Bad news, I was told about 4 weeks too, about 4 weeks ago. Just called them now and they said approximately 6-8 weeks now (for all the springs).
...on Feb. 5, received this in an email from Unplugged, regarding the "comfort" springs... "...anticipate to be back in stock 4-8 weeks..".
It seems like there is another issue impacting their supply so I would love some feedback from the unplugged team.
Wow. I got my UPP moderate springs 4 days after ordering in July 2020. Sorry to hear of the delays. I’m super happy w the 1” drop.
