Lull Vs Purple

If you’re looking at mattresses, you might be comparing the popular Lull vs Purple brands. Both offer unique approaches to sleep, but they feel and perform quite differently. This guide will help you understand their core technologies, who they’re best for, and how to decide between them. We’ll break down everything from materials to firmness and price.

Your choice will depend heavily on your sleep style and what you find comfortable. One uses memory foam, while the other relies on a hyper-elastic polymer grid. Let’s get into the details so you can make a clear choice.

This head-to-head comparison looks at the flagship models from each company. We’ll examine their construction, feel, and performance in key areas. Remember, “Lull” refers to its specific foam layers, and “Purple” is defined by its distinctive Purple Grid. They are fundamentally different products.

Core Technology and Construction

The biggest difference lies in what these mattresses are made of. This is the heart of the Lull vs Purple debate.

What is a Lull Mattress Made Of?

The original Lull mattress is an all-foam, three-layer design. It’s built for balanced comfort and support.

Top Layer: A gel-infused memory foam. This layer aims to cushion your body and help with temperature regulation by dissipating heat.
Middle Layer: A transition foam. This prevents you from sinking too deeply into the firmer base below, providing a bit of bounce.
Base Layer: A high-density support foam. This foundational layer gives the mattress its shape and long-term durability.

It’s a straightforward, proven foam design focused on contouring and pressure relief.

What is a Purple Mattress Made Of?

The original Purple mattress (now often called the Purple Grid) uses a unique material. Its construction is more complex.

Top Layer: The Purple Grid. This is a hyper-elastic polymer material arranged in a grid pattern. It’s soft where you need it (like under shoulders and hips) and firm where you don’t. It’s highly responsive and breathable.
Comfort Layer: A polyurethane foam. This sits beneath the grid to add additional cushioning.
Base Layer: A dense polyurethane foam. This provides the core support for the entire mattress.

The Purple Grid is designed to flex under pressure, promoting airflow and a “floating” feel rather than a sinking sensation.

Feel and Firmness Comparison

How a mattress feels is subjective, but we can describe the general experience.

The Lull mattress is generally rated around a medium-firm (6-6.5 out of 10). When you lie down, you’ll experience a slow sink-in feeling typical of memory foam. It contours to your body’s curves, which can be great for side sleepers needing hip and shoulder relief. There’s minimal bounce, which some couples prefer for motion isolation.

The original Purple mattress is firmer, often rated a 6.5-7 out of 10. The initial feel is very different. Instead of sinking, you feel the grid collapsing under your heavier body parts while supporting the lighter ones. This creates a cradling effect without deep contouring. The material is much more responsive and bouncy than memory foam.

Performance Breakdown

Let’s see how they handle specific sleep needs.

Motion Isolation

If you share a bed, you’ll want a mattress that absorbs movement.

Lull: Excellent. Its all-foam construction, especially the memory foam top, does a superb job of absorbing motion. Your partner is unlikely to feel you getting in and out of bed.
Purple: Good, but not perfect. The Purple Grid is responsive, so some motion transfer can occur. However, it’s still better than a traditional innerspring mattress. The foam layers underneath help dampen movement.

Temperature Regulation

Do you sleep hot? This is a critical factor.

Lull: The gel infusion in the top foam is meant to help, but it’s still a memory foam mattress. Foam tends to trap body heat. It sleeps temperature-neutral for many, but strict hot sleepers might find it gets warm.
Purple: Often wins here. The Purple Grid has open channels that allow air to circulate freely. This promotes heat dissipation, making the mattress sleep noticeably cooler than most foam beds.

Edge Support

Good edge support means you can use the full surface of the bed.

Lull: Fair. Like most all-foam beds, the edges will compress when you sit on them. You might feel some roll-off when sleeping near the side.
Purple: Slightly better. The grid material is more supportive at the perimeter, and the firm base foam helps. It’s not as strong as a hybrid, but it’s generally adequate for most sleepers.

Which Sleep Position is it Best For?

Your preferred sleep style is the best guide.

Side Sleepers

Side sleepers need pressure relief on hips and shoulders.

Lull: A very good choice. Its contouring memory foam cradles these pressure points nicely, promoting spinal alignment for average-weight side sleepers.
Purple: Can work, especially for those who prefer a firmer feel. The Grid adapts to provide pressure relief, but some find it too firm for side sleeping, particularly lighter individuals.

Back and Stomach Sleepers

These positions require firmer support to keep the spine neutral.

Lull: Suitable for back sleepers who like a medium-firm feel. It might be too soft for some stomach sleepers, who could experience hip sagging.
Purple: Often recommended. The firmer, supportive feel of the Purple Grid helps maintain a flat spinal alignment for both back and stomach sleepers.

Combination Sleepers

If you move around a lot, ease of movement matters.

Lull: The memory foam can create a slight “stuck” feeling, making it harder to change positions quickly.
Purple: The responsive grid makes it very easy to move and switch positions throughout the night, which is a significant advantage for combination sleepers.

Pricing and Value

Price is always a consideration. Both companies offer regular discounts, but here’s a general comparison for a Queen size:

Lull: Typically positioned as a more budget-friendly option. It’s often priced lower than the original Purple mattress, offering solid value for a simple, effective foam bed.
Purple: Commands a higher price due to its proprietary material and technology. You’re paying for the unique cooling and feel of the Grid.

Both come with standard sleep trials (usually 100 nights) and warranties (10 years). Always check their websites for the latest promotions.

The Decision Guide: Choosing Between Them

Still unsure? Ask yourself these questions.

Choose Lull if:

You prefer the classic, contouring hug of memory foam.
You are a dedicated side sleeper or need deep pressure relief.
Motion isolation is your top priority (you have a restless partner).
You want a straightforward, high-quality foam mattress at a competitive price.
You don’t typically overheat at night.

Choose Purple if:

You sleep hot and need a cooler sleeping surface.
You dislike the sinking feeling of memory foam and want a more responsive, bouncy bed.
You are a back or stomach sleeper, or a combination sleeper who changes positions often.
You’re intrigued by the unique feel of the Grid technology and are willing to pay a premium for it.
You want better edge support than a typical all-foam bed.

Beyond the Original: Other Models

Both companies have expanded their lines. Here’s a quick look.

Lull Luxe

This is an upgraded version of the original Lull. It adds a plush, breathable cover and an extra layer of cooling gel foam. It’s designed to be softer and sleep cooler than the original, offering a more premium feel for those who want it.

Purple’s Lineup (Purple, Purple Plus, Purple Hybrid, Purple Hybrid Premier)

Purple now offers a range. The “Plus” adds more foam for a softer feel. The “Hybrid” models replace the foam base with pocketed coils, enhancing support, bounce, and cooling further. The “Premier” models have thicker Grid layers (3″ or 4″) for a plusher, more pressure-relieving experience. If you love the Grid concept but need something softer or more supportive, explore these options.

Setting Up and Caring for Your Mattress

Both mattresses come compressed in a box.

Unbox Carefully: Move the box to your room before opening. Use scissors carefully to avoid damaging the mattress.
Unroll and Position: Place the rolled mattress on your bed frame or foundation. Carefully cut the plastic wrap and watch it expand.
Give it Time: It may take 24-72 hours to fully expand and for any slight odor (common with new foam) to dissipate. Open a window to help.
Use a Protector: To maintain your warranty and keep it clean, use a waterproof mattress protector from day one.
Rotate Regularly: Rotate the mattress head-to-foot every 3-6 months to ensure even wear. They are not designed to be flipped.

Frequently Asked Questions (FAQ)

Which mattress is softer, Lull or Purple?

The original Lull mattress is generally softer and has more contouring than the original Purple. The Purple feels firmer and more supportive with a responsive lift. However, Purple’s newer “Plus” and “Premier” models are made to be much softer.

Does the Purple mattress smell when new?

There might be a slight odor from off-gassing when you first open it, which is normal for most bed-in-a-box mattresses. It’s non-toxic and usually dissapates within a few days in a well-ventilated room.

Can I use these mattresses on an adjustable base?

Yes, both the Lull and Purple mattresses are compatible with adjustable bed frames. Their flexible materials bend without damage, making them a good choice for adjustable bases.

Which bed is better for back pain?

It depends on the cause of your back pain. Purple’s firmer, supportive grid is often recommended for back and stomach sleepers with alignment issues. Lull’s pressure-relieving contour can benefit side sleepers. If you have chronic pain, consulting a doctor is always best before making a purchase.

How long do Lull and Purple mattresses typically last?

Both are expected to last 7-10 years with proper care. Their 10-year warranties reflect this expectation. Using a supportive foundation and rotating them regularly will help maximize there lifespan.

Final Thoughts

Choosing between Lull and Purple comes down to personal preference for feel and sleep needs. Lull offers a comfortable, affordable memory foam experience with great motion isolation. Purple provides a unique, cooler, and more responsive sleep surface with its innovative Grid.

The best way to decide is to take advantage of their generous home trial periods. Your body will tell you which one is the right fit for a better night’s rest. Remember to consider your primary sleep position, temperature needs, and whether you prefer to sink in or feel cradled on top.
