I thought I would offer an update on my own positive experience with a winter purchase of a Laam seat. I completed the online order form on their website on October 27 and received a pleasant email reply a few hours later from Kaarin at Laam. We arranged for me to get the seat to them which they received on Nov 12. Seth called me on Dec 2 to discuss my needs and selections. He said he was going to have the seat completed and packaged for shipping by the end of the day, which he did. So the seat was in his facility for right at 3 weeks. When adding in the transit time on both ends, I was without the seat for 4.5 weeks total.
I had mentally prepared myself for the possibility of a long lead time and communication challenges even though the riding season is over so my actual experiences were quite reasonable in my mind. In all honesty, I have a spare stock seat and it's winter here in Minnesota so I really didn't care how long the process took.
As for the seat itself, I received it from UPS two days ago and took advantage of dry roads yesterday to give it a quick shake down. After 100 miles at 36F I was ready to get my feet warmed back up but the bum was comfortably cradled in new vinyl and foam. At that distance on the stock seat my sit bones would be howling in protest but I had no such complaint yesterday. A 100 mile ride is far from an adequate test for me however - I will reserve final judgement on the comfort once I can get a ride of several hundred miles in the seat. Initial impressions are good though!
One last note: the quality is excellent.
