After comparing specs, materials, and owner feedback, the Purple Restore Hybrid is our overall winner for its pressure relief and cooling. The Lull Original Memory Foam is the better pick if you want a simpler all-foam feel at a lower entry point with steady contouring.
Lull and Purple are two of the most searched bed-in-a-box brands, and shoppers often pit them head to head because they take very different approaches to comfort. Lull leans into traditional memory foam with a gel-infused top layer, while Purple builds its lineup around its hyper-elastic polymer grid that flexes under pressure points. We compared both lineups based on published specs, material certifications, trial terms, and recurring themes in verified owner reviews rather than physical testing.
Below we rank seven mattresses across both brands so you can match firmness, sleeping position, and cooling needs to the right bed. We note who each model suits, what owners consistently praise, and where the trade-offs show up. Whether you sleep hot, share a bed, or need extra support for your hips and shoulders, there is a clear fit here.
Purple Restore Hybrid
The Purple Restore Hybrid pairs the brand's GelFlex Grid with responsive coils for a balance of contouring and support. Owners describe a unique buoyant feel that adapts to movement without the sinking sensation of dense foam. The grid's open channels promote airflow, which helps the bed sleep cooler than many all-foam rivals.

The picks, compared
Purple Restore Hybrid
Most sleepers wanting pressure relief plus airflow · Type: Hybrid (grid over coils) | Firmness: Medium | Trial: 100 nights
The Purple Restore Hybrid pairs the brand's GelFlex Grid with responsive coils for a balance of contouring and support. Owners describe a unique buoyant feel that adapts to movement without the sinking sensation of dense foam. The grid's open channels promote airflow, which helps the bed sleep cooler than many all-foam rivals.
What owners report: Owners frequently report relief at the hips and shoulders along with strong edge support from the coil base. A smaller group notes the surface feel takes a few weeks to get used to compared with standard foam.
- GelFlex Grid relieves pressure points well
- Coil base adds support and bounce
- Sleeps cooler than typical memory foam
- Heavier and harder to move alone
- Distinct grid feel is not for everyone
Lull Original Memory Foam
Shoppers wanting classic foam contouring at a friendly entry point · Type: All-foam | Firmness: Medium-firm | Trial: 100 nights
The Lull Original is a three-layer memory foam bed with a gel-infused top layer designed to draw heat away from the body. It delivers the slow, cradling contour many memory foam fans look for, with a medium-firm feel that suits a range of sleepers. As an all-foam build it ships compressed and sets up quickly.
What owners report: Owners praise the value and the body-conforming comfort, especially for back and side sleeping. Some mention the bed runs warmer than expected during summer months despite the gel layer.
- Strong contouring for the price
- Medium-firm feel suits many sleepers
- Quick, low-fuss setup
- Can trap more heat than hybrid options
- Less edge support than coil beds
Purple Hybrid Premier 4
Hot sleepers who want maximum airflow and pressure relief · Type: Hybrid (4-inch grid over coils) | Firmness: Medium-soft | Trial: 100 nights
The Hybrid Premier 4 uses a thicker layer of Purple's GelFlex Grid over responsive support coils for deeper pressure relief. The open-grid design and breathable cover make it one of the most airflow-friendly beds in either lineup. It is built for sleepers who run hot and want a plush yet supportive surface.
What owners report: Owners consistently call out how cool the bed sleeps and how well it cushions pressure points. The main drawback noted is the premium positioning and the considerable weight of the mattress.
- Excellent airflow and temperature neutrality
- Deep pressure relief from thick grid
- Responsive coils keep you on top of the bed
- Very heavy to maneuver
- Sits at the top of the price range
Lull Luxe Hybrid
Couples wanting foam comfort with coil support and edge stability · Type: Hybrid (foam over coils) | Firmness: Medium-firm | Trial: 100 nights
The Lull Luxe Hybrid combines comfort foam layers with individually wrapped coils for added support and reduced motion transfer. It gives the contouring feel Lull is known for while adding bounce and stronger edges than the all-foam Original. The coil core also improves airflow compared with the brand's full-foam model.
What owners report: Owners report good motion isolation and sturdier edges, which couples appreciate when sharing the bed. A few note it feels firmer than they anticipated during the break-in period.
- Coils add support and edge stability
- Better motion isolation for couples
- More airflow than all-foam Lull
- Firmer than expected at first
- Heavier than the all-foam Original
Purple Plus
Side sleepers wanting extra grid cushioning for shoulders and hips · Type: Foam plus grid | Firmness: Medium | Trial: 100 nights
The Purple Plus adds an extra comfort foam layer beneath the GelFlex Grid for a softer, more cushioned feel. That added give helps side sleepers offload pressure at the shoulders and hips while the grid keeps the spine supported. It bridges the gap between the entry grid model and the pricier hybrids.
What owners report: Side sleepers report meaningful pressure relief and a softer surface than the base grid model. Some heavier sleepers note they prefer the coil hybrids for more underlying support.
- Softer feel suits side sleepers
- Grid still relieves pressure points
- Good airflow for an all-foam-style build
- May lack support for heavier sleepers
- Less edge support than the hybrids
Purple Mattress
Shoppers wanting the signature grid feel at the lowest Purple entry · Type: Grid over foam | Firmness: Medium-firm | Trial: 100 nights
The original Purple Mattress places the GelFlex Grid over a foam base, offering the brand's distinctive responsive feel without the hybrid coil system. It sleeps cooler than most foam beds thanks to the open grid and suits back and stomach sleepers who want firm support. As the entry model it is the most accessible way into the Purple lineup.
What owners report: Owners like the cooling and the unique no-sink surface that makes moving around easy. The most common complaint is that the all-foam base offers less support and bounce than the hybrids.
- Signature grid feel at the lowest entry
- Sleeps cool with strong airflow
- Easy to move on the surface
- Foam base lacks coil support
- Edge support is modest
Lull Memory Foam Mattress King
Back and stomach sleepers wanting firmer all-foam support · Type: All-foam | Firmness: Firm | Trial: 100 nights
The Lull Memory Foam in its larger king configuration delivers the same three-layer build with a supportive, medium-firm surface that leans firm for many sleepers. It suits back and stomach sleepers who want their hips kept in line rather than a plush cradle. The gel-infused comfort layer aims to keep the surface from overheating.
What owners report: Owners who prefer firmer beds say it keeps their spine aligned and reduces lower-back aches. Side sleepers occasionally find it too firm for shoulder pressure relief.
- Firmer support suits back and stomach sleepers
- Helps keep the spine aligned
- Gel layer aims to limit heat buildup
- Too firm for some side sleepers
- All-foam edges compress when sitting
Frequently asked questions
Is Lull or Purple better for hot sleepers?
Based on specs and owner feedback, Purple generally sleeps cooler because its GelFlex Grid has open channels that promote airflow. Lull uses gel-infused foam to manage heat, but all-foam beds tend to retain more warmth than a grid-and-coil design. Hot sleepers usually lean toward the Purple Restore Hybrid or Hybrid Premier 4.
What is the main difference between Lull and Purple?
Lull builds traditional memory foam mattresses with a slow, contouring feel, while Purple is known for its hyper-elastic polymer grid that flexes only where you apply pressure. The grid gives a more responsive, buoyant surface, whereas Lull offers a familiar cradling sensation. Your preference between contouring and responsiveness will usually decide the winner.
Which is better for side sleepers?
Side sleepers often do well on the Purple Plus, which adds a softer comfort layer to cushion the shoulders and hips while the grid keeps the spine supported. The Lull Original also contours nicely for side sleeping at a lower entry point. Heavier side sleepers may prefer the coil support of a Purple hybrid.
Do both brands offer a sleep trial?
Yes, both Lull and Purple typically offer a 100-night trial so you can test the bed at home before committing. Owners report that the break-in period matters, since both memory foam and the Purple grid can feel different in the first few weeks. Check the current terms on each brand's site before ordering.
Are Lull and Purple mattresses good for couples?
Both can work for couples, but the choice depends on motion isolation and edge support. The Lull Luxe Hybrid and Purple Restore Hybrid both add coils that improve edge stability and reduce motion transfer compared with all-foam models. Couples who share a smaller bed often appreciate the coil-based options.
The verdict
For most sleepers, the Purple Restore Hybrid is our overall winner thanks to its grid-plus-coil pressure relief, cooling, and edge support. Hot sleepers who want maximum airflow should look at the Purple Hybrid Premier 4, while shoppers who prefer classic memory foam contouring at a lower entry point will be well served by the Lull Original Memory Foam. Match the firmness and feel to your sleeping position and you will find a strong fit in either lineup.
