The problem
A round bed is an impossible thing to shop for
There is no standard size, almost nothing is made for it, and a square mattress cut down is not the same as a mattress built round — it loses its edge support and its perimeter finishing.
We build round mattresses to the diameter of your bed, with the same handcrafted construction we sell in the showroom. We also build cut and radiused corners for beds that are not round but are not rectangular either.
Our standard round is 76 inches (193 cm) in diameter at $4,099. Larger and smaller diameters are quoted individually.

What we make
Round, oval and shaped
Round mattresses
Any diameter, built round from the start rather than cut down from a square.
Cut corners
Beds with angled corners, built to the exact profile of the frame.
Radiused and curved edges
Softened corners and curved footboards, where the mattress follows the frame line.
Oval and irregular shapes
Built from a template taken at the residence, for shapes that cannot be described in numbers.
Round bedding
Round beds need round fitted sheets, and almost nobody makes them. We carry fine linens and can source round and shaped bedding.
Every other custom size
European frames, yacht berths, oversized kings and antique sizes. See all sizes.

How to measure a round bed
- Measure the diameter across the widest point of the frame, where the mattress sits.
- Not the outside of the base, and not the headboard.
- If the shape is not a true circle, or the frame has a lip or a recess, we take a template at the residence.
- A template removes the guesswork — with a custom-size mattress there is no second attempt.

Questions
Round mattress questions
What size is a round mattress?
There is no standard. Ours starts at 76 inches (193 cm) in diameter and we build any size above or below that. Measure your frame rather than assuming a size.
Can you cut a regular mattress into a circle?
We do not. A mattress cut down loses its edge support and its perimeter finishing. We build the mattress round from the start.
Do you make oval beds and cut corners?
Yes, from a template taken at the residence.
Where do I find sheets for a round bed?
Through us. We carry fine linens and can source round and shaped bedding.
How long does it take?
7 to 15 days from the confirmed order.
Can it be returned?
No. A round mattress is made for one bed and is final sale.
Send us the diameter
Measure across the widest point of the frame, or book a time and we will come and take a template.
