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 components to expand fully. Please ensure pets and children are kept at a safe distance during this step.
2. Prepare The Mattress Cover
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 be face down. The Obasan logo should be positioned on the left side, at the foot of the bed.
Pull all four corners of the cover down over the foundation so it fits snugly, as shown in the reference image. If you're using a slatted base, ensure the corners are fully stretched and ready to receive the latex layers.
3. Prepare Your Base Layer(s)
Each latex layer includes a small label indicating its firmness. Take a moment to confirm the correct placement before assembling.
For a Medium-Firm Set Up:
Start by placing the 4" Firm base layer into the cover first. Ensure it is fully squared, reaching each corner of the cover and aligned with the foundation.
- Queen, King, and California King mattresses include two separate pieces (one per side).
- Twin, Twin XL, and Double mattresses include one single piece.
For a Firm-Medium Set Up:
Start by placing the 4" Medium-Firm base layer into the cover first. Ensure it is fully squared, reaching each corner of the cover and aligned with the foundation.
- Queen, King, and California King mattresses include two separate pieces (one per side).
- Twin, Twin XL, and Double mattresses include one single piece.
4. Prepare Your Core Layer(s)
For a Medium-Firm Set Up:
Next, place the 4" medium firmness core layer(s) directly on top of the base layer.
- Queen, King, and California King mattresses include two separate pieces (one per side).
- Twin, Twin XL, and Double mattresses include one single piece.
For a Firm-Medium Set Up:
Next, place the 4" firm core layer(s) directly on top of the base layer.
- Queen, King, and California King mattresses include two separate pieces (one per side).
- Twin, Twin XL, and Double mattresses include one single piece.
5. 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 latex layers are fully aligned and neatly squared in each corner of the cover.
Pull the top panel of the cover tightly over the 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.
6. Protect Your Mattress
To protect your mattress and extend its lifespan, we recommend using a mattress protector. Add your sheets, and you're ready to enjoy a healthy and comfortable sleep!
