Purple and Lull are both foam beds that share several characteristics but are also distinctly unique. In this article, we’re breaking down who should buy the Purple mattress and who should buy the Lull.
The Lull Mattress is a simple design with several layers of memory foam, while the Purple uses foam and a squishy grid layer. The Purple will feel unique and pressure-relieving, and the Lull will feel like a traditional memory foam that you may be used to if you currently have a foam mattress. If you tend to sleep hot or sleep with a partner, you may enjoy the feel of the Purple. But the Lull is a great mattress for back sleepers looking for a neutral foam feeling.

A mattress’s firmness level refers to where it falls on the firmness scale of 1 to 10, with 1 being very soft and 10 being very firm. It’s important to understand the firmness level that you prefer and that works best for your body type and sleeping position, and having this in mind while mattress shopping can greatly narrow the overwhelming number of choices that many mattress shoppers face. It’s also important to consider a mattress’s feel, as two beds that share a similar firmness level, like the Purple and the Lull, can feel very different to the touch.
Both the Purple and the Lull are medium-firm mattresses, which means they can appeal to a wide variety of sleepers. They’re firm enough to offer support for all three sleeping positions yet soft enough to accommodate sleepers who like a plush feel. The Purple is slightly more firm than the Lull (their firmness levels are 7/10 and 6.5/10, respectively), and, as we’ve mentioned, they feel completely different.
Both beds support sleepers in the lightweight to average-weight categories in all sleeping positions, so the firmness and feel that work best for you will ultimately come down to preference. If you like a unique sleeping surface that’s both responsive and conforming and the idea of “floating” on the mattress sounds intriguing to you, try the Purple. If you want to play it safe, we recommend the Lull for its accommodating, soft foam feel.
Motion isolation is an important consideration for couples and individuals who sleep with a pet or a child. Put simply, motion isolation refers to how little motion transfer is felt throughout the mattress when pressure is applied or removed. The less movement is felt, the better the bed’s motion isolation.
Motion isolation varies from mattress to mattress, but some mattress styles tend to excel in this performance category more than others due to the characteristics of their materials. All-foam beds, for example, absorb motion better than hybrid mattresses, which feature coils and tend to naturally have more bounce. Both the Lull and the Purple Original isolate motion very well, making them appealing for those who are easily disturbed by the motions of a partner, pet, or child throughout the night.
Edge support is how much a mattress sinks at its edges when pressure is applied. In general, all-foam beds tend to have poor edge support while innerspring and hybrid mattresses perform better in this category.
Edge support should be a priority in your mattress shopping journey if you tend to sleep on the edges of a mattress, like to sit on your bed for an extended period of time (for instance, to tie your shoes or check emails) or have trouble getting in and out of the bed. Both the Lull and the Purple have less-than-stellar edge support, but this doesn’t mean the companies ignored this quality; it’s somewhat par for the course with all-foam mattresses.
A bed’s pressure relief refers to how well it alleviates aches and pains that arise from pressure points or that already exist as a result of an individual’s lifestyle or health condition. All sleeping positions have pressure points, and a mattress’s ability to alleviate any pain that arises from these areas depends most on the comfort layers of the mattress. If you are waking up in pain, see the best mattresses for back pain.
The Lull does a nice job relieving pressure in all three sleeping positions thanks to the dual comfort layers that provide a nice hug. The Purple also provides pressure relief through the Purple grid in all three sleeping positions.

A spine that is properly aligned throughout the night will be encouraged to maintain its natural “S” curve. Spinal alignment is essential to all sleepers regardless of size, age, sleeping position, or weight. When sleepers don’t achieve adequate spinal alignment on their mattress, they can experience aches, pains, and, sometimes, long-term health issues. Understanding mattress firmness levels and mattress characteristics will best help you to achieve proper alignment.
On the Purple, lightweight and average-weight sleepers should find that they have adequate cushioning in the side sleeping position to keep the spine aligned, and back and stomach sleepers shouldn’t sink too much into the mattress. On the Lull, average-weight side sleepers will sink nicely into the dual-foam layers, allowing the spine to align. The best mattress for stomach sleepers will provide proper spinal alignment and depend on the sleeper’s weight, but we don’t think the Purple or the Lull is firm enough to properly support most stomach sleepers.
The average mattress lifespan is seven years. Even though neither the Purple nor the Lull are outrageously expensive, it’s important to make sure your investment will last you for a long time. Durability is correlated with edge support and sagging, and one thing can lead to another in a poorly constructed mattress. The Purple and the Lull both feature quality materials, and we haven’t seen any customer reviews about below-average longevity for either of these mattresses.
Those who tend to sleep hot can suffer from night sweats, discomfort, and poor sleep as a result. The Lull sleeps temperature-neutral, which is on par with other well-made foam beds on the market. If you sleep hot and are looking for a cool night’s sleep, however, we can’t recommend the Purple enough. The top layer of hyper-elastic polymer has an open, grid-like structure that lets air flow beneath you as you sleep. This is great for warm climates and individuals who tend to sleep hot. For similar options, see the best mattresses for hot sleepers.
The Purple has an innovative construction that gives the mattress its unique feel. It has a polyester, viscose, and spandex blend cover that’s stretchy and pairs nicely with the bed’s responsive design. But the top layer of the mattress is where Purple stands out from the crowd.
It consists of 2” of Purple’s hyper-elastic polymer in a column grid pattern. This material is virtually silent, has soft bounce, and compresses only where pressure is applied, creating the floating feeling that Purple’s mattresses are known for. This is followed by a 3.5” transitional layer of high-density polyfoam, which prevents sleepers from sinking into the firm base layer.
The support layer is 4” of high-density polyfoam that stabilizes the entire bed. Altogether, the Purple’s layers measure just 9.25” tall, making it shorter than the average foam mattress.
The Lull is a medium-firm memory foam mattress (6.5/10) that’s 10” thick and consists of a cover and three foam layers. The cover is made from polyester and rayon, and the comfort layer features 1.5” of gel-infused memory foam that promotes cooling by absorbing and distributing body heat.
This comfort foam also relieves pressure points for sleepers in most positions. This is followed by a 1.5” transition layer that isolates motion, dulls the traditional memory foam deep-sinking sensation, and offers full-body support. The bottom layer of the mattress is a 7” polyurethane foam foundation that provides durability and added support while preventing sagging.

The Purple Original mattress ships free to all 50 states and anywhere in Canada. It comes delivered to your door as a bed-in-a-box mattress (or, in Purple’s case, a “bed-in-a-bag” mattress). You’ll need to release the Purple from its bag and unroll it onto your bed frame. After that, you have 100 nights to try out the Purple. And Purple’s 10-year warranty offers shoppers extra peace of mind.
See: Purple Mattress Return Policy
The Lull mattress ships for free to states in the contiguous U.S. The Lull ships as a bed-in-a-box, which means the mattress arrives at your doorstep compressed and rolled up in a box. Lull offers a 100-night return policy, which is typical compared to other online mattress brands. You can receive a full refund during this trial period if you decide to return the mattress. What’s more, Lull offers a 10-year warranty for the mattress.
Purple paired its proprietary Purple Grid with individually wrapped coils to create this even-more-breathable hybrid mattress. It’s also more supportive than the Original, making it a better pick for heavyweight or back and stomach sleepers.

Purple’s luxury option, the Purple Hybrid Premier comes with 3” or 4” of the Purple Grid and a responsive pocketed coil layer.
See our full Purple Hybrid Premier mattress review for more details.
There’s no clear winner when the Lull and the Purple are put head to head, as each bed has unique qualities and areas where it may fall short for some folks. Both are quality mattresses for the price and share similar policies, firmness levels, and retail price points, so the right mattress for you will come down to feel.
We recommend the Purple mattress for shoppers who like the idea of floating on the mattress and who sleep hot. If you’re playing it safe and want a neutral foam bed that’s going to provide some contouring in any sleeping position, opt for the Lull. If you’ve been looking into the Purple and the Lull while considering a new mattress, we hope this mattress comparison was helpful as you make your decision.
