If you live in the United States or Canada, you are lucky to be able to choose from a handful of bedsharing mattress brands. They vary in design, size, and price, but any of them would make a fine family bed for your family.
The Top 4 Bedsharing Mattress Brands in the United States and Canada:
- Avocado
- Plank
- My Green Mattress
- Plush Beds
Your new mattress will need to be firm, flat, and level for your family now, and for the family a decade from now. Here are the top four bedsharing mattress brands.
1. Avocado is the Overall Best Bedsharing Mattress Brand
If you’ve been around here for a little while, you’ll know that Avocado is my favorite brand for bedsharing families like yours and mine. Throughout the years, we have tested and slept on five different mattress models and a dozen pillows. (Yes, really.)
This page goes lists my favorite Avocado products that have made my life as a cosleeping mom much easier.




This bedsharing mattress is the firmest mattress that Avocado has ever made.
It scores a whopping 10 out of 10 in firmness!
This will be especially helpful if you or your partner are large-bodied and you need an extra firm mattress to ensure that it doesn’t dip too low beneath you.
This gorgeous mattress is made up of two layers of 14-gauge coils plus high-density natural materials. This creates a solid, stable, and level family bed that resists sagging and delivers ergonomic alignment, even under large-bodied folks.
Keep in mind that more coils equal more support. The king-sized mattress features more than two thousand individually-wrapped coils! This improves responsiveness and pressure distribution.
As always, Avocado products are organic. In this case, it means that the surface of the mattress is naturally moisture-wicking, making it much more comfortable for the multiple warm bodies on the family bed!
When your baby is well into toddlerhood, and you don’t have to worry so much about the family bed being super firm, I recommend you add this mattress topper for more cushion.
Avocado is the best overall bedsharing mattress brand because it meets every single Cosleepy criteria: this model is firm, flat, level, and non-toxic.
What more could you ask for?
2. Plank is the Firmest and Flattest Bedsharing Mattress Brand

I dare you to find a firmer or flatter mattress on the market than this top-seller.
It isn’t suprising that it scores a 10 out of 10 in firmness, as it was designed to be the best of the best.
I like to think of this model as an updated, modern version of the tatami mat — which remains the standard for millions of family beds in Asia.
It is completely flat, containing just two layers of thick, dense foam. The foam is naturally cooling, thanks to open-cell technology that wicks away excess body heat.
Other than their clear safety benefits to cosleeping families, like yours and mine, firm mattresses reduce spinal stress, improve lumbar support, and alleviate back pain. Good to know that this mattress will continue to support your body after your bedsharing days are gone!
At that point, if you’re tired of the extreme firmness, I recommend that you flip it over to the other side. The other side is designed to be medium-firm. (And plus, flipping the mattress is always great for airing it out and extending its longevity.)
Either way — Plank is the firmest and flattest bedsharing mattress brand you’ll be able to find in the United States or Canada.
3. My Green Mattress is the Most Affordable Organic Bedsharing Mattress Brand

If buying an organic mattress is important to you, consider My Green Mattress alongside Avocado. This model is the most affordable organic mattress you’ll be able to find.
It scores a 7.5 out of 10 in firmness. It will probably barely pass the Cosleepy Mattress Firmness Test, but it is not nearly as firm as the Avocado or Plank mattress models, above.
This mattress features three inches of organic Dunlop latex, cotton, and organic wool. Wool is always a bedsharing family’s dream — it is naturally cooling and moisture-wicking!
Remember, more coils mean more support! This model has more than 1,400 pocketed coil springs and a 7-zone lumbar support system.
Of course, all mattresses from My Green Mattress are green, wink wink. This one is GOTS and GOLS certified and free from flame retardant chemicals, polyurethane foams, and fiberglass.
I think that your baby deserves to spend more than half of their life on a non-toxic mattress! If you agree, My Green Mattress is the most affordable organic bedsharing mattress brand out there.
4. PlushBeds is the Best Bedsharing Mattress Brand for Your Partner

It’s hard enough for us moms to sleep on an extra firm mattress for this season of life, but what about our partners? If you have a partner who wants or need a softer mattress, look no further.
Consider ordering this firm model with dual firmness!
If you order a Queen, King, or California King, you can “split” it. This means that you and your baby can cosleep on the medium-firm side while your partner sleeps on a medium side!
(Quick note from the Cosleeping Safety Captain: If there is a gap between the two sides, be sure to pack it underneath the fitted sheet!)
The medium-firm scores an 8 out of 10 in firmness. No, that’s not the firmest model we’ve discussed today, but you can call Plush Beds customer service to request a custom firmness!
It features the highest quality GOLS certified organic latex, GOTS certified organic cotton, and GOTS certified organic wool. It is also GREENGUARD Gold certified!
I am also a big fan of this bedsharing mattress brand because they offer an extra-firm latex mattress topper. This is a great option if your current mattress barely passes the Cosleepy Mattress Firmness Test and you want to make it a little bit firmer with a topper.
Plush Beds is the best bedsharing mattress brand for partners because they offer dual firmness options! Not everyone in the family has to suffer!
