Helix Midnight Review Highlights
- Breathability: The Midnight earned top marks for breathability, thanks to the breathable mattress cover and airflow through the coil layer. Your body heat is able to travel out of the mattress, so it doesn’t stick around causing you to sweat and kick off the covers.
- Edge Support: The Helix Midnight is an all-around supportive mattress, and that support is felt from edge to edge. The coil system features reinforced edge support, so you can sit or lie down near the edge of the bed without sliding off.
- Motion Transfer: The Helix Midnight earned a remarkably high score for motion transfer. Our testers were impressed with the Midnight’s ability to isolate motion, especially with a partner in the bed.
- Fan Favorite: The Helix Midnight is the most popular Helix mattress, thanks to its medium firmness. Back sleepers and stomach sleepers are well supported, while side sleepers get an adequate cushion for sensitive pressure points.
Purple Review Highlights
- Spinal Alignment: The Purple Original mattress earned close to a perfect score for spinal alignment. It keeps your back in a neutral position while you sleep, which translates into less back pain and stiffness when you wake.
- Pressure Relief: The Purple Grid that makes up the comfort layer of all Purple mattresses is designed to relieve pressure on your shoulders and hips. It scored well in this category, with very little stress on our testers’ pressure points.
- Cooling: The Purple mattress features a hyper-elastic polymer grid that has similar cooling properties to gel. It’s also designed with a waffle-like shape that creates thousands of channels for airflow.
- Durability: Beneath the Purple Grid, two layers of high-density foam improve the lifespan of the mattress.
Compare Mattress Structure
The Helix Midnight and Purple Original are both technically hybrid mattresses, but they have very different constructions. The Midnight is a blend of memory foam and pocket coils, while the Purple pairs their proprietary hyper-elastic polymer GelFlex™ Grid with high-density foams. The Purple has a firmer feel than the Midnight, although both range in the medium to medium-firm category.
The top layer in the Helix Midnight has a medium firmness that cushions pressure points. The transition layer is also relatively soft while preventing you from feeling the hundreds of pocket coils at the mattress base. The entire bed rests on a layer of durable support foam and is covered with soft, breathable fabric.
The Purple Original mattress is topped with the GelFlex™ Grid, which is shaped like a waffle and has the soft, cooling feel of gel. It’s designed to evenly distribute your body weight and provide superior pressure relief. Beneath the GelFlex™ Grid, a layer of soft comfort foam is both responsive and cushioning. A final layer of high-density polyfoam keeps the mattress durable and stable for years, and an extra stretchy mattress cover allows you to sink into the mattress surface.
The Helix Midnight and Purple Original mattress have similar price points, and the Purple is never more than $250 more than the Midnight. Additionally, Purple offers financing through Affirm and SplitIt, and Helix offers financing through Klarna and Katapult for orders costing $499-$2,400.
Birch Natural Mattress Review Highlights
- All-Natural: Birch is an all-natural bedding brand by Helix. The mattress is made with natural materials, such as GREENGUARD Gold certified foam, New Zealand organic wool. We even voted the Birch one of the Best Natural Organic Mattresses.
- Motion Isolation: If you sleep with anyone else, you may be sensitive to their movements across the mattress surface. The Birch mattress does a great job of isolating motion at its source, so you are disrupted if sleeping partners get up or move around.
- Durable: All Birch mattresses are handcrafted with high-quality materials. They are built to last, which is why they are also protected against defects by a 25-year warranty.
- Spinal Alignment: Good posture has an impact on health across your whole body, including your nervous system, digestion, and energy levels. The Birch mattress keeps your spine in a healthy neutral position all night long by evenly distributing your weight.
Purple Hybrid Mattress Review Highlights
- Cooling: The Purple Hybrid mattress pairs the hyper-elastic polymer GelFlex™ Grid with a coil layer. The result is an overall cool, breathable mattress and a more comfortable night’s sleep.
- Durability: Hyper elastic polymer is one of the most durable mattress materials around, and it is paired with sturdy coils in the Purple Hybrid. This mattress supports even plus-sized sleepers for years and years.
- Pressure Relief: The Purple GelFlex™ Grid lifts pressure off of your shoulders and hips without the sinking feeling of traditional memory foam.
- Responsiveness: A layer of bouncy coils sits at the base of the Purple Hybrid. These coils enable the mattress to keep up with your changes in position.
Compare Mattress Structure
The Birch Natural and Purple Hybrid mattresses are quite different, despite both being medium-firm mattresses (7/10 on the firmness scale). For starters, the Birch is constructed with all-natural materials, such as wool, latex, and organic cotton, while the Purple Hybrid is made with the hyper-elastic polymer GelFlex™ Grid and polyfoam. The Purple sleeps decidedly cooler than the Birch, but the Birch provides slightly better motion isolation.
The Birch mattress has a certified organic cotton cover and wool-rayon fire retardant layer. Beneath the cover, a layer of soft Birch wool provides cushion to pressure points and resists body impressions. The transitional Talalay latex layer is cooling and responsive, and the steel coil support layer helps to isolate motion. An extra layer of wool batting forms a durable base layer.
The Purple Hybrid is covered with an extra-stretchy viscose-polyester-lycra fabric blend. The hyper-elastic polymer GelFlex™ Grid is breathable, durable, and pressure relieving. A thin layer of transitional polyfoam sits between the Grid and the bouncy pocket coils. A final layer of high-density foam sits at the mattress base.
Both of these mattresses are durable investments that cost close to $2,000. The Purple Hybrid runs $200-$300 more than the Birch, but financing is offered by both companies. Also, note that the Purple Hybrid is offered in every size except Twin, while the Birch doesn’t offer a Split King option.
Helix Midnight Luxe Review Highlights
- Pressure Relief: The Helix Midnight Luxe performs especially well in the area of pressure relief, which is vital for side sleepers and enhances comfort for every sleeper.
- Responsiveness: We gave the Midnight Luxe a high score for responsiveness because our testers had such an easy time getting comfortable when changing their sleeping position. This is an especially important feature for combination sleepers.
- Spinal Alignment: A properly aligned spine and good posture help keep you free of back pain, so it is good news that the Luxe does a great job of maintaining healthy spinal alignment.
- Cooling: The Midnight Luxe is an extra cool mattress, designed with hot sleepers in mind. The mattress cover is made with phase change material that keeps the mattress surface at a neutral temperature. Plus, the coil system improves airflow.
Purple Hybrid Premier Mattress Review Highlights
- Firmness Options: The Purple Hybrid Premier has the same construction as the Purple Hybrid, but it’s offered with a 3” or 4” Purple Grid layer. It has a much softer feel than both the Purple Original and Purple Hybrid.
- Spinal Alignment: The Hybrid Premier earned a 9.5/10 for spine alignment. You can count on minimal stiffness and no back pain after a good night’s sleep.
- Cooling: The Hybrid Premier is made with very little foam, so there isn’t much to absorb body heat. Additionally, the coil layer creates lots of space for airflow, so it keeps you cool while you sleep.
- White-Glove Delivery: Purple offers free white glove delivery with all Hybrid Premier purchases, so you don’t have to worry about moving the mattress into your home or setting it up on your bed frame.
Compare Mattress Build
The Helix Midnight Luxe and Purple Hybrid Premier are both luxury mattresses with hybrid constructions. The key difference is firmness level – the Midnight Luxe has a medium feel, and the Hybrid Premier is far plusher. Additionally, you can choose between a 3” and 4” comfort layer for the Hybrid Premier, depending on your preference and body type.
The Helix Midnight Luxe is wrapped in a temperature regulating fabric that is infused with phase change material. The material absorbs or releases heat, depending on what is needed to maintain a neutral temperature. The mattress is topped with a quilted pillow top and two pressure-relieving memory foam layers. It’s supported by over 1,000 pocket coils and durable base foam.
The Purple Hybrid Premier is covered with Premium StretchMax fabric that enables you to experience the full pressure-relieving properties of the GelFlex™ Grid. In other words, you won’t feel suspended in the fabric above the 3” or 4” GelFlex™ Grid comfort layer. Next, a layer of memory foam absorbs motion and transitions your body into the pocket coil layer, which is designed to add responsiveness and stability to the mattress.
Both of these luxury mattresses have higher price points, but keep in mind that you can finance either. The Purple Hybrid Premier is on average, $1,000 more than the Midnight Luxe. It’s also not available in Twin size, so you’ll get extra length on the Twin XL. You can opt for a 3″ or 4″ Purple Hybrid Premier model depending on your preference.

- Washable Cover: The mattress cover is removable and machine washable so you don’t have to worry about cleaning up accidents.
- Affordable Price: For a luxury children’s mattress, the Kid’s Purple bed is reasonably priced.
Compare Mattress Build
The Helix Kids and Kid’s Purple mattresses are both hybrid models that use a combination of foam and innerspring. The major difference between the two is that the Helix Kids is double-sided, with a firm and soft side, while the Kid’s Purple is a one-side mattress with a medium-firm firmness level.
The Helix Kids uses an antimicrobial, water-repellent cover to protect the mattress from accidents. Beneath the cover is a fire retardant layer. A firm foam layer and soft foam layer sandwich the innerspring to provide excellent cushioning. The mattress then concludes with another fire retardant layer.
The Kid’s Purple mattress starts with a removable cover made out of polyester, spandex and cooling PE. The bed then consists of Purple’s famous polymer grid, which evenly distributes weight and causes a floating feeling. Beneath the grid layer is a transitional foam that provides excellent pressure relief. The Kid’s Purple mattress also has a high-density support layer that offers stability and durability for years to come.
Both of these luxury children’s mattresses have higher price points, but keep in mind that both companies run regular sales and discounts. The Kid’s Purple is a little more than the Helix Kids. It’s also only available in the Twin size, whereas Helix also offers a Full-size option.
|Helix Kids||Kid’s Purple|
The Helix and Purple mattresses have the same dimensions, except the Birch mattress Twin and Twin XL sizes are 1” wider than the Purple, and the Purple Full size is 1” longer than the Helix. Additionally, Purple mattresses have a lower profile than Helix mattresses. The Original Purple mattress is only 9.25” thick.
|Thickness||11” – 14”||9.25” – 13”|
|Twin||38”-39” x 75”||38” x 75”|

Trial Periods Explained
Both Helix and Purple customers get 100 nights to trial their new mattresses, plus free shipping and returns. Helix customers need to sleep on their mattress for at least 30 days before requesting a return, and Purple customers need to keep their new bed for at least 21 days. This is called the mattress break-in period, and it allows your body to fully adjust to the new sleeping surface before you make a final decision.
Additionally, Helix will ship you a free mattress topper during the sleep trial if you want to adjust the firmness of your bed. And don’t forget that Purple provides free white glove delivery for their Hybrid Premier mattresses.
Purple mattresses are protected against defects like sagging for a period of 10 years. Helix mattresses are covered for 10-25 years (Helix Midnight – 10 years, Midnight Luxe and Plus – 15 years, Birch – 25 years).
You’re going to get excellent pressure relief on all of these beds, but Helix beds provide better motion isolation and responsiveness. Purple mattresses are more consistently cooling and are also a bit more expensive, but you can try them before you buy at retail partners across the country.
