A hybrid between our Suffolk and Oxford models, the Devon hybrid mattress features the support and durability of pocket coil springs, along with the customizable firmness and comfort of natural latex and wool. Hand-tufted and built in an English style, the Devon mattress is flippable and rotatable.

Perfect for couples, the dual-profile option allows each partner to choose the ideal firmness level for their side of the mattress, while the pocket coil springs help to minimize movement transfer.

See our Choosing a Mattress Guide for more details on how to choose a firmness, and to compare the Devon with other models. Not sure if you have the proper foundation? Check out our Choosing a Foundation Guide for more information.

Please note: the Devon is an ode to home; an exclusive model to Calgary and surrounding area. The Oxford is available Canada-wide.


The Devon comes in 5 firmnesses and for Queen and King sizes, it can be built dual-profile (where the two halves are different firmnesses).

*Be sure to select a firmness for each side when ordering a King or Queen bed. For Twin and Full mattresses, you must select the same firmness for both "sides", as they cannot be made dual-profile.

Case Material

There are two options for the case material of the mattress. Please note that the case might differ from the photos.

These are the standard case materials we use depending on the firmness chosen:
Soft & Medium-Soft: Tencel Top Case (first & second picture)
Medium, Medium-Firm, Firm:  Organic Cotton Herringbone Case (third & fourth picture)

Please let us know if you would like us to use a specific material for your mattress, otherwise we will go by the information provided above. If you have two different firmnesses, we will choose the case material according to the softer side of the mattress.


The Devon has a 12" depth.

We adhere to standard dimensions as much as possible. Please note the dimensions are give or take an inch, as our mattresses are handmade and materials can vary.

Twin: 75"L x 38"W
Twin XL: 80"L x 38"W
Full: 75"L x 54"W
Queen: 80"L x 60"W
King: 80"L x 76"W
Cali-King: 84"L x 72"W 


Pocket coil springs are the most popular with adults, as they provide ample support with some contouring effect (to ease pressure points), and minimize movement transfer between partners. *The King size Devon can also be built split into two separate Twin XL mattresses (2 half-Kings), which completely eliminates motion transfer.

100% Natural Talalay Latex is rubber from the rubber tree (Hevea Brasiliensis). Cradle-to-Cradle Gold, Oeko-Tex 100 (Product Class 1), and Eco Institut certified.

Natural Wool Batting

Please note that our materials can change over time so if you'd like to place a repeat order, we ask that you reach out to us to see if that product has evolved since you last purchased.

For more in-depth information, please visit Our Materials.


For longevity, this mattress should be flipped once every 4-6 months. We strongly recommend making sure you have the proper foundation to support your mattress. For more information visit our Choosing a Foundation page.

We recommend using a mattress protector to prevent spills and stains from damaging your mattress.

Perfect Mattress

I love this mattress so much. It's the right amount of supportive and soft which helps me have less hip pain at night as a side sleeper. I also got the pillows and they are a dream. Thank you!

Hi Dionne! Thank you for taking the time to leave us a review. Happy to know that the Devon is a great fit for you and that you’re getting less hip pain. Pillows are always the finishing touch to a good sleep. Wishing you the best sleep!

A Much Needed Upgrade

As new parents, we needed to get the most rest from what sleep we could get, and our new Devon mattress delivered! The firmness we chose has offered amazing support, highlighting just how much our old mattress was contributing to lower back pain that has since going away after the change. Our experience from the early discovery of Black Sheep to showroom visits and now to each night’s sleep was and remains excellent.

Hi Nikolas, thank you for your review! It’s so good to hear that you’re sleeping better now with the Devon. Glad we could also offer such great experience in the showroom, as well as with your sleep! Wishing you many nights of good rest!

I love my bed

With the issues that came after a car accident I knew I needed to replace my bed. I chose the firmest mattress available. It softened up a bit over the days now it’s perfect. I don’t have painful nights anymore. I sleep through most the night and well rested in the mornings. My Great Dane also enjoys the new bed :) The best part for me is that it’s built to last a very time.

Hi Maria, thank you for your kind words! We’re so happy to know that you’re finally getting the sleep you’ve been hoping for. We know it must’ve been hard! We wish you and your Great Dane many nights of restful sleep.

Tamara Wirth
Devon mattress

I ordered this mattress from Ontario without being able to try it first. I did this because after much research I knew this was the type of product I wanted. It is custom made, and natural products are used were applicable. No need for charcoal infused foam and cooling products when the real, authentic , natural products are used. I love my mattress. I get a fabulous night sleep. No more aching bones and sore backs. The staff is amazing. The company exemplifies how a company can, should and is run. A wonderful experience from start to finish with the Black Sheep Mattress Company!!

Hi Tamara! Wow, thank you so much for your kind words. We really want your experience to be amazing with our mattresses and our service, so we are so glad we were able to deliver on that part. Thank you for taking the chance on us and we hope you continue to have restful sleep.
