decision on whether you want to keep it or not. If you end up liking the Flex mattress, great, it comes backed by a 25 year warranty, which protects against material failures and structural defects. If you want to learn more about what exactly the warranty entails, we recommend visiting the company’s website.

If you decide the Flex mattress isn’t quite right for you after testing it for at least 30 nights, no problem, the return/refund process is very simple. Just contact the GhostBed customer support team and they’ll schedule a time for a third party logistics company to come retrieve the bed. After the pick-up has taken place, the company will issue you a full refund. It’s as easy as that. You’re probably now starting to see why bed-in-a-box companies are becoming so popular.

Also, just you know, the majority of online mattress companies offer free shipping, free returns, a 100 night trial period and a 10 year warranty. Obviously, GhostBed meets these standards except they go above and beyond by offering a significantly longer warranty.

What Is The GhostBed Flex Made Of?

To put it simply, the GhostBed Flex is a beast of a mattress. It’s comprised of six different layers and totals a whopping 13″ thick.

For the bottom layer, the bed uses a 1″ layer of high density support foam. From a practical standpoint, you won’t even notice this layer. It’s more so there to serve as a foundation for the coils above. On that note, the next layer is comprised of sturdy 8.5″ individually wrapped coils, which give the bed a strong support framework. GhostBed also made sure to include reinforced coils along the perimeter of the bed to ensure sleepers receive solid edge support as they roll-over towards the sides.

On top of the coils is a 1″ layer of soft transition foam. As the name implies, this layer is simply there to serve as a transition from the firm steel coils below. Next, GhostBed uses two separate 1″ layers of gel memory foam, which combined provide sleepers with pressure relief and act as the true comfort layers for the bed.

Finally, within the cover, GhostBed uses a special cooling fabric, which is supposed to help you sleep cool throughout the night. We’ve seen this before with GhostBed. Their Luxe mattress uses a similar type of material in its cover to help regulate heat.

Overall, we’re pretty impressed with the construction of the Flex mattress. If you’re looking for a thick, durable bed that will last a long time, the Flex definitely fits the bill.

Pricing & Coupon Code

In terms of price, the GhostBed Flex is a little more expensive than the typical bed-in-a-box but honestly that’s expected given its high-quality construction. This isn’t your typical budget all-foam mattress like Tuft & Needle. So with that in mind, we actually think the Flex is a pretty decent value, especially compared to similar beds that you would find in your local brick and mortar mattress store. Here’s how pricing breaks down by size.

SizePrice (MSRP)
Twin XL$1,250
California King$1,825

By the way, don’t let the pricing above scare you off. GhostBed is almost always running some sort of sale or promotion to make their beds more affordable. On average, we’d say expect to receive at least a $100 discount on your purchase. However, we have seen the company offer even larger discounts in the past. It might be a good idea to check what the current promotion is on the GhostBed website.

Alternatively, if the Flex mattress is out of your price range even with the discount, no need to fret, we got you covered. Be sure to check out our hand-selected list of the Best Cheap Mattresses on the market.

Analysis Of Feel & Firmness

Although the bed uses multiple layers of memory foam, we wouldn’t consider the Flex mattress to be a pure play memory foam mattress. Don’t get me wrong, you can definitely tell the bed uses memory foam when you’re laying down but overall, we’d say the bed has more of a neutral feel to it. The top layers just don’t conform and contour to your body as much as the top layers on the Layla or Nectar mattresses, for example. I guess the best way to describe the feel the of the Flex mattress would be that it has a neutral-foam feel with a hint of memory foam.

Soft, neutral-foam feel with a hint of memory foam

All in all, it’s an extremely comfortable mattress. We like the fact that it sort of tows the line between memory foam and neutral foam. We think it lands near the center of fairway for a lot of consumers out there. People who like memory foam will enjoy the mattress as will people who generally dislike memory foam. I guess you could say the GhostBed Flex is the mattress equivalent to Dwayne “The Rock” Johnson. In other words, the vast majority of people will like the bed.

The other nice thing about the GhostBed Flex is that it’s easy to switch between sleeping positions. Our testing team didn’t really notice much resistance when they went to switch from their back to their stomach or their side to their back, for example. This is good news for active sleepers who tend to move around a lot throughout the night.

In terms of firmness, we think the GhostBed Flex mattress lands around a medium on the soft-to-firm scale. At the end of the day, it’s a very accommodating mattress that offers a nice symmetry between pressure relief and support.

Keep in mind, the above firmness designation is based on an average sized person. Heavier folks will likely find the GhostBed Flex feels a little softer (probably more in the medium-soft range), while more petite folks will likely find it feels a tad bit firmer (probably closer to medium-firm).

Suitable Body Types

Based on the construction and firmness profile of the mattress, we think the GhostBed Flex will accommodate people of all shapes and sizes. It doesn’t matter whether you weigh 100 pounds soaking wet or 300 pounds after a five day all-juice diet. The 8.5″ individually wrapped coils in the bed provide more than enough support.

However, keep in mind, although the mattress properly supports all body types, that doesn’t mean the bed will feel the same to every person. In general, heavier individuals tend to feel like most mattresses are on the softer end of the spectrum since they exert more force and sink into the soft top layers more than average or petite sized individuals.

Speaking of smaller sized individuals, they typically feel like most beds are on the firmer end of the spectrum given they exert very little pressure and sleep more on top of the surface. Keep your body weight in mind as you progress through this review.

Side Sleepers

The GhostBed Flex mattress is a good option for people who spend a lot of time on their side. The bed is soft-to-the-touch and offers a good amount of pressure relief.

The top layers don’t quite form to your body’s shape like the top layers on traditional memory foam beds yet they still do a pretty good job of cradling your hips and shoulders. Our testing team never experienced any sort of discomfort around their pressure points. Overall, we’d give the Flex mattress a thumbs up in the side sleeper department.

Back And Stomach Sleepers

Similar story here. We think the GhostBed Flex mattress is a good choice for back and stomach sleepers as well. The bed provides a good amount of support overall.

Our testing team (even the heavier individuals) thought the mattress did a good job of keeping their hips and trunk in proper alignment. No one complained of waking up with a sore lower back or anything like that.

Combination Sleepers

Based on the previous two sections, you can probably guess what we’re going to say here. Yes, we think the GhostBed Flex will work for combo sleepers who rotate between their back, stomach and side throughout the night.

As we mentioned above, the bed just offers a nice balance between comfort and support. Plus, there’s very little resistance when you go to switch positions. That means you won’t ever feel like you’re stuck-in-the-bed.

Temperature Regulation Anlaysis

After testing out the bed, we feel that the GhostBed Flex mattress sleeps temperature neutral. We know the bed incorporates special cooling materials but at the end of the day, we just didn’t feel strongly enough to to give it the cooling mattress designation. That’s not necessarily a bad thing by the way. We just think the mattress won’t be the primary reason why you cool down or warm up throughout the night. If you are looking for a cooling bed, you should check out the GhostBed Luxe, which the company claims is the coolest mattress on earth.

Keep in mind, temperature regulation is a delicate subject in the mattress industry. A lot of companies like to toss around scientific terms and claim their beds sleep cool but the truth is external factors often play more of a role in terms of how warm or cool you sleep. To use an example, it doesn’t matter what kind of special cooling materials a bed uses if you live in Arizona and refuse to turn on your air conditioner during the summer.

Obviously, that was a severe example but I more so just wanted to get the point across so you understand that your mattress isn’t everything when it comes to temperature regulation. Other common factors that affect how warm or cool you sleep include the types of sheets you use, what you wear to bed and how often you cuddle with your partner.

Will Couples Like The GhostBed Hybrid Mattress?

Individuals who share their bed with a partner or pet will be just fine on the GhostBed Flex mattress. The bed performs well when it comes to motion isolation and edge support, which are two of the most important factors for couples to consider when mattress shopping.

First, the bed does a pretty decent job of deadening movement. The test below is supposed to mimic your partner rolling around and creating movement throughout the night.

As you can see above, the water in the glass stays somewhat steady despite the intense movement, which is a good sign the mattress will be able to isolate the motion originating from your partner. In turn, this will hopefully lead to a more restful night of sleep since you won’t be disturbed every time your partner goes to switch positions or gets up out of bed.

In terms of edge support, the Flex mattress gets a very high grade. The perimeter of the bed is solid. As you inch towards the side of the mattress, you feel properly supported and never as if you’re going to roll-off.

This is an important topic for couples who split a full or queen size mattress. In these types of situations, couples will want a bed with solid edge support so they can use the entire surface area of the bed.

GhostBed Flex Review Verdict

All in all, we were pretty impressed by the GhostBed Flex. In all honesty, we think it’s the best bed GhostBed offers. It’s tough to find many negatives with this mattress. I guess the only thing you can really point to is the price tag. At the end of the day, there are other hybrid beds that are just as accommodating but more affordable. Still, if price really isn’t an issue, it’s tough to beat this bed. Don’t be surprised to see it land on several of our Best Mattress Lists.

GhostBed Flex vs Original Comparison

The Original GhostBed and Flex mattresses are two different animals. Here’s a quick overview of how they compare.

  • Price – The Original GhostBed mattress is quite a bit more affordable than the Flex mattress. For example, a queen size Original GhostBed is about $500 less than a queen size Flex mattress (based on MSRP).
  • Construction – As you read earlier in the review, the Flex mattress has a durable, hybrid construction. The Original GhostBed mattress, on the other hand, is comprised entirely of foam. The differences don’t stop there. The Original model also incorporates a layer of aerated latex foam.
  • Body Type – Given the constructions of each mattress, we’d have to give the edge to the Flex for large body types. It’s just going to be more supportive for heavy people, plain and simple. Small and medium sized folks will be fine on either mattress though.
  • Feel – Both mattresses have what we consider to be a neutral-foam feel, however, with the Flex mattress you do get a hint of memory foam.

In our eyes, the decision between these two beds really comes down to your budget, weight and what type of feel you want.

How did the Slumber Yard team get this mattress?

The company sent the Slumber Yard team a free sample unit for testing purposes. We retain full editorial control over the content we produce. In other words, the views and opinions stated in this review are those of the Slumber Yard team.

Where is the Flex mattress made?

GhostBed manufactures its beds right here in the United States. GhostBed’s parent company, Nature’s Sleep, is a well known bedding company that has been around for decades.

Does the GhostBed Flex require a special frame?

No, the GhostBed Flex mattress is compatible with most box spring foundations, slatted frames and adjustable bases. In other words, you most likely will not need to purchase a new frame. However, with that said, you’ll want to make sure your existing frame or foundation is able to support the weight (see next question) of the mattress as well as you and your partner.

How much does the GhostBed Flex mattress weigh?

The weight of the mattress depends on which size you purchase. It ranges from around 76 pounds for a twin size to around 141 pounds for a California king size.

When will I receive the mattress?

GhostBed typically fulfills new orders within 2-5 business days. Of course, that’s not always the case. Sometimes mother nature and holidays can interfere with shipping times and logistics.

Where does GhostBed ship products?

GhostBed ships for free to the contiguous 48 states. They also ship to Alaska and Hawaii for an additional fee. However, the company does not ship internationally.

Where can I test the GhostBed Flex mattress?

Last we checked, the GhostBed Flex mattress was only available to purchase online. GhostBed does not operate or partner with any brick and mortar mattress retailers. That means you’ll have to rely on the company’s 101 night sleep trial in order to test the bed. Honestly though, that should be more than enough time to decide whether the Flex bed-in-a-box is right for you.

How firm is the GhostBed Flex mattress?

It’s around a “medium” on our soft/firm scale, so it’s not overly firm or soft.

Does it have a cooling cover?

GhostBed Flex has a cool-to-the-touch cover, similar to the one featured on the GhostBed Luxe mattress.
