Lull vs Purple Mattress Review

If you’re looking for a quality mattress, chances are you’ve come across the Purple and Lull websites. Both of these well-known online mattress brands offer comfortable beds that ship conveniently to your door.

The Lull and Purple mattresses have quite a few differences, so it might be difficult to choose between the two. Though they’re both considered foam beds, the Purple mattress’s Hyper – Elastic polymer grid layer feels very different from the Lull’s memory foam top layer.

To help you decide which of these beds is best for you, I’ll go over their construction, feel, and features in this mattress comparison. Don’t have time to read the entire review? Skip to my review summary below.

Similarities

These two mattresses are best for very different sleepers. Before we get into the differences between the Lull and the Purple mattresses, let’s talk about their similarities.

  • Both of these mattresses are great fits for back sleepers. These beds combine support and pressure relief for a balanced feel, which is great for back sleepers who need gentle support at the lower back.
  • The Purple and the Lull are both bed-in-a-box mattresses that use foam support layers. Though the Purple uses a hyper elastic polymer in its comfort layer, its polyurethane foam layers are very similar to the Lull’s. So both mattresses will offer comparable support.

What Are These Mattresses Made Of?

Now that we’ve discussed their similarities, let’s talk about what makes these mattresses unique. First, let’s take a look at each bed’s construction so you can see how their designs differ. I’d also encourage you to read the full Lull mattress review and full Purple mattress review for a more in-depth look at each bed.

Lull

Cover — The Lull is covered in a durable polyester blend. It should feel nice and soft to the touch.

Comfort Layer — The Lull’s comfort layer is made of 1.5 inches of gel-infused memory foam. It has a slow response to pressure and offers sleepers body-contouring. This gel memory foam layer means the Lull sleeps cooler than a traditional memory foam bed, which is a nice perk for hot sleepers.

Transition Layer — The Lull’s transition layer is made of responsive poly foam, which helps balance out the sinkage provided by its memory foam comfort layer. This layer will help ease you down onto the support layer of the mattress.

Base Layer — The Lull’s base layer is made of high-density poly foam, a firm foam that offers support to the rest of the bed.

Purple

Cover — The Purple is covered in SoftFlex fabric, which is a blend of polyester, viscose, and lycra. It’s stretchy and breathable, which is great for promoting airflow.

Comfort Layer — The Purple’s comfort layer is made of a proprietary hyper-elastic polymer. This unique, rubber-like material is set up in a grid structure. The walls of the grid flex underneath pressure points to offer relief, but stay supportive everywhere else. Sleepers tend to either love or hate the grid, so if you’re looking for a traditional feel, you might want to stick with the Lull. But if you’re a combination sleeper, this unique layer should keep you comfortable and supported in any position.

Transition Layer — The Purple’s transition layer is made of high-density poly foam. It’s very responsive, so you should have an easy time moving around on this mattress.

Base Layer — The base layer is made of firm high-density poly foam that offers support to the rest of the mattress.

Lull vs Purple

So what exactly do these different constructions mean for you? Well, the Lull will feel softer and offer more sinkage than the Purple thanks to its memory foam comfort layer, while the Purple’s hyper elastic polymer makeup will feel bouncier and offer less sinkage.

If you’re a side sleeper, you’ll probably prefer the soft pressure relief the Lull mattress offers. The Purple’s grid system could be just a touch too firm for strict side sleepers. If you’re a combination sleeper, you may prefer the responsiveness of the Purple. Combo sleepers might feel stuck in the memory foam top layer of the Lull and struggle to change positions at night.

Lull Mattress Side Sleeping
I like the Lull for side sleepers.

Back sleepers looking for a more traditional feeling mattress might want to stick to the Lull. The Purple could appeal to back sleepers who want to feel more on top of their mattress rather than in it.

Hot sleepers might prefer the Purple mattress. Its hyper-elastic polymer comfort layer promotes airflow and is a bit more breathable than the Lull’s memory foam comfort layer. The Lull will still sleep cooler than a traditional memory foam mattress, but if you’re really concerned about overheating at night, I’d recommend avoiding an all-foam mattress like the Lull.

Purple Corner
The Purple mattress sleeps nice and cool.

Because both of these beds rely on foam support layers, stomach sleepers and heavier sleepers might want to look at other mattresses. Innerspring or hybrid mattresses that offer stronger coil support are normally better fits for these folks. I’d recommend checking out the best mattress for stomach sleepers or best mattress for heavy people roundups to find a better fit.

What Do These Mattresses Feel Like?

Now you know what these beds are made of and who they could work best for, but what exactly do they feel like? I’ll describe the feel of these mattresses below.

Remember, feel and firmness are subjective. Sleepers will experience firmness differently depending on their body types and preferred sleeping positions. For reference, I’m 5’10”, 125 lbs, and prefer to sleep on my side.

Lull

I rated the Lull as a 6 out of 10 on the firmness scale. The industry standard for a medium firmness level is a 6.5, so the Lull is a medium soft mattress. This medium soft feel makes the Lull a good fit for side and back sleepers. It will offer side sleepers pressure relief at the shoulders and hips, which helps prevent stiffness. The Lull should also offer back sleepers some nice body contouring while keeping their hips up in line with their shoulders.

Strict stomach sleepers will likely need a bed with firmer support. Their hips will probably sink too far into the Lull, throwing their spines out of alignment and leading to back pain. Stomach sleepers may want to check out our best firm mattress options.

The Lull is not particularly bouncy thanks to its motion-absorbing memory foam layer. It does an average job isolating motion, which means that you won’t be disturbed by a partner tossing and turning, but you would be disturbed if a child or pet jumped on your bed.

Purple

I rated the Purple mattress as a 7 out of 10 on the firmness scale, so it’s a touch firmer than a medium firm mattress. I’d say this makes the Purple a good fit for back sleepers who like a firmer feel. My spine felt well-aligned when I was on the Purple, and I felt a nice combination of pressure relief and support.

The Purple should also feel comfortable to combination sleepers, no matter which sleeping positions they cycle between. The Purple is very responsive, so you won’t have trouble changing positions at night. And its grid system should offer enough support and pressure relief for all sleeping positions.

However, if you’re a strict side or stomach sleeper, more than a few hours on the Purple without a position change could lead to pain or stiffness. These sleepers should opt for a different mattress; side sleepers will be happier on the softer Lull, while stomach sleepers will need a firmer bed.

Like the Lull, the Purple did an average job isolating motion so couples could be happy on this mattress as well. The Purple’s comfort layer is reinforced with poly foam to offer some additional edge support, which is an extra perk for couples who want to spread out on their entire sleeping surface.

I do think the Purple sleeps a bit cooler than the Lull, so hot sleepers or couples who overheat may prefer this mattress. If you sleep hot, you can also check out some of the year’s best cooling mattresses for more options.

Other Models

Purple does offer additional mattress models. Keep reading below to see how they compare to the Lull and the original Purple mattress.

Purple

  • The Purple Hybrid mattress features an innerspring coil support system, and is sturdier than the original Purple and the Lull mattress. It has a firmer feel than both these mattresses, so I’d advise stomach sleepers interested in a Purple mattress to check out the Hybrid.
  • The Purple Hybrid Premier is very similar to the Purple Hybrid. This mattress is bouncier than the original Purple and the Lull, so combo sleepers willing to spend a little extra might want to check it out. The Hybrid Premier is the softest Purple mattress, so side sleepers who don’t like the memory foam feel of the Lull might want to take a look at the Hybrid Premier.

Which is Better: Lull vs Purple

So, which mattress should you buy? Take a look below to see some quick facts on who each of these mattresses is best for.

Lull Pros

  • Back sleepers looking for a more traditional-feeling bed-in-a-box might like the mix of pressure relief and spinal support the Lull offers.
  • Side sleepers who need pressure relief at the shoulders and hips should find what they’re looking for in the Lull.
  • Memory foam lovers will enjoy the body-contouring feel of the Lull, and its cooling gel infusion is a nice perk for memory foam lovers who sleep hot.

Purple Pros

  • Back sleepers who like a firmer feel should like the Purple. It offers gentle support that should help them achieve a neutral spinal alignment.
  • Combination sleepers will really enjoy the bouncy feel of the Purple. You feel more “on-top-of” than “stuck-in” this mattress, which is great for combo sleepers who need mobility. This is a more uncommon feature for bed-in-a-box mattresses, so sleepers who don’t like sinkage should give the Purple a try.
  • The Purple mattress sleeps cool. This breathable mattress is a good choice for hot sleepers.

FAQ

Do I need to worry about off-gassing with the Lull mattress? What about with the Purple?

Both the Purple and the Lull mattress are shipped compressed in a box, so they may need to off-gas for a few hours after you unbox them. Almost all bed-in-a-box mattresses release gasses trapped in their boxes during manufacturing one they’re unwrapped, so this is nothing to be concerned about. Any odor should dissipate within a few hours.

Do I need a box spring with the Purple mattress? What about with the Lull?

No, you won’t need a box spring with either of these beds. Any hard flat surface will keep your mattress supported.

Can you flip the Lull mattress? What about the Purple mattress?

No, you can not flip the Purple or the Lull mattress. If you’re worried about wear, you can rotate your mattress 180 degrees every six months or so.
