Buying a mattress online can be overwhelming, especially when there are so many similar products available. How are you supposed to know which one is right for you?

Luckily, there are also mattresses out there that are distinctly different and offer unique pros and cons. That’s what we’ll be looking at today: three mattresses that offer unique benefits – one, all foam, another that’s an eco-friendly hybrid, and the third, made from an interesting GelFlex™ Grid. Depending on your preferences and needs, we’re sure one of these unique beds will work well for you.

Who I’d Recommend the Casper For

  • Sleepers who prefer traditional memory foam – Of the three mattresses here, Casper has the most traditional memory foam feel. You’ll sink into the top layer of memory foam for a gentle cradle.

  • Those who need lumbar support – The Casper mattress is zoned for support, which means it is more supportive beneath your hips and low back and softer beneath the shoulders. This design aims to keep your spine in a neutral alignment.

  • Light and average-weight sleepers – This mattress works best for light and average-weight sleepers. Heavyweight sleepers will need a more supportive bed.

Who I’d Recommend the Avocado For

  • Sleepers who prefer a hybrid bed – The Avocado Green mattress blends a traditional innerspring feel with the comfortable features of foam for a bed that is supportive, bouncy, and pressure relieving.

  • Eco-conscious shoppers – This is one of the most eco-friendly mattresses on the market, hands down. It uses materials like upcycled steel, sustainable natural latex, and organic cotton and wool.

  • Scent-sensitive sleepers – Scent-sensitive sleepers

Who I’d Recommend the Purple For

  • Sleepers who want a non-traditional feel – Purple is made from a unique Hyper-Elastic Polymer™ grid, which feels distinctly contouring and adaptive to your movements.

  • Hot sleepers – The unique waffle-like construction of this bed gives it over 1,400 air channels. This makes it breathable and cool to the touch; perfect for hot sleepers.

  • Sleepers with joint pain – Purple’s grid design will contour to the shape of your body in a way that the brand describes as “pressure-erasing.” It should help alleviate pain and pressure for those with joint issues.

Comparing Casper vs Avocado vs Purple: Top Similarities

  • Medium firm – All three of these mattresses have similar firmness levels (somewhere between a 6 and 6.5 out of 10.) This makes them great options for most sleepers.
  • Pressure relief – Each mattress has top layers that will feel pressure relieving and contour the body’s curves.
  • Price range – Each of these mattresses will cost somewhere between 1,200 and 2,000 dollars for a Queen.

Comparing Casper vs Avocado vs Purple: Key Differences

  • Eco-friendly vs. not – While the Avocado Green is one of the most eco-friendly, organic beds on the market, the Casper and Purple use entirely synthetic materials.
  • Their feel – These mattresses feel very different from one another. The Casper feels like a nice, gentle cradle; the Avocado feels more bouncy and supportive; and the Purple feels very adaptive to your movements.
  • Different for different body types – The Avocado is a good fit for average and heavyweight sleepers, whereas the Purple and Casper are better for light to average-weight sleepers.

Comparing Firmness, Support & Feel


We rate firmness on a scale from 1 to 10, with 1 feeling like a cloud and 10 feeling more like sleeping on your hardwood floor. With that in mind, these three mattresses all have similar firmness levels: The Casper is a 6, the Avocado a 6.5, and the Purple is also a 6.

This makes all three mattresses “medium-firm,” which means they are generally going to be the best fit for most body types and sleep positions.

firmness scale for 6 and 6.5


The Casper and the Avocado are both zoned for support – meaning, they are more supportive beneath the heavier area of your hips and low back. This makes either of these beds a good option for those who need more lumbar support. Additionally, the Avocado has coils, which can support more weight.

The Purple mattress offers support with its grid system, which should keep the spine neutrally aligned; however, it is not the best fit for heavyweight sleepers.


Perhaps the biggest difference between the three mattresses is how they feel. When you lie on the Casper, you’ll notice a ‘sinking’ feeling that’s typical of memory foam. It should feel dense and slow to respond.

The Avocado will feel a bit firmer and bouncy due to its latex and innerspring layers.

The Purple is made from a quick-response material, so it should mold to your body but quickly bounce back into its shape when you move.

Comparing Sinkage and Bounce

All-foam mattresses typically have more sinkage than bounce, and that is the case for the Casper and Purple mattresses. Of the two, Casper has more of that traditional, memory foam ‘sinking’ feeling, while the Purple still has a bit of bouncy because of how elastic the material feels.

The Avocado, on the other hand, is the bounciest of the three beds. This is because it has a layer of latex, a naturally bouncy material, as well as a layer of innerspring coils. This can be a plus for some sexually-active couples who want more bounce in their bed.

Comparing Motion Transfer

While bounce might be preferable for sexually-active couples, it doesn’t bode as well for those who are sensitive sleepers and share a bed. Mattresses with a lot of bounce (like the Avocado) tend to be worse at isolating motion, which means you’re more likely to feel it when someone moves on the other side of the bed.

Luckily, both the Casper and the Purple are great at isolating motion, with their all-foam constructions. If you’re a very sensitive sleeper and you’re worried about being woken up at night by your partner or perhaps furry friend, the Casper is probably the best out of the three.

Comparing Cooling

All three of these mattresses incorporate cooling into their design. The Casper uses a top layer of perforated foam, so air can move quickly through it. The Avocado has a layer of coils, which make the bed breathable, as well as natural latex and organic wool, which are temperature-regulating materials. Finally, Purple’s unique Hyper-Elastic Polymer™ material is temperature neutral, so heat shouldn’t build up around your body while you’re sleeping.

All that said, the coolest of the three mattresses is going to be the Avocado, since it is the only mattress with coils for that extra breathability.

Comparing Construction (Materials & Quality)

Casper Construction

This bed-in-a-box will arrive at your door, compressed in a box. Once the Casper decompresses it will measure 11 inches tall. All wrapped up in a polyester cover are three layers of foam.

original Casper bed layers image graphics
  • The first foam layer in the Casper is made from AirScape™ foam, which is perforated for coolness and has a bit of bounce.
  • The middle foam layer is made up of 2 inches of Zoned Support™ foam. This memory foam is zoned to be firmer beneath the hips, where most people carry more weight, and softer beneath the shoulders and knees. This will create pressure relief and help to keep the spine in proper, neutral alignment while you’re sleeping.
  • The base layer is made up of a dense and durable foam. This layer provides the overall foundation for the bed along with delivering support for the sleeper.

Avocado Construction

The Avocado is also a bed-in-a-box, and once it decompresses, will also measure 11 inches tall. The first thing you’ll notice is the cover: a soft, organic cotton material with tufting and wool yarn rosettes. This tufting should make the cover more durable over time.

Avocado Green layers of the mattress new design
  • Beneath the cover, is the top comfort layer. It is made from GOLS-certified natural Dunlop latex, a heat-resistant and breathable material.
  • The second layer is made from individually-wrapped, upcycled steel coils. These coils are zoned to support the lumbar area and keep the spine neutrally aligned through the night. They’ll also give the bed even more breathability and bounce.
  • The base layer is made of a firmer Dunlop latex than the top layer for additional body support.
    The perimeter is reinforced with stronger coils so the edges of the bed won’t sag over time.

Purple Construction

Like the other mattresses, the Purple will be delivered compressed in a box. Once it decompresses, it will measure just 9.5 inches tall. The cover is made of a SoftFlex material; a blend of polyester, viscose, and lycra that is adaptive and will move with the unique grid material of the mattress.

Purple Construction Layers
  • Below the cover is Purple’s unique pressure-relieving grid. It is made of 2 inches of Hyper-Elastic Polymer™. This highly durable and flexible material should evenly distribute your weight, which is why it is described as “pressure-erasing.”
  • The middle layer is made up of 3.5 inches of medium-soft polyurethane foam. This layer acts as a transition layer between the top and base of the bed, and it also provides some extra pressure relief.
  • The base layer is made up of 4 inches of firmer polyurethane foam. This layer gives the entire bed its shape, foundation, and durability.

Comparing Company Policies & Price

  • Warranty – Both the Casper and Purple mattresses come with a 10-year limited warranty, and the Avocado Green comes with a 25-year warranty.
  • Shipping – Casper ships for free throughout the contiguous USA and Canada. Avocado ships for free throughout the USA, including Alaska and Hawaii. Purple ships for free throughout the contiguous USA and Canada, with a small fee to ship to Alaska or Hawaii. In-home delivery is available for all three for an additional fee.
  • Trial Period – Casper and Purple both come with a 100-night risk-free trial period, and Avocado comes with a 365-night risk-free trial period.

(Avocado asks that you donate your bed and will coordinate that with you.) With Purple, you’ll need to try it out for 21 days before you can initiate a return, and unlike Casper and Avocado, you’ll need to pay for shipping if you return your mattress.
  • Price – All three mattresses are somewhere in the 1,200 to 2,000-dollar range for a Queen.

Final Thoughts

After reading this review, you can see how the Casper, Avocado, and Purple are three unique mattresses, each with their own benefits that are better suited for different people.

If you love the feel of memory foam and want a medium-firm bed-in-a-box, the Casper is your best bet. If you’re more interested in an organic mattress with some bounce and more support, you can’t go wrong with the Avocado. Meanwhile, the Purple is an excellent choice for those who want a technologically advanced grid system that adapts to the shape of the body for maximum pressure relief.
