Birch vs. Avocado: Firmness, Feel, and Construction

Firmness & Feel

We rate beds on a firmness scale of 1 to 10. 1 is the softest, plushest bed you can imagine, while 10 will be the firmest bed on the market. The Birch Natural has a medium-firm feel, while the Avocado Green has three firmness options that include Plush, Medium, and Firm (we tested the standard Firm model). The Avocado Green Plush has a box top whereas the Medium one has a pillow top, both of which add that extra softness.

Mattress Construction

The Birch Natural and Avocado Green are latex hybrid beds made with premium natural and organic materials, like latex, cotton, and wool. Both mattresses stand at a moderate 11 inches tall, making them suitable for most bed frames without adding too much height. They’re also both naturally hypoallergenic and cooling thanks to their breathable latex foam layers. One feature that makes the Avocado Green stand out is its zoned support, which has firmer and softer sections of the bed that help keep the spine in alignment with targeted pressure relief.

Birch vs. Avocado: Mattress Testing Performance

Pressure Relief

• Birch Natural Pressure Relief Score: 3/5

• Avocado Green Pressure Relief Score: 4/5

We use a pressure map to gauge pressure buildup.

I tested the Birch Natural and noticed almost no pressure laying on my back, but side sleeping generated red and yellow areas, indicating moderate to high pressure.

Our entire team found great pressure relief in the Avocado Green, with the exception of Loren, who had some pressure buildup along her shoulder while side sleeping on this bed.

Since the pressure wasn’t as significant on the Avocado Green, it wins in this category.

Support

• Birch Natural Support Score: 5/5

• Avocado Green Support Score: 5/5

My fellow testers and I lie on our sides, backs, and stomachs to determine how well a bed offers support for our spinal alignment.

We unanimously agreed that both the Avocado Green and Birch Natural offered excellent support with almost no sagging and great spinal alignment.

Keep in mind that pillow height can play a role in spinal alignment, but this is something you can easily swap out if your pillow loft is too low or too high.

Motion Isolation

• Birch Natural Motion Isolation Score: 3.5/5

• Avocado Green Motion Isolation Score: 2.5/5

We test motion isolation, or how well a mattress absorbs movement, by moving around on top of a bed and using a seismograph app to measure motion disturbances. Since latex and coils are springy materials, it’s no surprise that both the Birch Natural and Avocado Green scored lower in motion isolation. However, we felt motion isolation was slightly better on the Birch Natural and the movements shouldn’t cause too many issues for bed partners who aren’t super restless.

Temperature Regulation / Cooling

• Birch Natural Cooling Score: 4.5/5

• Avocado Green Cooling Score: 4/5

Neither the Birch Natural nor the Avocado Green were necessarily cool to the touch, but our thermal gun found that both beds did a solid job of regulating temperature thanks to their naturally cooling materials. The Birch Natural only went up 9 degrees while laying on it compared to 10 degrees on the Avocado Green, making it slightly better at cooling.

Bounce 

• Birch Natural Bounce Score: 5/5

• Avocado Green Bounce Score: 5/5

A bouncy mattress is important for active or combination sleepers as well as during sex since bounce helps prevent you from feeling “stuck” while laying on the bed. We test bounce by dropping a ball on the mattress and manually gauging how quickly the mattress returns to its original shape. Both the Birch Natural and Avocado Green had equally excellent bounce.

Edge Support

• Birch Natural Edge Support Score: 4/5

• Avocado Green Edge Support Score: 5/5

We sit and lie along the perimeter of each mattress for a minute to see how sturdy its edge support is. We found very little sink on the Avocado Green, but the Birch Natural was slightly squishier and sunk a bit more. Either bed should keep you secure while sleeping along the perimeter, but people with mobility issues who struggle to get in or out of bed might feel more comfortable on the Avocado Green.

Couples

• Birch Natural Couples Score: 4/5

• Avocado Green Couples Score: 4/5

We take several factors into consideration that can make the sleep experience more comfortable (and restful) for couples, like bounce, motion isolation, cooling, and edge support. The Birch Natural and Avocado Green were on par with one another for bounce and cooling, but the Avocado Green offered better edge support and the Birch Natural stronger motion control. Overall, we decided to rate both beds equally since each excelled in one area.

Accessibility 

• Birch Natural Accessibility Score: 5/5

• Avocado Green Accessibility Score: 5/5 

Accessibility is how well a mattress stands out against competitors. Each mattress offered great perks, which is why we ranked both 5 out of 5. Birch mattresses are committed to organic and natural materials, and the brand also offers discounts for military, students, teachers, and first responders. Avocado, meanwhile, offers a vegan-friendly version of the Avocado Green that’s wool-free.

Customer Service

• Birch Natural Customer Service Score: 4/5

• Avocado Green Customer Service Score: 4/5

We reach out to customer service ourselves to determine how helpful (and responsive) the options are. We had some technical issues with the chatbot on Avocado’s website, which is why we docked a point. We also found Birch’s customer service slightly lagging (and found ourselves bounced around a lot between a chat assistant and a live person), leading to a point removal there as well. However, the chat and phone representatives were friendly and helpful.
