You may not have a door that can accommodate your couch. We have years of experience in hoisting furniture up or down buildings and apartments. All goods are wrapped prior to the hoist to ensure no scratches or marks. Attached is a picture of a coricraft couch being hoisted up 8 floors. This is a technique that not just anyone should attempt.
We take proper measures to ensure that there is no damage to the item of furniture but more than that, we ensure the building is not damaged or vandalized in the process. We have years of experience in doing this so leave it to the professionals.
