Customize your mattress

Each layer of natural latex can be ordered soft, medium, or firm. You can then decide whether you’d like solid layers of latex, or whether you’d like it split down the center to allow for different firmness on each side of the mattress. Many people prefer to place the softer layers of latex on the top with the firmer layers toward the bottom. But the options are endless, and it is entirely up to you! We recommend that customers choose layers softer than they might expect to like. Once you receive your mattress, if it feels too soft, you can alternate layers. Simply move the softer layers down in the mattress and move firmer layers up to discover your personal ideal in comfort and firmness level. For example, if you choose the following layers (in top-down order) soft, medium, and firm and the mattress feels too soft, simply flip-flop the second and third layers so you end up with soft, firm, and medium.

Solid or Split layers?

Some people wonder if the split in the latex can be felt. The good news is that we have constructed our organic mattress to have a seamless feel in the middle. Though you will notice the difference between a soft and a firm, there will certainly not be a hole or gap in the center of your bed. If you are concerned, you could choose a solid layer of latex for your top layer and then choose split layers for the bottom 2 layers.

Your mattress, your design!

All mattresses include a zipper on the bottom, offering you maximum flexibility. Since your mattress was designed by you, we think you should be able to change and adjust it too! Once you receive your organic mattress, the latex can be placed (in any firmness combination) into the organic cotton and wool cover, and zipped up.

What should you place the mattress on?

A Bella Sera organic mattress should be placed on a flat surface, ideally, a platform bed or wooden slat foundation. We prefer slats so that air can flow beneath the mattress, slats should be no more than 3.5″ apart. A platform bed frame, is perfect for this mattress, which eliminates the need for a box spring or foundation.

Bella Sera Set

Pair your Bella Sera Nove 3 organic mattress with a Platform Bed Insert which will replace a boxspring or foundation. This unupholstered Platform Bed insert allows you to convert your traditional bed frame into a platform bed. This solid wood insert features tool free assembly, maple hardwood and poplar slats. The Platform Bed Insert is an either five OR seven inch tall insert designed to fit in a traditional bed frame, replacing a box spring or foundation. Slats are 3 inches wide and spaced 2.5 inches apart. Featuring solid maple construction and fourteen poplar slats, the wood is finished with a fine sanding and no coatings resulting in a zero VOC product. This frame provides support and breathabilty for your mattress while the simple construction allows for tools free assembly for easy shipping and moving.

Once your mattress arrives

Latex mattresses are very heavy and can be quite awkward to move. Whereas innerspring mattresses have a rigid, easily movable structure, latex is flexible and, well, droopy! It is quite challenging for us to move a king- or queen-sized latex mattress without two or three strong individuals. Even then, it can be a challenge to grasp the mattress to move it without ripping the organic cotton and wool cover. If we were to ship your mattress completely assembled, the latex layers would shift and bunch up inside, making it necessary to unzip the casing and realign your latex layers anyway.

To prevent the bunching up of your layers, we ship our mattresses in separate parts: Your casing is shipped separately from your latex layers. Once your shipment has arrived, lay out the casing on the foundation or bed frame; align it; and unzip the top portion of the casing from the bottom portion of the casing. Begin layering the latex on the bottom of the casing until the layers are in the preferred order. Place the top of the casing over the latex and zip up the mattress. You will receive more detailed instructions with your shipment. If you feel you may be unable to assemble your mattress properly, please contact us for different shipping alternatives.


I’d like to share with you how pleased I am with the Bella Sera Nove 3 full mattress I recently purchased for my granddaughter. This is the third organic mattress I have purchased and the one I am most pleased with. The 3 layer system is a great. The firmness is just what we wanted and I received so much help from your staff in making our final decision. The next purchase will be an organic mattress for my grandson, and I look forward to contacting The Natural Sleep Store again. Thank you for a wonderful product and a very pleasant shopping experience!

We have had this mattress for a little over a year now. It is incredibly comfortable and durable. Our son jumps on it all the time and it holds up well.

I’ve been meaning to email you for what feels like months, but we love LOVE love our bed. T. has completely come around to the king size too. =) But the latex mattress is phenomenal. T. was traveling for work and he could not believe how much he missed our new bed.
I did want to mention one specific thing, T. keeps remarking at how much he likes not having a “seam” along the edge of the mattress. So I glad we went with the Bella Sera.
And the wool comforter has been the perfect weight/warmth for us too. No need for extra blankets. We just have a flannel duvet cover and it’s plenty warm.
Thanks again for all your help, and patience!
