Bamboo Rattan Chaise Lounge Wrought Iron Steel Spotted Bench Couch - Help Identify Please

I have searched for similar all over the internet and cannot find anything so any help would be much appreciated!
I purchased this Chaise Lounge at an antique store. The owner insisted it was Spotted Bamboo that was split for weaving. The main frame I think is wrought iron and very heavy but it could be steel. It is wrapped in what the previous owner said was split spotted bamboo.
Almost mint condition except for a few small pieces of the weaving broken.
I am not sure if it is genuine bamboo or fake or not bamboo at all but rattan. I notice there are spots all over the bamboo except for the underside (but not sure if the bamboo was split for weaving if that would be normal for the underside to not be spotted if it is genuine).
It is approx. 5 ft long, 3 ft tall and 2 ft across including arm rest.
Some of the frame seems to be solid spotted bamboo or a replica of bamboo.
