Looking for a sophisticated alternative to a box spring? Our Classic Base is upholstered in an organic cotton canvas fabric, with a clean, minimalist design. Built from solid wood with a slatted surface on top, for maximum breathability and moisture flow.

This versatile base can be made to stand alone with wood legs, or made without legs to be dropped into an existing frame (to raise the height of the mattress).

Not sure if the Classic Base is right for you? Read through our Choosing a Foundation Guide for more information.


While heights of 4" or 8" are pretty standard, we commonly build our bases anywhere from 3" to 10" in height. Please contact us for a custom height or leave a note on your order.

You can choose to add legs for a stand-alone base. The round legs will add 5" to the height of the base and the square legs add 6". Stand-alone bases are made to standard dimensions:

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

Alternatively, you can choose to add no legs, if you want to use the base like a box spring, inside of an existing frame. In this casewe require the internal dimensions of your frame. Please read through our Choosing a Foundation Guide for more information on how to measure your frame.

Please note: our King bases are always built split (in two halves) for ease of use when moving. As they are split they require double legs at a cost of $150.00 for the set.


    Our bases are made from solid wood and upholstered in 100% organic cotton 10oz canvas fabric (GOTS certified).

    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.

    Everything needs a good base

    I may not feel the base but I do realize this mattress is unique so I purchased the full set together. I wanted to make sure my mattress could breathe and have a strong support as it’s very thick and heavy. It compliments the mattress with a perfect fit and a natural simple look. The delivery was smooth and the guys were very nice. Took my old bed away which was a huge bonus for me. The all around service, start to finish was great.

    Hi Maria! The classic base was a great choice for a sturdy and breathable option. So glad we were able to get that base to you smoothly and get your old mattress away. It has been lovely to work with you!

    Bed base perfect size

    We had to get a thinner bed base and it made no difference whatsoever in the comfort of the bed. 5 stars for Black Sheep Mattress for product and service quality.

    Thank you! Glad to have built you a great base for your bed. Thank you for supporting our small business!

    Glad we purchased this essential Piece

    All I can say is good things about this company. We originally just bout the mattress to use on our existing frame but soon realized our fancy frame was not built well to support the king mattress. Black Sheep came and customized the base to fit within our existing frame and it turned out amazing. It also stiffened up the mattress they way it should have been. These guys are amazing and top notch customer service.

    Thank you for taking the time to write us a review, Mark! We're glad that we were able to get you fitted for a more supportive foundation while still keeping your existing frame! Mattresses that don't feel quite right are very often caused by a weak foundation-- we see it all too often! Thank you choosing to support local and it's been a pleasure working with you to find your perfect sleep solution!


    It's made all the difference to our mattress. Our mattress was uneven because our base was sagging! New king base and voila! The mattress is perfect and we're having great sleeps. Awesome company, awesome product, awesome service. Thanks so much!

    Thank you for the review, Oliver and Elysa! We're happy to hear that your bed issues have been resolved by changing out your old boxsprings to one of our bases. The foundation that the mattress sits on surprisingly plays a big part in the comfort of your sleep. Happy sleeping!

    Beautiful Bed Base

    Thank you Black Sheep Co for making a beautiful bed base to match with a beautiful mattress. Strong, sturdy and easy to assemble the legs (no tools required). I especially like the look of it, classic and elegant. PS-if Black Sheep co. ever start making proper couches, they have a customer in me :)

    Hi Sennait, thank you for the wonderful review! And yes, we would love to get into making couches! So far we've done some couch cushions but we're hoping to one day be able to build and upholster a whole couch. Take care!
