1. Remove The Packaging
Your mattress arrives in fully recyclable paper packaging. No sharp tools are required. Simply locate a natural opening in the paper and gently tear it open, similar to unwrapping a gift.
Open slowly and allow the mattress to expand fully. Please ensure pets and children are kept at a safe distance during this step.
2. Prepare The Mattress Cover
Twin & Twin XL Mattresses
Twin mattresses arrive fully assembled inside of the mattress cover.
When the Obasan logo is facing up, the mattress is configured with:
- Firm layer on the bottom
- Medium layer on top
This is the recommended configuration for children 6 years and older, or based on personal preference.
If your child is under the age of 6 or for a Firm Set Up, flip the mattress so the Obasan logo is upside down.
Double & Queen Mattresses
- Each latex layer includes a small label indicating its firmness. Take a moment to confirm the correct placement before assembling.
- Lay the mattress cover over your foundation or solid slatted base with the open end at the head of the bed. The canvas side with the diamond pattern should face down. The Obasan logo should be positioned on the left side, at the foot of the bed.
- Next, pull all four corners of the cover down over the foundation so it fits snugly. If you’re using a slatted base, ensure the corners are fully stretched and ready to receive the latex layers.
3. Assembly Your Latex Layers
For Kids Ages 6+ or For A Medium-Firm Set Up
- Start by placing the 3" Firm base layer into the cover first. Ensure it's fully squared, reaching each corner and aligned with the foundation.
Double mattresses include one single piece. Queen mattresses include two separate pieces of latex to be placed on each side of the mattress cover.
- Next, place the 3" Medium core layer directly on top of the firm base layer.
Double mattresses include one single layer of latex. Queen mattresses include two separate pieces (one per side).
For Kids Under 6yo or For A Firm Set Up
- Start by placing the 3" Medium base layer into the cover first. Ensure it's fully squared, reaching each corner and aligned with the foundation.
Double mattresses include one single piece. Queen mattresses include two separate pieces of latex to be placed on each side of the mattress cover. - Next, place the 3" Firm core layer directly on top of the firm base layer.
Double mattresses include one single layer of latex. Queen mattresses include two separate pieces (one per side).
4. Close The Cover
Once all latex layers are in place, pull the side panels of the cover up and over the mattress surface.
Carefully check that all layers are fully aligned and neatly squared in each corner of the cover.
Pull the top panel of the cover tightly over your mattress. Begin zipping from both sides, gently pulling down on the cover as you go to reduce tension on the zipper. The two zippers should meet at the head of the bed.
5. Protect Your Mattress
To protect your child's mattress and extend its lifespan, we recommend using a mattress protector.
Add your sheets, and your child is ready to enjoy a healthy and comfortable sleep!
