Simply send us your diameter
Who would’ve thought placing an order for a made to measure mattress could be so simple?
Our water tight, “dot the i’s and cross the t’s” approach lets you place an order with absolute confidence. Before we start making your new mattress, we’ll email you a clear drawing that shows exactly how your new mattress will be made. We’ll then eagerly await your reply with either the final go ahead or a list of changes that need to be made (although our drawings are usually pretty good first time around). We wont start manufacturing your mattress until you are 110% happy with our drawings.
Where possible, we like all measurements in centimetres, however if you still remember a time before the metric system then feel free to send your dimension in feet and inches.
