Clearwater Firm mattress


A high-quality, "classic" firm mattress for a great price. Excellent support from a coil system that runs edge-to-edge and features stronger coils at the perimeter. Above the support system is a layer of firm, high-density upholstery padding, which lays the body nice and flat. The top fabric is custom quilted, which provides a small amount cushion to balance out the firmness of the layers underneath. Not as hard as a board, but a majority of individuals would agree this is a firm mattress.

          Odd/Custom Size Mattress Variance

          Due to coil barrel diameters, all custom/odd-size mattresses are subject to up to a 1" variance in each direction.

          • As skilled as our craftsmen are, it is impossible to construct a spring mattress to the exact dimensions of all size combinations. Each coil spring has a predetermined diameter, therefore we are somewhat limited when it comes to the width and length of the mattress.  Since we cannot split a coil in half or thirds, we build the mattress to within a 1" variance of requested dimensions.
          • In most cases our mattresses are very close to perfect. However, these restrictions do exist and it is completely normal to see your mattress slightly smaller or larger than ordered.
          • On the Cart page, there is a box where you can request the mattress to be made "slightly undersize" or "slightly oversize".

          Could not be more pleased

          The mattress was delivered on time and to the exact dimensions ordered. It is superbly comfortable. The instructions for properly unpacking the mattress were appreciated. But what really stood out was the communication with Custom Mattress Makers before I even ordered. Jake answered within a day every question I had, and I sent multiple emails with multiple questions. It was clear from his replies that he really read what I wrote. I rarely come across anyone who communicates that well. I recommend the company without the slightest hesitation.

          Perfect fit

          Everything came pretty quickly and was exactly as I specified. Customer service was excellent.

          Michael G. (Charlotte, NC)

          Easy to deal with CMM team. Accurate results for the custom shape of the mattress. Stayed in contact with me. Received exactly what was expexted, on time. Fit just as intended. After a few days of getting accustomed to the new mattress I slept soundly through the night. I couldn't ask for more!

          Good Sleep

          The packaging was exceptional. The vacuum sealer must be HUGE! All instructions were spot on. The opening process was just as you said. In just 3 hours, the mattress was ready for sleep. My wife cannot say enough about the cumfort.

          Extreme Comfort

          After a month with our split mattress and foundation I'm still amazed how comfortable it is! Hands down the best we've ever had and finally the right fit for our European frame. Makes all the difference. Don't hesitate--great quality, great personal customer service and the best night's sleep you can get!!

          Score on having a custom mattress made!

          I needed to order two custom mattresses for a 1960 twin bed corner set, I initially ordered two new mattresses from a mattress store only to discover the size was all wrong for my vintage set. When the replacement custom mattresses arrived they were perfect. I highly recommend the Custom Mattress Makers when in need of a custom or off sized mattress.


          Great customer service. Shipped fast, comfy mattress

          New bed, new comfort.

          In the process of updating our 2006 Fleetwood Discovery we removed to hide a bed couch, which was not very useable for us. I built a bed frame with a platform lift to access storage space under the bed. I ordered a custom size Daytona firm mattress. It arrived the day I finished the bed frame. It is firm and very comfortable. We now have a daybed that serves as a couch and a comfortable bed. We are very pleased.
