⚠️ Handle with care when opening!
Your Polysleep mattress is tightly compressed using high-pressure hydraulic machinery.
Use the marked areas to open the box. Then use scissors to remove the plastic wrapping, but avoid knives or box cutters, as a sharp blade could easily slice through the foam.
Take your time — your mattress will unfold and be ready in seconds!
🛏️ Sleep on it right away
Once you remove the plastic, your mattress will expand almost instantly.
You can sleep on it immediately — there’s absolutely no risk of damage.
What foundation should I use with my mattress?
💤 Natural stabilization
The core of the mattress will take a few days to regain its full shape, stabilize and will reach its optimal firmness within about one week.
Your body may need up to 45 days to fully adjust to your new level of comfort and support.
Enjoy it from the very first night — comfort only gets better with time!
