If you don’t want a lopsided or uncomfortable bed, you need a mattress from a custom mattress factory that will fit your bed frame. In most cases, that’s as easy as buying a standard twin, full, queen, or king size mattress.

But if you have an antique, custom, or otherwise non-standard bed frame, finding a mattress that fits correctly can be a challenge. Most mattress stores don’t sell anything outside of the standard sizes. And while a custom mattress factory can probably help, you need to know what dimensions you need — which is especially hard if your bed frame is an unusual shape.

At Slumber Ease, we’re here to help with mattress challenges. We can help you measure your bed frame to ensure a perfect fit from your new custom mattress. Whether you have a non-standard bed frame, a sleeping area in the V-berth of a boat, or another unconventional bed shape, we’ve got you covered.

Measuring a Rectangular Bed Frame

For most homeowners with rectangular bed frames, measuring for a custom mattress is relatively straightforward. Follow these steps to accurately measure your bed frame:

  • Length: Measuring the length of the bed frame from the headboard to the footboard. Place your measuring tape or ruler against the inside edges of the frame to get an accurate measurement.
  • Width: Measure the width of the bed frame from one side to the opposite side. Again, you should measure from the inside of the frame, not the outside.
  • Depth: Some bed frames have sides that extend above the slats or foundation, “framing” the mattress to help keep it in place. If you have this kind of bed frame, you should measure the depth of those sides. Measure the distance from the top of the slats or foundation (not the floor) to the top of the frame sides. While your mattress doesn’t need the same depth measurement as the frame, you likely won’t want it to be shorter.

Keep your measurements in either inches or centimeters for consistency, not a mix of both. Once you have these measurements, you can give them to a custom mattress factory. The company can use them to build a mattress that fits your bed frame well.

Measuring Odd Mattress Shapes

If you have a rounded, oddly angled, or unusually shaped bed frame, measuring will be a little more complicated. Here are a few tips to help you get the measurements the mattress factory will need.

Contact a Custom Mattress Factory. The staff can give you tips on how to measure your bed frame. They can guide you through the process and ensure you get the kinds of measurements they need, including the shapes of rounded edges or odd angles. They may need you to make a template, but they will tell you how to do so.

Measure Key Points. Measure the length and width at the widest and longest points of the frame, as well as the shortest points. If you have a round mattress, measure the diameter and circumference. Take multiple measurements to ensure accuracy.

Take Pictures. Pictures of the bed frame (with and without your current mattress) will help the mattress factory build the right shape. They will also help the factory staff check that they aren’t missing key measurements or shape oddities.

With precise measurements and a template made as directed by the mattress factory, you can get a custom mattress that matches your bed frame. A well-fitting mattress will give you better comfort and support.

Whether you have a standard rectangular bed frame or an unconventional shape, Slumber Ease Mattress Factory is here to help. We work with many unique mattress shapes, dimensions, and requirements. Our expertise will help you get a custom mattress that properly fits your sleep needs and bed frame.
