"Adelia" spring mattress Firm comfort The Adelia First spring mattress is equipped with 884 pocket springs and 25 km/m³ polyurethane foam. Wrapped in 100% polyester ticking, this mattress offers you a firm sleeping surface and quality comfort. Such sleeping quality is perfect for people looking for well-balanced bedding that does not sink with each pressure exerted. Sleeping independence Because they are individually wrapped, each spring has its own autonomy which prevents pressure exerted on one from affecting the other. The advantage of such technology is that you will no longer be woken up in the middle of the night by your partner's movements. These will be isolated and you will be able to sleep peacefully. Health benefits The pocket spring technique also provides effective support for your entire body. In particular, your usual pressure points will be reduced, allowing you to easily find a comfortable sleeping position.
