Lull vs. Purple Mattress Overview

Purple is known as a powerhouse in the bed-in-a-box industry because of its unique feel, and Lull offers a more traditional mattress for people who aren’t sure the uniqueness of Purple is right for them. Here are the primary points of differentiation between these beds:

  • Feel — The Lull mattress has a soft, neutral-foam feel, while the Original Purple mattress has a unique gel-like feel thanks to its proprietary Hyper-Elastic Polymer top layer.
  • Price — The Lull mattress is considerably more affordable than the Original Purple mattress after taking into consideration discounts and promo codes.
  • Temperature regulation — The Purple mattress allows for a lot more airflow than the Lull mattress, thanks to Purple’s design and special top layer.
  • More Options — Lull offers only one model, while Purple offers four models. We primarily focus on the Original Purple mattress in this article.

Design & Construction

First up, let’s look at Lull and how the company’s flagship mattress is constructed. Lull is not new to the bed-in-a-box concept. The company was one of the early entrants in the space and is headquartered in Santa Barbara, California.

The Lull mattress has three foam layers and totals 10″ thick:

  • Base layer – 7” foam base layer for support
  • Transition layer – 1.5” of a proprietary blend of foams, which for this review we’re simply calling neutral-foam, and it limits the stuck-in-the-mud feeling you would otherwise get with the top layer
  • Comfort layer – 1.5” memory foam top layer

With that in mind, let’s explore Lull compared to Purple in terms of mattress design and construction.

Purple offers four mattress models, including the Original Purple, the Purple Hybrid, Purple Hybrid Premier 3 and Purple Hybrid Premier 4. We’ll focus on the Original Purple in this review, but you can also check out our full Purple mattress comparison.

The Original Purple has three layers:

  • Support layer — 4″ layer of dense support foam
  • Transition layer — 3.25″ layer of 1.8-pound polyurethane foam to neutralize or soften up the feel of the dense neutral-foam below
  • Comfort layer — 2″ layer of the brand’s patented Hyper-Elastic Polymer

Feel & Firmness

When you’re shopping for a new mattress, two of the most important considerations are feel and firmness. Here’s how we reviewed Purple vs. Lull in these categories.

We rate Lull as a medium on our firmness scale. It isn’t too soft or hard, and it has plenty of support and pressure relief for all types of people.

The mattress doesn’t have a prototypical memory foam feel. You can tell that it is memory foam you’re laying on, but the top layer doesn’t hug or conform to your body’s shape the way you’d expect.

Soft, neutral-foam feel that is very accommodating

Beds with a neutral-foam feel tend to be a little less divisive than beds that have a typical memory foam feel. Overall, all of the team members here at the Slumber Yard found the Lull mattress to be accommodating and comfortable.

In contrast, Purple mattress uses a patented material called Hyper-Elastic Polymer, which gives the bed a particular feel. It feels and functions more like silicone or gel, which is why we describe the bed as having a gel-like feel. As you lay down on the bed, you can feel the polymer shifting, adjusting and folding under your body.

Since Purple is made from such a unique material, it’s difficult to give a firmness rating. However, we’d say it’s closest to a medium on the soft-to-firm scale.

Not everyone is going to love the feel of the bed. It’s different from the typical foam mattress. However, most people enjoy the feel of the Hyper-Elastic after they get used to it.

The other nice thing about Hyper-Elastic Polymer is that it’s extremely responsive. It snaps back to position almost immediately after pressure is released off the bed.
You’ll need to try out both beds to decide if you prefer the Lull mattress vs. Purple since the latter brand has a one-of-a-kind feeling. However, we see the Lull mattress as the safe pick between Lull vs. Purple as far as the feel goes. In other words, if you don’t want to rock the boat, Lull is the ticket.

Other Factors to Consider

Couples will want to pay close attention to edge support, temperature regulation and motion isolation when they’re choosing between a Lull vs. Purple mattress.

Edge Support

Lull’s edge support isn’t the best we’ve seen. If you don’t like to cuddle, you may want to go with a larger size. Purple has pretty decent edge support (it’s better than Lull’s), but it isn’t our top pick in this category.

Motion Isolation

With both Lull and Purple, you aren’t likely to notice your partner moving around at night unless you’re a particularly light sleeper. Both mattresses passed our motion transfer tests easily.


Lull is a temperature-neutral bed, so it won’t heat you up or cool you down significantly. This is a plus for hot sleepers who like the feel of memory foam since the material is typically known for trapping heat. 

Purple’s Hyper-Elastic Polymer lets you sleep on the cooler side of the spectrum because it’s a temperature-neutral material. Plus, the top layer is in a grid formation, creating tons of tiny squares. This design allows for a good amount of airflow near the top of the bed.
All in all, we have to give the edge to Purple in terms of temperature regulation. If you’re a hot sleeper, Purple is the better option, plain and simple. We even included Purple on our list of the Best Beds For Hot Sleepers.

Body Type Analysis

  • Petite

    If you weigh less than 230 lbs, most foam mattresses should work for you. Lull or Purple should be fine if you’re in this weight group. With that said, mattresses will likely feel firmer than they’re rated since your body places less pressure on them than a heavier person would.

  • Normal

    When compared to other body types, average-sized individuals should have the easiest time finding a comfortable mattress. We think that both Purple and Lull can accommodate these folks.

  • Heavy

    We wouldn’t suggest either Purple or Lull for individuals who weigh over 230 pounds. Instead, go with a Purple hybrid bed or another mattress with coils for increased durability and the support you need.

Sleeper Type Analysis

  • Side Sleepers

    Lull is better for side sleeping than any other position. Purple is also great if you sleep in this position and even made our list of best mattresses for side sleepers.

  • Combo Sleepers

    Both Lull and Purple will suit combination sleepers, providing enough pressure relief for when you’re sleeping on your side and enough support for when you’re on your back or stomach.

  • Back & Stomach Sleepers

    The more petite you are, the more Lull will be suited for back and stomach sleepers. We also like Purple for these individuals since it offers enough support and helps keep your spine aligned.
