Special Size Mattresses

Designers love us because we’re good at making custom sizes at a very reasonable upcharge. Custom-size mattresses in non-standard dimensions fit perfectly where a standard size mattress won't.

Berkeley Ergonomics Special Size Capabilities

Our all-latex mattresses are easy to adapt to virtually any size.

Our pocket coil mattresses are limited to reducing or enlarging the width and length of your custom mattress based on the diameter of each row of springs.

The mattress models listed in this collection are provided as popular examples of models we regularly adapt to custom dimensions.
