Clearwater Medium mattress

“A medium mattress with excellent support from a coil system that runs edge-to-edge and features stronger coils at the perimeter. Above the support system is 1.5" of medium, high-density upholstery padding. Firmness from the steel coils is paired with the softer padding on top, creating a balanced feel. This is a great choice for sleepers that are seeking a high-quality, medium level mattress, and prefer spending a bit less for a mattress without memory foam or latex.”

    Steel Support System


    • 6", 'Quantum Edge Elite - Bolsa' support system
    • 15/16 gauge steel (15 in sleeping area, 16 around edge)

    • Made in USA by Leggett & Platt.

        What you'll notice:
        Very supportive feel with just the right amount of conforming effect. Low motion transfer, which allows partners to remain undisturbed when changing sleeping positions. Firmer coils around the edge, which eliminates premature wear and "roll off" effect.

        Comfort Layer

        High-density padding for cushion top

        • 1.5" of medium, 1.8 LB upholstery padding
        • Heavier weight = higher quality

          What you'll notice:
          Gel-infused quilt padding will dissipate heat faster than regular foam. The plushness of comfort layer yields a nice cushion and balances out the firmness of the coils.

          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".

          Great mattress and foundation, terrific service and support

          I had great trepidation about opredering a new foundation and mattress for an very old bed, but Custom Mattress Makers talked me through all the issues, made timely delivery, and included detailed and clear directions with each piece. The pieces themselves were in excellent condition and fit the bed perfectly. I would highly recommend Custom Mattress Makers to anyone who is looking for a new vfoundation or mattress.

          Great workmanship, excellent product.

          After reviewing online and submitting questions via email, we decided to order our custom mattress with Custom Mattress Makers. Once the order was submitted, we were notified it was in process, and within 7 days it was shipped to us. Couldn’t be happier with the quality and comfort as well it fitting perfectly in the space we had built. Thank you all so very much for such an impressive mattress! We won’t hesitate to recommend your products and services to others.

          Thank you so much for a comfortable, affordable mattress that fits my 100 year old bed perfectly. You are terrific. I will certainly be getting mattresses for my other beds from you as well. It was very easy to install. Lovely.

          Great mattress!

          We love our new mattress! Arrived early, perfect fit and very comfortable!

          So Far So Good!

          We purchased 2 custom twin mattresses for our Class C Sprinter Chasis RV, 72" x 30". They came as promised UPS, we rolled them out on the platforms gave them the instructed 24 hours to settle after shipping then used them last night on our first camping trip since purchase. We both woke up feeling great after all the other trips sleeping on what came with coach which equated to a chaise lounge cushion. More than I was hoping to spend but a good night sleep was well worth it. Now the test will be how well they hold up with time.
