Sleep is so very important to your well-being, yet is constantly ignored. We think that we can bet by with just a few hours of sleep, or worse, fail to invest in a positive sleep environment. If you’ve had enough nights of restless sleep and are in the market for a new mattress, you might be struggling with the Lull vs Purple debate. These two mattresses are both highly rated and offer a wide variety of features. They both use innovative foam mattress technology to better support your body, yet are different in their overall construction. Their price points are both at the higher end of the spectrum, but as they are built to last for at least ten years, you will definitely see a return on your investment. Our aim is to provide enough information so that you can decide who wins in the Purple vs Lull mattress debate.

Quick Comparison

The Lull and Purple mattresses are definitely premium investments. A Lull Queen Size mattress well set you back around $800 while a Purple Queen Size mattress can be found for around $1000. These are not your basic mattresses, though. While older models mainly relied on metal springs for support, both the Purple and the Lull mattresses use foam technology. This leads to an even, supportive place to rest your body after a long day. Both beds are classified as medium firm, so if you’re looking for a fluffier mattress, neither will work for you. Altogether there is a lot to dissect with each mattress, and we hope you continue to read on for all the nitty-gritty information.

  • Slightly lower in price
  • Supportive edge
  • Lighter in weight
  • Thicker
  • Cool foam technology absorbs body heat
  • Natural materials don’t give off odor
  • Extremely quick responsiveness

While the Lull and Purple mattresses are made from foam, their overall construction is quite different.

The Lull mattress has 7 inches of PU foam in its support core, while the Purple mattress only has 4 inches of foam in its support core. As for additional comfort layers, the Lull mattress has 1.5 inches of a foam blend plus 1.5 inches of a gel-infused memory foam. The Purple mattress, on the other hand, has 2 inches of a patented polymer material and 3.5 inches of a high density PU foam.

Both mattresses have a removable and washable cover, which is a nice feature. For the Lull mattress, this cover is made from polyester and rayon, while the Purple cover is made from viscose, polyester, and lycra. All of the materials used allows for a light, breathable feeling when you lay on each mattress.

Comfort

You can get into all the technical specifications of a mattress, but the bottom line is, how comfortable is it? And this is where a bit of personal preference comes into play. Some people cannot bear a lighter mattress, while others love the sensation of being enveloped by a fluffy cloud. Pay attention to the specifications of each mattress and be sure to compare these to your own sleeping experiences.

When we talk about comfort, we mean a lot of important factors. These include firmness, temperature control, and bounce, to name a few. If you share the bed with someone else, then you’ll want to pay attention to the motion transfer of each mattress. Likewise, if you have any mobility issues, then the edge support will be particularly important to understand. There are many ways to measure comfort. These categories are meant to show you what the Lull and Purple mattress have so that you can find the right solution to your sleeping needs.

Firmness and support

Lull vs Purple: Which One Suits You Best?All mattresses are actually given a rating based on their firmness factor. This rating is between soft, at 1-2, to firm, at 8-10. Both the Lull and Purple mattresses have a 6.5 rating, which is classified as medium firm. For most people, this is an ideal feel. The mattresses will be dense enough to fully support your spine, but not too hard so that your muscles feel tight the next day. Again, it’s important to reiterate that there are some people who can only sleep on a soft mattress. If this is the case, you may need to consider an alternative.

While some mattress companies will have different firmness options for mattresses, both the Lull and the Purple come in only one setting. This is because a medium firm mattress has been classified as the best rating for the majority of sleepers. The density of the foam allows for all of your spine to be supported when sleeping on your back. From your tailbone to your neck, each vertebra is cradled so that it stays in its optimal curved position. For side sleepers, a medium firm mattress means that your spine stays straight and protected.

Now, if you are convinced that you need a softer mattress, or even a firmer one, you may need to look at a different product altogether. Foam technology and advanced mattresses will usually fall in the 6 to 8 firmness rating. Luckily, both mattresses offer a 100-day sleep trial. This allows you to properly test out the mattress and learn firsthand if either is for you. Hopefully, you’ll be impressed with it.

Temperature control

When it’s the height of summer, the last thing you need to worry about is a hot mattress. While older spring mattresses retained heat, thankfully newer foam models, like the Lull and Purple, have been created to offer a cooler feeling. The foam in both mattresses has air pockets that allow air to pass through them. Air isn’t trapped which means it won’t warm up inside the mattress. The result is a cool feeling, even when it’s extremely hot out.

The Lull mattress actually uses a special top layer that is made from a gel-infused foam. This layer acts to provide airflow and works to pull body heat away from your body. Not only is it comfortable, but it is scientifically able to provide a cooler sleep for you.

The only downside with cooler foam mattresses is that they can be a bit too cold in the winter months. If you experience a cold winter, you might want to invest in flannel sheets for those winter months. This fabric will provide a better barrier between you and the mattress.

Motion transfer

There’s nothing worse than just falling asleep, only for your partner to shift next to you and disturb your light slumber. Thankfully, the foam technology used in both the Lull and Purple mattresses will greatly minimize any motion transfer.

Lull vs Purple: Which One Suits You Best?

Indeed, Purple boasts of its leading sleep technology that has created special motion isolation bed construction. They pride themselves on the fact that you won’t be able to feel movement from anyone else sleeping in the bed with you. Careful testing went into this technology and the result is astounding.

As for Lull mattresses, the reviews rave about the lack of motion transfer. Multiple users report that no matter how often their partner moves around, they can’t feel it. If you sleep next to someone who is more restless than you, or if you happen to be that person, give your partner a break and try out the Lull.

Responsiveness

The responsiveness in a mattress refers to how quickly it will change its shape when someone lies down on it. While older coil mattresses didn’t ideally respond to an individual’s body, foam mattresses will. Responsiveness is often shown as when you place your hand onto a foam mattress and then lift it off.

What you definitely don’t want with responsiveness is a lasting indent. Purple guarantees that once you shift positions, your mattress will quickly keep up with it. Their biggest comparison is with memory foam mattresses, such as Lull, which will keep an indent for a while. Unless you only sleep in one continuous position, you will want your new mattress to shift with you.

Lull also has a brief responsiveness time, thanks to its sophisticated foam technology. However, Purple seems to be leading in this category. There were some customers who reported having a small indent develop in the middle of their mattress. Unlike older spring mattresses, which should be flipped, advanced foam mattresses should not be flipped. They have specific layers which work best in the order they are placed. However, you should rotate your foam mattress so that the head and foot are reversed. This will help lessen the chances of sinking in the bed, especially if you have two sleepers of varying height and weight.

Resilience and bounce

When it comes to bounce, this refers to how much energy is transferred back to a person. For example, if you drop onto a coil mattress, its large bounce would feel almost like a bit of a trampoline. A foam mattress, however, will have little bounce as the construction works to absorb any impact.

Purple has a great reputation for minimal bounce. Users reported feeling a mixture between being absorbed by the mattress while also being supported. It’s a hard feeling to describe, but once you experience it, you’ll understand. Lull does well with very little bounce effect as well, although it seems to be not quite as firm as a Purple mattress.
Lull vs Purple: Which One Suits You Best?

Resilience and bounce definitely depend on a personal preference. Sleeping, you most likely won’t pay any attention to it. It is important to note that heavier sleepers often report liking mattresses with minimal bounce. The more you weigh, the more this can translate into bounce in older mattresses, which isn’t always a pleasant experience at night.

Edge support

The edge of your mattress might not gather much notice, but if you have any mobility issues, then it’d definitely a feature to be aware of. Basically, if you have more edge support it means that the mattress doesn’t just bend down when you roll off the edge or sit on it.

If you’re worried about falling off a bed, or need a little bit of extra support, then you’ll be happy to learn that the Lull mattress has excellent edge support. Because this mattress has a gel-infused foam top, it essentially has a mattress base. And with this base come firmer walls. You can even see in a picture of the mattress how the edges reach almost to the top and have a firmer structure.

The Purple mattress, on the other hand, has a subtler edge. While it still has a good amount of support, it is not that impressive as offered by the Lull mattress.

Inflation time, off-gassing and smell

Both the Lull and the Purple mattresses are shipped directly to your home. As you can imagine, this would be quite cumbersome if they were shipped as you would use them. However, thanks to innovative packaging, both mattresses are very compactly rolled up and then delivered inside of a box. It is up to you to unroll and basically inflate the mattress.

To begin, it’s worth noting that you will most likely need two people to move the mattress box from your front door to your bedroom. This is especially true if you order a King or California King mattress. The Queen version of the Lull weighs 71 pounds while the Queen version of the Purple is 110 pounds which is quite heavy for a single person, especially a woman, to carry.

Once you have maneuvered the box into your bedroom, now is the time to unbox it. Gently unroll the mattress and place it where you want it to be. You’ll want this to be a flat surface, so either place it on the floor or directly on your bed frame. Once unrolled, it will take 4 to 8 hours to inflate. It can sometimes take even a full day to inflate 100%. If you set up your new mattress at night, you might want to consider sleeping in a different room, so as to allow the mattress enough time.

Both the Lull and the Purple mattresses will be wrapped in plastic, which can give off a strong odor. This can take two to three days to dissipate. Again, if you are sensitive to smells, you might want to give your mattress some space before using it.

What is really nice about the Purple mattress is that it is made from non-toxic, food-grade materials. This means that there should be no chemical smell coming from the mattress itself. The Lull should be fine as well, although there have been a few comments about the odor. Generally, though, after three days both mattresses should have no residual smell.

*out of 10

When you sleep on your back you want your spine to naturally curve and be supported at all points. When you sleep on your side, you want your spine to be aligned straight. While stomach sleeping isn’t usually recommended, there are many people who find it comfortable, or who instinctively change to this position in their sleep.

Both the Lull and the Purple mattress do a great job of providing adequate support for all sleeping positions. As you can see from the chart, the Lull provides slightly better support for back and stomach sleepers.

While sleep position should be taken into account, most people constantly shift around in their sleep. Add in a partner and their sleep positions, and it quickly becomes difficult to narrow down your sleep chart to just one position.

Sizes and pricing

SIZE Lull Purple
Twin $500
Twin XL $550 $699
Full $700 $899
Queen $800 $999
King $900 $1,299
California King $900 $1,299

Lull mattresses are less expensive than Purple ones. Whether this price is justified largely depends on what you are looking for in a mattress. The nice thing about both is that there are multiple size options for each product. However, the Purple mattress, unfortunately, does not come in a Twin size.

Purchasing anything online can be a daunting experience. A mattress is especially so. Most people like to go to a mattress store and physically try out their options. When you add in the high price tag of advanced technology mattresses, it can be doubly intimidating to buy something you’ve never even felt.

But if you had to choose between lying on a mattress in a store for a few minutes versus sleeping on a mattress for 100 days, which trial is better? Online vendors understand the trepidation there is about such purchases, which is why both Lull and Purple have a 100 sleep trial period. You can wear your favorite pajamas, get comfortable, and really test out your new mattress. Both offer no hassle return policies. After 100 days, you should know without a doubt if the mattress will work for you.
Lull vs Purple: Which One Suits You Best?
One important note for both mattresses is that it can take quite a few days to get used to the foam material. If you’re transitioning from a traditional spring mattress, or even a pocket coil mattress, the first night on a foam bed can make it seem like your back is broken. This is not an exaggeration. Your body will have become accustomed to large pressure points from an older mattress and the absence of these pressure points takes some getting used to.

While some new users report nothing out of the ordinary, quite a few people are alarmed after their first night. The biggest takeaway is that this is normal. Keep sleeping and within two to three nights your body will be able to adjust and you can better reap the benefits of a foam mattress.

If you decide to keep either your Lull or Purple mattress, you will then have a ten-year warranty attached to it. This warranty guarantees a full refund for either mattress. This is very impressive. Most people like to get a new mattress every ten years, and it’s nice when a warranty lasts the natural life span of a product.

As for customer service, both companies come highly rated. If there are issues, or you need to return it within the 100-day window, just contact either company and they will be happy to help. Keep in mind that the Lull mattress only has delivery for the US. Purple, on the other hand, will deliver to both the US and Canada. So before you get your hopes up, Canadians, be aware of this delivery policy.
