Divan bed for heavy person:
If you are planning on buying a divan bed because it is for a heavy person, then a divan bed may be a good choice for you since the divan bed has a sturdier build and base when being compared to other beds out there near around similar prices of a normal bed. A divan bed can take a lot of weight because the pressure is designed to be absorbed into the divan beds base so that it can handle heavier people on the divan bed.
If you need a large divan bed since you need the divan bed for a larger person since they would naturally be heavier since they are a larger person having a larger divan bed does not change the quality of the divan bed at all it just means that it will have more surface area for a person to sleep on. For example, you can buy a king size divan bed if you so need one and you can’t fit a different type of bed frame into the hallway to get the bed into the room.
If you need a divan bed for an extremely heavy person, the best chance you have is to find out if the divan bed base is made from metal or not. If it is not, then I do not think a divan bed would not be suitable since the divan bed does come apart if the mechanism keeping the divan bed together would fail.
For an extremely heavy person I would go for a bed frame that has a metal base and cushioning to make sure that it can handle the extra weight of the person on top and the chances that the bed frame would break after a couple of years would be minimal. Also make sure that the mechanism is made out of quality material and the bed frame has been manufactured by a reputable company so the chance of the bed frame breaking is really low.
