This has become quite a thing over on reddit. Purple responds to the video.

Skimming through things there, things start becoming fishy. He's a social media specialist, and certainly mis-represents the lawsuit in his videos, and given he had a ghostbed email address at one point, seems to indicate a rather comfortable relationship with GB (who carefully worded the point on the email issue, leaving it open to admit that the guy did have an email with them, just doesn't presently).

At the same time, I think there is some valid concern over the powder, which I'd guess is to help release it from the mold and aid in keeping it from sticking while rolled. It'll be interesting to see some more independent lab reports than the ones we've seen so far. Also, how much of said powder actually gets out if you, like most people, don't rip off the sock and cover (aside to occasionally wash the cover)? I understand micro-beads can be unsafe to inhale, but in typical use, how much gets from the bed into the air compared to other items used on a daily basis gets in the air?

Also, not sure the Streisand Effect is going on, as Purple was really well known before. Almost every mattress commercial I've seen on the Internet has been for Purple. So I don't think this is spreading their brand... unless this about spreading his brand, in which case it could be.

Okay, so I started going on about the Streisand Effect and jumped subjects to some comments in the Reddit thread about people who've never heard of Purple, then back to the effect. I'll blame that on the fact I was running late for work.

Anyhow, as to said effect, given that Purple isn't suing because he asked about the safety issues, but is instead being sued for not disclosing his relationship with a competitor, I don't know if it applies. Now it probably is bringing far more attention to the plastic beads than otherwise would be there. Now he however is being exposed for his relationships with GhostBed, and lots of questions are being raised about him, which is why I said it might apply to him.

Meanwhile, as I noted in the original paragraph, some people are saying they never heard of Purple, so I was doubting this spreads the brand, nor improves GhostBed's standing.

I had more, but I can't recall all I was going to say as the comment system crashed beyond the point I could come back and edit.

The Streisand effect is when someone attempts to hide something by suppressing it, and that this something instead becomes popularised because of the suppression attempt.

Barbara Streisand was incredibly famous before her particular namesake incident (just like Purple might be).

While suing someone for asking questions is clearly bullshit, his test at the end is pretty disingenuous.

You don't sleep on the actual plastic. There would normally be at least 3 layers (firesock, cover, sheet). Repeat the t-shirt test as you would sleep on it.

The little microbeads effectively prevent large surface areas of their purple material from fully flattening and sticking to adjacent purple material surfaces. So its a lubricant to keep their bed from sticking to itself. That's my assumption at least.

Probably safe enough unless someone was purposefully sleeping on the disassembled mattress and inhaling a lot of the plastic, in which case they could have some lung irritation.

Their R&D and Marketing teams should be working late nights putting together demos of exactly how much of this plastic micro-bead powder makes it up through their covering. I'm thinking demos of people in pristine black clothes jumping on the bed then laying on it, then getting up to demonstrate no dust on them through the mattress pad. They also should be looking at comping people better mattress pads if they still have concerns. Just my read of the situation.

Yeah, I know, I jumped subjects in the middle of the sentience and then back to it. I had a few things I was going to say, and jumbled them together, and failed to edit or proofread. I'll blame it on the fact I was running late for work. Anyhow, fixed the original now.

Read this rebuttle on a public forum on an ad from Purple when someone brought this up:

Purple:
Hi Caitlin, we didn't sue because we has questions, as he asserted. We filed action against Honest Mattress Reviews (HMR), Ryan Monahan & GhostBed for violating the law by spreading false and misleading statements online, including specific statements that GhostBed — a primary competitor of Purple — had previously agreed to remove from its website and various social media platforms. Now, however, those and other false and misleading statements are being made on HMR and Momahan's newly-created mattress-industry-related blog. We have reason to believe Monahan & GhostBed are "in bed together" — some of the connections we've found are here: https://onpurple.com/blog/connections-ryan-monahan-ghostbed.

HMR’s, Monahan’s and GhostBed’s campaign against Purple includes numerous false and misleading statements about Purple and its products and services, including false claims about the safety of Purple’s mattresses, the assumed lack of adequate safety testing for Purple’s products, and Purple’s alleged deception of its customers regarding safety. In fact, many of the statements go so far as to imply that Purple’s mattresses are dangerous and can lead to serious diseases. These statements have been proven to be false and unfounded, and yet, they continue to dishonestly proclaim that Purple's products are unsafe.

The suit is public record and why we sued is clearly spelled out in it, but to clear up what seems to be insinuated — we didn’t sue because he gave us a bad review or because of his 4 safety questions (as he’s asserted). On the contrary, we encourage third-party reviews as an important part of the consumer research process. We are merely protecting our company and intellectual property against a dishonest ”reviewer” with connections to a competitor.

Since every time we discuss the lawsuit publicly evidence of the connection seems to disappear, this is all we can say at this time. Again, the suit is public record and you're welcome to review it yourself.

Apparently Monahan is the "Chief Brand Officer" at Ghostbead - a major competitor of Purple.
