How is the Premier 4 Different?

The Purple Hybrid Premier 4 has a higher performance score than average, but also a higher price tag—over 50% more than the average specialty mattress and 2.5 times the cost of the average hybrid mattress.

Advantages

The cooling is better than average with a practically perfect performance. Motion transfer is less and response is faster. Additionally, sex performance is above average largely thanks to the bouncy Purple Grid.

Neutral Factors

The Premier 4 has deeper than average sinkage but higher than average bounce.

Disadvantages

The only area where the Purple struggles is in edge support where it has poorer support than the average mattress.

Cooling was exceptionally good on the Purple Hybrid Premier 4. In our objective tests, we measured a maximum surface level temperature of 87.6°F.

• 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

This is tied for the 2nd coolest mattress we have tested to date (tied with the Purple Hybrid). It was 3.4° cooler than the average max surface level temperature among all mattresses we’ve tested to date (which is 91.0°F).

Heat dissipation was insanely good. Within 1 minute after we got off the mattress the temperature had dropped to 83.6°F, a decrease of 4.0°.

By the 2-minute mark, it hit 82.6°, and then stayed around that temperature. That indicates that the Purple Hybrid Premier is able to dissipate nearly all of the retained heat within 1-2 minutes.

This rapid heat dissipation curve is significantly better than the average. Most mattresses will see continued heat dissipation through the 5-minute mark, but even then, retain a more notable level of heat.

Heat Dissipation Over Time

My subjective experience on the mattress mirrored what we saw in the data. I felt cool throughout our test. Purple hyper-elastic polymer does most of the heavy lifting, but it’s also aided by the foundational layer of coils.

These materials both don’t retain much heat and also have an incredible level of airflow. These factors combine to allow the Purple Hybrid Premier 4 mattress to be the 2nd coolest mattress we’ve tested to date. 

The Purple Hybrid Premier 4 has deep sinkage. In our pressure point test, we measured a total sinkage depth of 2.54”. This is moderately deeper than the average across all mattresses we’ve tested, which is 2.16”. With 4” of Purple’s hyper-elastic polymer on top it makes sense.

The level of sinkage is documented in the image below.

The Purple material easily gives way where body weight is applied, relieving pressure and creating contour. While the sinkage depth is a bit deeper than average, it’s still within a range that most sleepers will find comfortable.

Purple’s Premier Hybrid is available with 3” and 4” of hyper-elastic polymer material on the top layer. Either option will be suitably comfortable for most sleepers. You can read our Purple Hybrid Premier 3 review here.

However, the Purple Hybrid Premier 4 does have a little more sinkage, which is likely to yield better pressure relief (especially for heavier weight and side sleepers).

In our tests of the Purple Hybrid Premier 3 mattress, we measured a sinkage depth of 2.21”.

Motion transfer on the Premier 4 was extremely low. In our accelerometer tests, we measured an acceleration range of 4.55 m/s².

This is notably better than the average across all mattresses we’ve tested to date, which is 5.84 m/s².

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

While the total acceleration range is low, motion does linger on the mattress for longer than many others. This is simply due to the Purple hyper-elastic polymer grid.

The material itself and grid design are highly susceptible to motion, motion that can then be transferred around the mattress.

In our motion transfer chart, you can see that there is a higher level of energy up until 0.5 seconds, while moderate energy persists until 1.0 seconds.

If you are easily disturbed by motion you may find the Purple material is a little too sensitive for you.

Hybrid vs. Foam

All-foam mattresses tend to keep motion transfer lower, with beds like Leesa’s Original (2.06 m/s²), Nectar’s Premier (2.8 m/s²), and BedinaBox’s Original (2.85 m/s²) dissipating motion more quickly and keeping acceleration to a minimum.

Response time on the Purple Hybrid Premier 4 mattress was lightning fast. Within 0.2 seconds most of the materials have recovered and by 0.3 seconds the remaining materials have rebounded to their original shape.

The level of responsiveness is documented in the video below.

The response time was incredibly fast. The Purple Hybrid Premier 4 mattress is able to mostly recover within 0.2 seconds and a full recovery is achieved by 0.3 seconds.

This is tied for the fastest response time we’ve tested to date (tied with 3 other Purple mattress models, in addition to Ghostbed Luxe, Winkbed, & and a handful of others).

If you want the absolute fastest response time so that you never feel stuck and can easily move, this is it.

Total bounce on the Purple Hybrid Premier 4 mattress is extremely high. In our bounce test, we measured a total bounce height of 14.33”.

This isn’t the absolute highest we’ve measured to date, but it’s fairly close. On average (across all mattresses we’ve tested to date), we see a total bounce height of 9.29”.

Having a little extra bounce can be beneficial for sex (more info below).

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

Edge support on the Purple Hybrid Premier 4 is good, but not amazing…at least not while sitting.

While sitting directly on the edge of the mattress we measured a maximum compression of 4.75”.

This is definitely on the high end of what I like to see. On average, we see a maximum compression of 4.82”.

Though in this case, being average isn’t really ideal. That said, I think we’re seeing more edge compression due to the easily compressed nature of the top layer of hyper-elastic Purple polymer.

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

Since the material gives way so easily, there just isn’t much push back in that top 4.0” of material. Once you do sink through the first 4.75” the mattress does feel supportive. In addition, since the total profile of the mattress is a bit thicker that helps as well.

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

While sitting edge support leaves something to be desired, support while lying directly on the edge of the mattress felt great.

The Purple Hybrid Premier 4 uses a foam edge support encasement system.

This helps the edges feel strong and supportive, which I can attest to. While lying on the absolute edge of the mattress it feels every bit as supportive as it does while in the middle.

The best mattresses for sex have high bounce, good edge support, quiet materials, and good pressure relief and cooling.

These 5 factors make up the NapLab sex performance score.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	10	Extremely High
Edge Support	20%	7.8	Fair
Noise	5%	8.0	Moderate
Pressure Relief	5%	10	Outstanding
Cooling	5%	10	Outstanding

This is an excellent score and based on the individual factors that make good sex, it’s easy to see why the Purple is a clear winner. Let’s talk through some of the factors.

First off, bounce. Bounce is hugely important for good sex and helps to create an active and engaging surface. The Purple Premier has no shortage of bounce and scored great marks here.

Pressure relief and cooling were also exceptionally good. Again, I think we have the Purple grid to thank here. The 4.0″ grid is the thickest hyper-elastic layer that Purple offers. That extra material really helps avoid pressure points when getting frisky.

Edge support was good, but not great. Thank being said, not everyone cares a lot about edge support. If edge support is critically important to you, you may want to consider the Purple Premier 3, which had 0.5″ of less sinkage on the edge, but it’s not a huge difference.

Pressure relief is exceptionally good on the Purple Hybrid Premier 4 mattress.

The 5.0” of comfort material on top easily compresses and contours to the body, while the support foam and pocketed coils create appropriate support for a wide variety of body types.

The feel of the mattress is just fantastic. It does an amazing job at helping to alleviate pressure points in all sleeping positions. 

Initially, after unboxing the mattress there was a strong smell. The smell lingers for 4 days, after which there isn’t much smell.

Most mattresses we’ve tested to date smell for 2-4 days. The average duration is 2.72 days.

The company score takes a look at factors that may influence your experience with the mattress.

Factors include length of the trial period, warranty, shipping / return costs, and country of origin.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	8.0	100 nights
Warranty	10%	8.0	10 years
Shipping	5%	10	$0
Returns	20%	10	$0
Trust	50%	8.0	Good
Country of Origin	0%		USA

Purple mattress has a good history of fair and consumer-friendly policies and terms—no alarming red flags to note.

They have a pretty standard 100-night trial period with a 10-year warranty. Shipping is free, returns are free. There’s not much to complain about.

Comparing all mattresses tested to date, this trial is 56% shorter and the warranty is 3 years shorter.

All of their mattresses are made in Utah at different factories.

A couple of policies to note which may or may not be important to you include:

1. 21-Night Break-In Period: This is a required time frame after you receive the mattress where you cannot initiate a return. This give your mattress time to fully expand as well as giving your body time to get used to the mattress. This is pretty standard in the mattress industry. If after the first 3 weeks you still don’t like it, you can request a return between day 21-100 for a full refund.
2. No Max Sleeper Weight: While Purple technically states that their mattress can support up to 600 lbs. (or 300 lbs. per side), they also say that too much weight on the mattress cannot void the 10-year warranty.

If you have questions about the mattress before purchase or questions after your mattress has been delivered, Purple does provide a Live Chat feature where you can talk to a real representative.

From my experience, the service was a bit spotty. One question took over 20 minutes to be answered while a follow-up question took only 3-5 minutes. This was with two different representatives.

While live support may not be an important factor to you, it feels like it’s worth mentioning.

The Purple Hybrid Premier 4 comes in around a 6 out of 10 on the firmness scale, where 10 is the most firm.

Despite having a thicker Purple grid, this is about the same firmness as the Purple Hybrid Premier 3.

• For something a touch softer, consider the Original Purple (no coils) — 5 out of 10.
• For something a touch firmer, consider the Purple Hybrid — 6.5 out of 10.

Being a 6 out of 10, the Purple Hybrid Premier 4 would be suitable for a wide range of sleepers, regardless of weight or sleeping position.

We have a table, shown below, that we use to help sleepers decide if a mattress is right for them. As you can see, the Hybrid Premier 4 has widespread appeal across the sleeper spectrum.

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	Yes	Yes
150-250 lbs.	Yes	Yes	Yes
250-300 lbs.	Yes	Yes	Yes

Design

The Purple Hybrid Premier 4 is a 13″ thick mattress that uses a combination of materials including foam, pocketed coils, and the patented Purple grid system (a hyper elastic polymer) to create something unique.

The Premier 4 has the thickest Purple grid among any Purple mattress to date, it’s 4″ thick.

The grid works with the other materials for maximum cooling, airflow, pressure relief, and comfort.

Materials

The Purple Hybrid Premier 4 is a specialty hybrid mattress that is 13.5″ tall and made of 4 different layers. Here is a complete breakdown of all of the materials from top to bottom:

• 4.0″ elastic polymer (Purple Grid)
• 1.0″ poly foam
• 7.5″ pcoketed coils
• 1.0″ poly foam (support foam)

The Cover

The cover of the Purple Hybrid Premier 4 is a textile blend of polyester (67%), Viscose (29%), and Lycra (all +/- 5%). It is lightweight and soft, while also being breathable enough to allow the thick grid below to have maximum effect.

Aesthetically, the cover is mostly white with a gray base and short diagonal gray lines on the top.

The Comfort Layer

The comfort layer on the Purple Hybrid Premier 4 contains the 4.0″ thick layer of Purple grid followed by a 1.0″ layer of poly foam.

On the edges, there is a thick foam layer for improved edge support and to help contain the grid. This top layer of foam (purple) is 4.0″ thick and is followed by a thinner layer of poly foam (orange).

The thinner poly foam acts as a transitional layer material to separate the grid from the pocketed coils below. This layer plays an important role in the comfort and overall support of the Premier 4.

Without this layer of poly foam, sleepers would be more likely to experience pressure points.

The poly foam combined with the thicker grid and edge foam creates a 5.0″ thick layer of comfort material which should be more than sufficient for a wide range of sleepers, regardless of weight or preferred sleeping position.

The Support Layer

The support layer below the Purple grid consists of 7.5″ high coils that are individually pocketed for pressure point relief and limited motion transfer.

Pocketing these coils also helps to limit sound from the coils as you move around the mattress.

In general, hybrids are known to have great airflow, bounce, and fast response time. The coils play a huge role in the success of these factors.

Lastly, below the coils is a final 1.0″ layer of poly foam. This foam is a high-density foam that supports the upper layers of the mattress.

Product Evolution

The Purple mattress launched in 2015, using a Kickstarter campaign as the catalyst into production. The campaign raised a little over $170,000 and with only 320 backers, they were off the ground.

The Original Purple mattress is a 10″ thick option that uses their patented Purple grid combined with a poly foam.

Today, the Original Purple is still for sale as well as 3 hybrid options and an option for plus-sized sleepers.

The complete Purple lineup includes:

• Original Purple
• Purple Hybrid
• Purple Hybrid Premier 3
• Purple Hybrid Premier 4
• Purple Plus

The Hybrid, Hybrid Premier 3, and Hybrid Premier 4 were all iterative improvements over the original Purple mattress. Looking in terms of evolutionary improvement over time, Purple is moving towards a hybrid design future.

While the Purple Hybrid Premier 4 has not had any major updates to that model specifically since it launched, it ultimately is the culmination of years of testing and feedback from sleepers. A thicker layer of Purple grid material and pocketed coil base both help to alleviate common issues with the original Purple.
