Birch Plush Organic Mattress Topper review: natural, responsive support for all sleep positions

Launched back in 2019, Birch is a sub-brand of the luxury mattress company Helix. The Helix team, responsible for some of this year's best mattresses on the market, created Birch to build natural and sustainable sleep products, that use organic materials. The all-natural brand's signature bed topper, the Birch Plush Organic Mattress Topper, has been on my radar since I joined the review team back in 2023, and I recently got the chance to test it out.

This year's best mattress toppers guide is full of memory foam options, so I was eager to see if Birch's bed topper would be the first latex topper to make the cut. To find out, I put a full-sized Birch Plush Organic Mattress Topper on a memory foam mattress and slept on it for two weeks. Here's my experience.

Birch Plush Organic Mattress Topper: Review in brief

The Birch Plush Organic Mattress Topper is made from a 2" thick layer of natural latex and an organic cotton cover. According to the brand, the Plush Organic Topper is "crafted from breathable, natural and organic materials".

So, who is this mattress topper for? Well, let's get the obvious out of the way: eco-conscious (and health-conscious) shoppers who want a sustainable sleep product made from clean, non-toxic materials.

But what's it like to sleep on? Well, as a side and back sleeper, I need something soft enough to soothe my shoulders when side sleeping but firm enough to support my lumbar region when sleeping on my back. Thanks to the spongy-yet-firm latex, I slept comfortable in both sleep positions.

However, don't expect the mattress topper to live up to its "Plush" title. I must admit, I was not surprised to find it was not as soft as the name suggested, as latex is known to be on the firmer side. That isn't to say it's uncomfortable, though.

In fact, it made my quicksand-y memory foam bed more responsive and less stifling, so it's a perfect choice for restless sleepers who need ease of movement when switching sleep positions. The latex topper is also a good choice for anyone who feels trapped by the sink-in softness of their memory foam bed.

The 2" height is thick enough to transform any bed, but thin enough not to add too much height to any mattresses over 14".

That said, the design does have a few shortcomings. Firstly, there are no anchor straps to keep the Plush Organic Mattress Topper in place on your bed. Secondly, the soft-touch organic cotton cover is non-removable and spot clean only.

While the bed topper would have benefitted from these features, it kept clean and never shifted the whole time I was testing it thanks to a fitted mattress protector and sheet.

As for price and deals, a queen-size Plush Organic Mattress Topper is $532 at MSRP, but it's usually $399 thanks to a regular 25% discount. Yes, it's a premium price, but it's made from premium materials and comes with two pretty generous benefits: a 100-night sleep trial and 10-year warranty.

Birch Plush Organic Mattress Topper: Price & deals

• A premium bed topper, a queen is often $399 with a 25% discount
• Available to buy at both Helix Sleep and Birch
• Includes a generous 100-night trial and 10-year warranty

The Birch Plush Organic Matress Topper uses premium organic materials, so it's only natural (no pun intended) that it would have a luxury price tag. However, if you consider that the average queen latex bed topper is $575, a queen Birch's usual $399 price (thanks to a regular mattress sale) is relatively affordable. You can also find a 20-25% discount on the topper in the Helix mattress sale.

Here are both the MSRPs and sale prices for the The Birch Plush Organic Mattress Topper in all available sizes:

• Twin MSRP: $372 (usually $279)
• Twin XL MSRP: $385.33 (usually $289)
• Full MSRP: $498.57 (usually $374.01)
• Queen MSRP: $532 (usually $399)
• King MSRP: $652 (usually $489)
• California King MSRP: $652 (usually $489)

Plus, it's a cost-effective alternative to the best organic mattresses (which typically has an average price of $1,665 for a queen) or Naturepedic's latex topper (whose $749 queen price was listed as a drawback in the Naturepedic Adagio Organic Latex Mattress Topper review.)

Despite the cheaper price, the Birch matches Naturepedic's benefits: free shipping, a 10-year warranty, and 100-night sleep trial. Considering that the average topper trial is 30 nights and the average warranty is around three to five years, the Birch Plush Organic Mattress Topper boasts the generous extras you would typically find for full-fledged mattresses.

The Birch Plush Organic Mattress Topper is available in six sizes at both Birch and Helix: twin, twin XL, full, queen, king, and Cal king. Both Helix and Birch shoppers can regularly enjoy a 20% or 25% discount, which reduces a queen to $399, plus free shipping, a 100-night sleep trial, and a 10-year warranty.

Birch Plush Organic Mattress Topper: Design & Materials

• Features 2" of (presumably Dunlop) latex with organic cotton cover
• Non-removable, spot-clean only cover without corner straps
• Uses natural, sustainable, and certified-organic materials

A major draw of the Birch Plush Organic Mattress Topper is that it's free from polyurethane-based foams and uses responsibly-sourced materials with Global Organic Latex Standard (GOLS) and GREENGUARD Gold certifications.

However, I feel it would be very remiss of me not to point out some discrepancies between the website and the leaflet in the box.

In the leaflet, the mattress topper is billed as being Global Organic Textile Standard (GOTS) certified with no mention of the GOLS certification. It also describes the latex as the Talalay variety and mentions Fair Trade cotton, organic wool, and certifications from the eco-INSTITUT and Forest Stewardship Council.

The website's description, meanwhile, boasts about the GOLS and GREENGUARD Gold Certified only, so it's safe to assume the mattress topper has now switched to Dunlop latex as Talalay's production process means it's disqualified from a GOLS certification. (For more information on the differences between the two, take a look at my Dunlop vs Talalay latex breakdown.)

Eco-credentials and mattress certifications aside, this is still a sustainable, responsibly-sourced latex bed topper with premium, high-quality materials. While the the non-removable cover has no anchor straps and can only be spot-cleaned, this wasn't a deal breaker for me as it stayed clean and steady with a fitted sheet and a good mattress protector.

Birch Plush Organic Mattress Topper: Performance

• Expanded instantly with no chemical off-gassing
• Not plush, but still comfortable and supportive
• Breathable and moisture-wicking, but not cooling

I slept on a full-size Plush Organic Mattress Topper for two weeks, testing it with a focus on three key areas in line with our mattress methodology: support and comfort, temperature regulation and ease of set-up.

Set-up 

Like the best mattresses in a box, the Birch Plush Organic arrives at your doorstep compressed, rolled-up, and wrapped in plastic.

This makes shipping easier, but it does mean you'll need to unbox it and wait for it to expand — which is why it's strange that the leaflet in the box included no set-up instructions or expansion wait time.

As I've unboxed plenty of mattresses and mattress toppers in my time as a tester, I found the set-up to be pretty easy. (Although, the topper was plastic-wrapped extremely tight.)

However, If you're unfamiliar with the unboxing process, you may find it a little confusing without instructions via leaflet or website, so I suggest you checkout our guide on how to set up a mattress in a box.

It would have been nice to have an indication of how long it takes to expand as all bed toppers differ, but it reached its full height 10 minutes after unboxing. Even though you could probably sleep on the Birch topper straight away, I left it on the floor overnight before I slept on it, just in case.

Thanks to the natural materials, there's no nasty off-gassing you usually detect when unboxing memory foam toppers. Instead, you get the sweet, earthy smell of latex that's often compared to cupcakes or pastry dough.

Score: 4.5 out of 5

Comfort and support  

I put the Birch Plush Organic Mattress Topper on a the memory foam bed I tested for the EGOHOME Black 12" Memory Foam Mattress review. I genuinely liked the bed and even added it to the best cheap mattress guide, but a major complaint was that the slow-moving foam surface was difficult to change sleep position on.

Thankfully, the Birch Organic Plush Mattress Topper solved that problem with its quick-response spongy latex foam. It's responsive foam was flexible enough to give against my pressure points when side sleeping, but firm and durable enough to keep my back and hips upright and spine properly aligned when back sleeping.

Despite its name, however, this is not a plush mattress topper. Talalay latex is the plushest form of natural latex, but I doubt the Birch topper uses this anymore due to the GOLS certification (see the above Design & Materials section for more information on this) so can only assume it uses the firmer Dunlop.

Score: 4 out of 5

 Temperature regulation 

Latex is often boasted to be breathable and cooling, and while the former is true, the latter is more complicated.

While latex can boost airflow to help regulate temperature, it isn't cooling per se. This distinction was shown when I slept cool and comfortable during milder weather, but slept hot and humid during a heatwave when my bedroom was close to 85°F in the night.

Once testing was over, I switched my breathable non-cooling mattress protector with a cooling one (the one I reviewed for the Brooklyn Bedding Luxury Cooling Mattress Protector review 2025 in case you're wondering) and slept much cooler throughout the warm weather.

Score: 4 out of 5

Birch Plush Organic Mattress Topper: User reviews

The 1,500+ reviews on the Birch website for the Plush Organic Mattress Topper are mostly glowing, with an overall rating of 4.6 stars.

Positive reviews praise the great quality, support (some even claiming it alleviated their back pain) and balanced comfort that allows them to sleep on top of the mattress rather than sinking into it.

Only a small percentage of customers wrote a negative review, with the less favorable reviews mentioning that they thought it would be thicker and plusher.

While I have to point out that the 2" thickness is made clear throughout the website's description, I can see why customer's may be disappointed with the firmness considering "Plush" is in in the topper's title.

Should you buy the Birch Plush Organic Mattress Topper?

If you're looking for a high-quality mattress topper that uses certified-organic and natural materials, then the Birch Plush Organic mattress topper is a supportive, comfortable and relatively affordable option.

It supported me while both side and back sleeping, and gave me that bouncy easy of movement that you often can't get from even the best memory foam mattresses and toppers.

A queen may have a $399 tag, but it's still cheaper than some organic latex mattress toppers and beds on the market. Plus, the 100-night sleep trial and 10-year warranty is outstanding for a mattress topper.

That said, it's not as plush as the title suggests, so anyone looking to add super soft cushioning to a hard bed should look elsewhere. Also, despite its promise of a a cool night's sleep, the latex won't be cooling enough for those sleep chronically hot or experience night sweats.

Buy it if...

✅ You're eco-conscious: GOLS and GREENGAURD Gold certifications show that this mattress topper is sustainable and responsibly sourced.

✅ You hate that memory foam feel: While sink-in soft memory foam can give you that "quicksand" feeling, the latex foam is quick to bounce back after pressure is applied.

✅ You're a back, side, or restless sleeper: The spongy but firm latex supplies enough support for most sleep positions, especially back and side sleepers, and easy of movement for those who toss and turn.

Don't buy it if...

❌You're expecting it to be plush: Yes, despite its name, this is not a plush mattress topper. It's comfortable and supportive, but not super soft at all.

❌ You experience night sweats or always sleep hot: While latex is temperature-regulating, it's not cooling and no match against heatwaves.

❌You're on a budget: Despite it being relatively cheap compared to other latex toppers on the market, it's still premium priced and not for tight budgets.
