Obasan 9" - The Classic

1. Locate the cutter to unwrap plastic packaging. Carefully cut the bag using the cutter. Do this step slowly to ensure that the cutter doesn’t get caught in the organic cotton fabric. The mattress will slowly expand. Make sure no pets or kids around when opening your mattress.

2. Lay the cover over a foundation or solid-slatted base, so that the open end is at the head of the bed and the canvas (diamond pattern is on the bottom.) The Obasan logo should be on the left side and at the foot of the bed.

3. Pull all corners of the cover down over your foundation so that the cover is tightly wrapped around it like shown on the picture. When using a slatted base, just make sure the corners are fully stretched out ready for the rubber layers to be placed in it.

4. You will notice that each piece of rubber has a small label that identifies the firmness.

5. Start by placing the 3” firm base layer on the cover. Make sure that the rubber layer meets each corner of the covering and lines up with the foundation.

6. You may then place the 3” middle layer(s) right on top of the base layer. There are 2 separate pieces for each side of the bed for Queen, King and Cal. King size mattresses and only 1 piece for Twin, Twin XL and Double. Place the correct firmness on each side based on what your sleep expert has recommended.

7. The last piece will be the 3” soft rubber top layer. Always make sure that this piece is well aligned and nicely squared with the other pieces.

8. Once all the rubber pieces are layered, you may now pull the cover panels off the sides of the foundation and over the surface of the mattress.

9. Carefully check that the rubber layers are fully squared in each corner of the cover.

10. Now, pull the top of the cover tightly over the mattress. Start zipping each side of the bed while pulling down on the top of the cover to relieve stress on the zipper.

11. The two zippers should meet at the head of the bed.

12. Place your protector over the mattress, and you’re ready for your first nap!

Essential Organic Mattress Assembly Instructions

Before You Begin:

  • For Queen, King, and Cal. King sizes, you will have 2 separate latex pieces per layer (4 in total).
  • For Twin, Twin XL, and Double sizes, there is 1 piece per layer (2 in total).
  • Each latex layer has a fabric cover with the firmness labeled directly on it for easy identification.

Step-by-Step Assembly

  1. Lay the mattress cover on your foundation or solid slatted base.
    - Ensure that the open end of the cover is positioned at the head of the bed.
    - The canvas diamond-patterned fabric should face downward (this is the bottom).
    - The Obasan logo should be visible on the left side at the foot of the bed.

  2. Pull the corners of the cover down tightly over your foundation or base. If you’re using a slatted base, make sure the cover is evenly stretched out and ready to receive the latex layers.

  3. Identify the 4” firm base layer (the firmness is written directly on the fabric cover).
    - Place the firm base layer inside the mattress cover, ensuring it fits snugly into each corner.
    - For larger sizes (Queen, King, Cal. King), place one piece on each side.

  4. Next, locate the 4” medium firmness core layer (labeled on the fabric).
    - Place this layer directly on top of the firm base layer, carefully aligning the corners and edges.
    - Again, for larger sizes, install each side separately according to the firmness labels.

  5. Once both layers are placed and aligned, pull the side panels of the mattress cover up and over the latex layers.

  6. Ensure all layers are squared inside the cover, fitting tightly into each corner.

  7. Finally, pull the top panel of the cover over the mattress and begin zipping it closed.
    - Zip around the bed slowly, pulling the cover downward slightly as you zip to avoid stressing the zipper.

Tip:

If needed, adjust the layers as you go to keep everything aligned and squared inside the cover.
