Boxes can be bought at a slight discount when combined with a custom mattress. Just select the boxspring option on the 'more info' page of the mattress.


Solid Wooden Boxsprings

This is the most common type of mattress foundation used today. The solid wooden construction gives strong support that will not bend or flex. Their simple design is lightweight and inexpensive.

Need a mattress too?

Your foundation may be cheaper when you buy it with the mattress, depending on shipping method needed. Instead of adding your boxspring to the cart now, first find your custom size mattress, click "more info" and just select the boxspring option to get it for the best price. If you need the foundation to be a different size than the mattress, please add notes during checkout in the cart, or call us to place your order over the phone.


Measure all 4 sides of your bed frame before ordering.
Be sure to look for boards and bolts that may protrude into boxspring area and order your box small enough to fit. Do not try to order a tight fit because it may be hard to place into the bed. All of our boxes are hand made so the sizes will vary a bit from what is ordered - sometimes smaller but usually a bit bigger. Most beds do come within 0.5 inches of the requested size but we recommend to order the boxspring 1 inch smaller than the maximum to avoid fitment issues.


Common Questions

What if it doesn't fit?
We will never ship out a mattress that exceeds the size you have ordered without contacting you first to check if the extra size will cause an issue. Since these are custom made for you they can not be returned, so please be careful when taking measurements. On some bed sets, the box spring will be a different size than the mattress so you will need to measure both pieces. Also, since beds are often set up not perfectly square, you will need to measure all four sides of the bed to find the correct size. Be sure to check for boards or bolts that might protrude in to the mattress area and order your pieces small enough to fit inside of these protrusions.
What sizes are available?
Any size is available upon request but with many models you are limited to being smaller than a King mattress. This is because the mattress will be made by taking the King and shortening it. With some innerspring models, multiple coil sets can be combined to exceed King size but that is not possible on all models. It is easier to make an oversized memory foam model. If you need an odd size bigger than a King, please call us to find out what models are available.
Can I really order any size and shape?
At this time, we only distribute 4-sided rectangular mattresses with no special notches cut from the corners. The size can be as large as a king, so up to 76" wide and up to 84" long. If you need an odd size bigger than a king, please call us to find out what models are available. You can also order a custom mattress small enough to fit in a baby's crib. Mattresses are formed by rows of metal springs and since springs cannot work if cut in half, your mattress core will be sized in 1-2 inch increments. This means that if you order 47x63 it will be built between 46x62 to 48x64 but most of the time it will come within 0.5 inches of the requested size. Please let us know how precise your size must be.
How soon will my box arrive?
Once your order is paid for, a specialist from Michigan Discount Mattress will call you on the phone to verify your sizes and delivery information. Production will begin and usually takes 3-6 days with some going faster and others taking a few days longer. After production, the mattress will then be packaged at the warehouse within 48 hours to protect it during shipping to your home. Shipping takes 2-8 days depending on the destination city. Deliveries to the eastern USA are usually faster but packages will sometimes make it all the way to the Pacific coast in only a few days. The combination of producing, packing and delivering means that you should receive your mattress within 1-4 weeks of the day you order. Our streamlined process has successfully delivered 90% of our orders within 3 weeks.
