Hi orkan,
I hope so too but as you mentioned some people are more sensitive than others so it can take a little longer (and it can also vary from mattress to mattress as well) but the smell should be gone soon.
The use of lower quality and less durable materials is certanly an issue in the industry but the good news is that the Tuft & Needle uses good quality materials and there aren’t any lower quality materials or weak links in the mattress that would be a cause for concern in terms of durability.
Yes they do but it’s open by appointment only. There is also a list of retailers that carry Berkeley Ergonomics mattresses in post #12 here.
