What arrives#

A roll-pack mattress arrives compressed, vacuum-sealed and rolled into a cylindrical cardboard box. A king-size mattress in a box is typically around 50 cm in diameter and 160 cm long — heavy (25–40 kg for a hybrid) but manageable by one person with a sack truck. It looks remarkably small for a full mattress.

Before you unbox#

  • Move the box to the correct room first — the box is easier to move than a partially expanded mattress
  • Have the bed base in position and the room arranged before opening
  • Get scissors or a box cutter ready
  • Having a second person makes the lifting significantly easier

Step-by-step unboxing#

  1. Open the cardboard box and slide the rolled mattress out
  2. Position it on your bed base in the centre, still rolled, aligned with the bed width
  3. Carefully cut the outer plastic film — the mattress will begin to unroll immediately. Cut shallowly to avoid cutting the mattress cover
  4. Unroll and lay flat on the base
  5. Cut the inner vacuum-seal film — air rushes in and expansion begins immediately
  6. Stand back and let it expand naturally

How long until it's ready?#

Most mattresses reach 80–90% of final size within 2–4 hours and are safe to sleep on after 4–6 hours. Full expansion to the stated depth typically takes 24–72 hours. The new foam smell (off-gassing) dissipates within 24–72 hours with adequate ventilation — open windows during and after unboxing.

If it doesn't expand properly#

If the mattress hasn't reached close to its stated depth after 72 hours in a room-temperature environment, contact customer service. Failure to expand is uncommon but can indicate a quality issue — most brands will replace a defective mattress promptly.
