How is DLX Classic Different?

The DLX Classic hybrid has an overall performance level that is lower than average but with a price tag that is also lower than average—a savings of $339 compared to the average hybrid.

Advantages

Besides price alone, other notably advantages of the DLX are limited. It does offer better-than-average sex performance, thanks to the higher level of bounce.

It also off-gasses slightly faster than average, 5 days vs. the 6-day average.

Perhaps the most significant advantage is the flippable design. The DLX has a quilted comfort layer on both sides of the mattress. This allows you to periodically flip the mattress over, which may help extend the longevity of the mattress.

Neutral Factors

This mattress has moderate sinkage and high levels of bounce. These are considered neutral factors as all sleepers will perceive them differently (some to be pros and others to be cons).

Disadvantages

Disadvantages of the DLX include fair cooling, higher levels of motion transfer, and a full recovery time that is slightly slower than average.

This mattress only has a 2.25″ comfort layer, which certainly contributes to the pressure relief issues we noted in our performance tests.

The DLX Classic has fair cooling. During our tests, I felt a moderate to significant level of heat retention around my body.

• Baseline Temperature – the temperature of the mattress before anyone lies on it
• Maximum Temperature (0 minute) – the temperature of the mattress after lying on it for 15 minutes
• Ending Temperature (5 minute) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

The mattress is equipped with 2.25” of comfort material on the top and bottom that sandwich an 8.0” coil unit.

While the coils definitely help to improve cooling, we still have a fairly thick quilted cover. That cover appears to retain a notable level of heat and doesn’t seem to breathe particularly well.

Unfortunately, mattresses within this price range just aren’t able to utilize higher performance foams or cooling covers, both of which limit the cooling performance.

In our objective temperature tests, we measured a max surface level temperature of 92.5° F. This is 2.8° more than the average of 89.7° F, based on all of our tests to date.

In addition, after getting off the mattress the temperature declined by 4.8 degrees from minutes 0 to 1, which is 0.1° cooler than average. However, when we consider the fact that the max temp was 2.8° warmer than average it is a notable red flag that the 0 to 1 minute temperature decline wasn’t better.

Heat Dissipation Over Time

In my view, this speaks to a mattress that has difficult breathing and releasing heat. When we consider the combination of objective data, my subjective experiences, and an analysis of the materials, I’m confident in my view that cooling is fair.

The DLX Classic has moderate sinkage. During our tests, we measured a pressure point sinkage depth of 2.06″. This is 0.09″ less sinkage than the average sinkage depth of 2.15″, based on all of our tests to date.

The level of sinkage is documented in the image below.

The mattress creates more of a floating feel where the body lies more “on” the mattress as opposed to sinking down “in” the mattress. This is neither good nor bad, but it is a more specific feel.

The DLX Classic doesn’t have any notable level of body contouring hug. Instead, it creates a more traditional and classic coil feel. This mattress is best suited to the needs of those who like a more traditional coil mattress experience with more of a floating feel and minimal body contouring hug.

The DLX Classic has a moderate level of motion transfer. During our tests, we measured a total acceleration range of 9.59 m/s². This is 9% more motion transfer than the average of 8.80 m/s².

The mattress has a few design and material choices that are negatively impacting motion, including the floating feel, relatively thin 2.25” comfort layer (average comfort layer thickness is 4.1”), and higher-than-average bounce.

All of these factors help to push motion transfer beyond the average.

The level of motion transfer is also documented in the video below.

In our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.14 seconds. In addition, we see a secondary spike from 0.57 to 0.79 seconds.

Finally, by 1.58 seconds we return to near-zero levels of energy. If there is a silver lining for motion transfer, it’s that the motion peaks were only modestly higher than average.

However, that’s where the good news ends. The DLX has a substantial secondary motion spike and a level of motion duration that far exceeds the average.

The mattresses with the least motion are able to disperse energy within 0.3 to 0.5 seconds. More typical mattresses are in the 0.6 to 0.9 seconds range.

Needless to say, a 1.58-second motion duration is far from ideal. In my view, this experience is far more typical of more traditional coil mattresses.

The DLX Classic is a mixed bag for material responsiveness, with a fast mostly recovered response time and a moderate fully recovered response time.

In our mostly recovered test, we measured a recovery speed of 0.40 seconds, which is exactly the same as the average of 0.40 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 1.2 seconds, which is 0.30 seconds slower than the average of 0.90 seconds.

The level of responsiveness is documented in the video below.

While the bulk of the comfort materials rebound back to shape quickly, some of the materials within the quilted cover take a moment or two to fully recover back to shape.

When it comes to responsiveness, faster is better. Faster responding materials help ensure the mattress is easier to move around on and avoids a “stuck” feeling. Certainly, it would have been nice to see a faster responsiveness.

Even so, when we consider the moderate sinkage depth, floating feel, and high bounce from this mattress, I don’t think the slightly slower material responsiveness will create any issues with feeling stuck in the mattress.

The DLX Classic has a high level of bounce. During our tests, we measured a total bounce height of 11.85″. This is 2.33″ more bounce than the average of 9.52″, based on all of our tests to date.

The mattress uses a notably thinner-than-average comfort layer, while also being equipped with a tall 8.0” coil unit. In addition, the mattress creates more of a floating feel and only has a 2.06” sinkage depth (which is less than the average).

The level of bounce is also documented in the video below.

This combination of factors creates the right conditions to create a high level of bounce and that’s exactly what we measured in our tests.

The higher bounce makes it easier to move around on the mattress, gives it a more traditional feel, and also greatly improves sex performance. However, the higher bounce is also the reason that motion transfer is higher than average.

The DLX Classic has good sitting edge support and fair lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 4.50″. This is 0.45″ more sitting sinkage than the average of 4.05″, based on all of our tests to date.

Certainly, we would have liked to have seen less sitting sinkage compression, but with 4.50” of sitting sinkage it’s not an unreasonable level of sinkage. Notably, the mattress materials don’t collapse while sitting.

The level of edge support while seated is documented in the images below.

Overall, I still feel reasonably well-supported while sitting on the edge.  While lying directly on the edge of the mattress, I felt that the support was fair in all sleeping positions. Simply put, I did not feel tremendously well-supported while lying near the edge.

The level of edge support while lying is documented in the images below.

The problem is that the mattress cover has a fairly dramatic curvature of the materials at the edge. This causes the body to lie angled while on the very edge of the mattress, which just doesn’t create an ideal supportive feel.

Notably, the DLX Classic doesn’t include any type of reinforced edge coils or reinforced support foam along the perimeter.

These material choices are a factor in the good, but not great edge support. Even so, given the price point of this mattress, it’s hard to complain too much.

The DLX Classic has excellent sex performance. On the positive side, bounce is very high, noise is minimal, and pressure relief is good. At 11.85” of total bounce, the DLX Classic has notably more bounce than the average bounce height of 9.52”.

This extra bounce is the greatest single factor helping the DLX to achieve the excellent sex performance score it earned.

Beyond bounce, we measured sitting edge support sinkage at 4.50”. This is a bit worse than average, but still good enough to provide for a robust sexable surface.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	9.9	Very High
Edge Support	20%	8.1	Good
Noise	5%	10	Minimal
Pressure Relief	5%	8.0	Good
Cooling	5%	7.0	Fair

Lastly, cooling is only fair, which does lose the mattress some points for amorous activities. Even so, it’s a relatively small weighted factor when compared to bounce and edge support. Overall, I am exceedingly pleased with the sex performance.

The DLX Classic has a good level of pressure relief. During our tests, I felt no significant level of pressure point build-up. Overall, the mattress is comfortable.

Even so, pressure relief absolutely doesn’t rise to the “excellent” or “outstanding” level. During testing, I couldn’t help but compare this model to the more expensive DLX Premier Hybrid, which earned a notably higher pressure relief score.

The DLX Classic is equipped with 2.25″ of comfort material, which is 1.88″ less comfort material than the average comfort layer thickness of 4.13″, based on all of our tests to date.

That limited comfort layer greatly contributes to the limited pressure relief performance. Even so, at under $1000 for a Queen, this quantity of comfort material is perfectly reasonable.

In our pressure mapping tests, we measured a max PSI of 1.02. A PSI of 2.0 is considered a “high” pressure point and the DLX did a great job in all sleeping positions, remaining well south of that threshold.

When I consider our objective pressure mapping tests, material thickness, material quality, and my subjective experience on the mattress, I’m confident most sleepers will find the pressure relief to be good.

Pressure Map – Side Sleepers

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.16	0.79

Pressure Map – Back Sleepers

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.11	1.02

Pressure Map – Stomach Sleepers

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.12	0.73

Off-gassing on the DLX Classic mattress is strong right out of the box and the odor lasted for 5 days.

Comparing 270+ mattresses tested to date, this off-gassing is 1 day faster than the 6-day average off-gassing period.

DLX mattresses have a 120-night trial period and a lifetime warranty. Shipping is free and returns are also free if the mattress ends up not working out at any point during the trial period.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	8.0	120 nights
Warranty	10%	10	Lifetime
Shipping	5%	10	$0
Returns	20%	10	$0
Trust	50%	8.0	Good
Country of Origin	0%		USA

For reference, the average trial period is 176 nights, 56 nights longer than what is offered by DLX. That being said, the lifetime warranty is longer than average. Among all mattresses tested the average trial is 13 years (excluding 25% of mattresses that offer a lifetime warranty).

The DLX Classic mattress is a flippable mattress, but both sides have the same firmness. Flipping the mattress is simply designed to increase the life of the mattress and not provide a different feel, according to DLX customer support.

If you want to opt for a different firmness, there are three to choose from—soft, medium, and firm. We tested the medium and found the mattress to have a medium-firm feel (6 out of 10 on the firmness scale).

Based on these results, we estimate the soft to be around a 4 out of 10 with a soft feel and the firm to be around an 8 out of 10 with a firm feel.

Support on the DLX Classic is good. During our tests, I felt well supported in all sleeping positions.

The mattress is equipped with a 10.25″ support layer. This is 2.36″ thicker than the average support layer thickness of 7.89″, based on all of our tests to date.

The DLX Classic is unusual in that it’s a flippable mattress. While flippable designs were more popular in the past, today they are fairly rare.

The mattress has a 2.25” comfort layer on both sides of the mattress. However, one of these 2.25” is always acting as a support layer (when it is positioned to be on the bottom). This means the support layers consist of the 8.0” coil unit in addition to the 2.25” comfort layer.

From a purely supportive perspective, this isn’t ideal, as simply having a 2.25” support foam would be better. Notably, the mattress does not contain any reinforced edge support coils or zonal support layers.

All that said, for those who love the flexibility of the flippable design this should be of little consequence. The DLX Classic is available in 3 different firmness levels. This expands the number of body types, sleeping positions, and sleeper preferences that could find the mattress comfortable.

Based on all of my tests to date, an analysis of the materials, and my subjective experiences, I’m confident most sleepers will find support on the DLX Classic is good.

Design

The DLX Classic is a 12.5″ flippable hybrid with a quilted cover on both sides, poly foam comfort layers, and a coil support base. It also comes in a 14″ version, but we personally tested the 12″ version (and found it to be thicker than expected. Our mattress measured 12.5″).

This mattress is available in three firmness levels, making it a good option for sleepers of many sizes and sleeping preferences.

Materials

In total, five material layers make up this flippable hybrid. There are two covers, one on each side, two comfort layers, and a central support unit. The list below details how these layers are stacked:

• 1.5” quilted cover
• 0.75” poly foam
• 8.0” coil unit
• 0.75” poly foam
• 1.5” quilted cover

The Cover

The cover of the DLX Classic is soft and stretchy with a plush feel. It is 1.5″ thick and being a flippable mattress, the DLX has the same cover on both the top and bottom of the mattress.

The Comfort Layer

The comfort layer is a 0.75″ layer of poly foam, regardless of which side of the mattress you’re lying on. Compared to other mattresses we’ve tested this is fairly thin for a comfort layer.

The Support Layer

The support layer is centrally located in the middle of the mattress, with the comfort materials on both the top and bottom. It is an 8.0″ coil support with pocketed coils providing support.

As mentioned above, one layer of the poly foam ends up also serving the role of support, but being that that material is more for comfort, the performance as a support layer is a little lacking.

Product Evolution

The DLX Classic hybrid was originally manufactured and sold from their factory in New York, dating back to around 2014. But in 2023, the DLX Classic went digital and the company began selling the mattress online.

Since its online release, there have been no changes made to the mattress.
