Expert Review:
Calla Firm - A Traditional Firm Mattress

The Calla firm double sided mattress from Restonic is a must-have for anyone looking for a comfortable and supportive night's sleep. The attention to detail in the construction of this mattress is evident from the moment you lay down.
The quilted cover, with its flanges and side handles, not only looks great but also makes it easy to handle and move the mattress. The use of Airflow FR fiber in the cover ensures excellent breathability, keeping you cool and comfortable throughout the night.
The top side of the mattress features 1.5 inches of comfort foam and 1 inch of extra firm foam, creating a plush and supportive sleeping surface. The core of the mattress is made up of a 1-inch densified polyester pad, a 416 tempered 13 gauge Bonnell innerspring with 6 gauge border wire, and another 1-inch densified polyester pad, all working together to provide the support you need.  The bottom side of the mattress features same as the top so it can be flipped with a 1 inch of extra firm foam and 1.5 inches of comfort foam.  This provides a solid base for the mattress and helping to prevent sagging over time.
In conclusion, the Calla firm mattress from Restonic is a top-quality mattress that offers the perfect balance of comfort and support. The attention to detail in the construction and the use of high-quality materials make this mattress a must-have for anyone looking for a good night's sleep. Order yours today and experience the comfort and support for yourself!

Measure all 4 sides of your mattress and bed frame before ordering.
We recommend you order the mattress 1 inch smaller than the space it is meant to fill. This will leave extra room for sheets, blankets, and variations in production size. Some people like a larger gap to really have room for your hands to reach down and change sheets easily. Please note that production size is not guaranteed to be exact.

Common Questions About Ordering Custom Size Mattresses

What if it doesn't fit?
We will never ship out a custom mattress or boxspring that exceeds the size you have ordered without contacting you first to check if the size variance 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 in the corners for boards or bolts that often protrude in to the mattress area, and order your custom mattress and custom boxspring small enough to fit inside of these protrusions.
What sizes are available?
Any custom size is available upon request but with most models you are limited to being smaller than a King mattress. If you need a custom size bigger than a King, here are some models that can be supersized. If you don't see your size listed, please call us to find out what prices would be.
Can I really order any size and shape?
Yes, we are able to make some of our models in odd shapes (like cut or rounded corners) for antique beds, RVs, and even boats; however most of them can only be done in a 4-sided rectangle. Here is a model that can be made in any shape. You can call us to order by phone, or just select your approximate size, place the order online, and we will definitely give you a call back to discuss you exact shape before we start building anything.
We recommend you order your custom mattress 1-2 inches smaller than the space it is meant to fill. This will provide extra room for tucking in sheets and blankets.
Our online shopping lets you select a model to the nearest inch but most of the time we can even do half-inch increments for a perfect fit. We call ALL of our online buyers before we start building anything. This allows us to discuss your exact size and make changes before production begins. This lets you buy online now without fear of getting the wrong size.
What about the boxspring ?
It is very important to measure the size of your box separate from your mattress because in many older bed sets, the box was made slightly smaller than the mattress. The length and width of a solid foundation boxspring can be custom made to fit exact dimensions. The thickness can not be customized but boxes are available in several standard thicknesses ranging from 2-9 inches.
How soon will my custom size mattress 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 then begin and usually takes 1-3 weeks. After production, the custom mattress will be packaged at the warehouse to protect it during shipping to your home. Shipping takes 2-10 days depending on the destination city. The combination of producing, packing, and delivering means that you should receive your custom mattress within 2-6 weeks of the day you order. If you need a more accurate estimate, or have a quicker deadline, please give us a call to discuss expediting options.
