Thanks for your review and for your important feedback! Sorry to hear that the sofa isn't as fresh as you would want it to be- that definitely sounds very disappointing. It sounds like you tried quite a few things as well! Sorry for any inconvenience.
This is certainly not typical feedback that we hear but, since we deal so much in textiles/fabrics, we have heard many accounts of environmental elements causing odors. Since our fabrics are by and large all polyester based, they are usually very cleanable and resilient! There are some blemishes and stains, of course, that are harder to address, specifically when it comes to pets. Still, the Pumpkin fabric is very popular nationwide amongst various manufacturers and retailers and we haven't heard any major negative feedback of this kind before. So sorry again!
I don't think we have any specific remedies in mind outside of the spot cleaning and professional cleaning you have attempted but it bears mentioning that, while these fabrics are "dry clean only" they can be steam cleaned with caution by professional cleaners. It's likely that this is what was attempted. Best of luck and if you think of any way in which we can assist further, please don't hesitate to reach out to us at email@example.com!
