2. Istruzioni per l'installazione
Your Serta Sleeptrue mattress is conveniently compressed and packaged in a box for easy delivery. Follow these steps to set up your new mattress:
- Step 1: Remove from Box. Carefully remove the rolled mattress from its shipping box.
- Fase 2: Unfurl. Place the rolled mattress onto your desired sleep platform (e.g., bed frame, adjustable base). Carefully unfurl it, ensuring it is centered.
- Step 3: Expand. Remove the plastic wrapping. The mattress will begin to expand immediately. Allow up to 72 hours for the mattress to fully expand to its intended size and firmness. Initial off-gassing is normal and will dissipate within one to two weeks.

5. Manutenzione e cura
Proper care will extend the life and maintain the quality of your Serta mattress:
- Coprimaterasso: Per proteggere il materasso da macchie e versamenti e per preservarne la salute e la durata, consigliamo vivamente di utilizzare un coprimaterasso.
- Pulizia: For soiled areas, apply baking soda and let it stand for approximately 15 minutes. Then, vacuum the area and repeat as needed. Ensure the product is aired out as much as possible.
- Evitare i liquidi: Do not apply liquids directly to the mattress. Liquids can stain the fabric and potentially worsen soiled areas. Moisture or chemicals applied directly can cause premature breakdown of the foam and damage the product.
6. Risoluzione Dei Problemi
Ecco le soluzioni ai problemi più comuni che potresti incontrare:
- Odore del materasso nuovo: It is normal for a new mattress to have a slight odor upon unboxing. Please allow one week of use for your mattress to air out and for the odor to dissipate.
- Espansione incompleta: While the mattress expands quickly, full expansion can take up to 72 hours. Ensure it is placed on a flat surface in a well-ventilated room during this period.
