Overnight the FDA in USA released a statement deeming sleep positioners (sometimes called "nests") a SIDS risk.

The Lullaby Trust in the UK have long since hinted similar, but kept away from outright stating the products are unsafe. Instead reitterating best practice of a firm, flat, mattress clear of anything.
According to the BBC, retailers have already started reacting by removing products from sale:

They mention Tesco, Mothercare and EBay, but I can find baby nests on all but the Tesco website as if 10am this morning. It's either incorrect reporting, a responce in US retailers rather than UK branches of these retailers, or still Work In Progress to remove products.
No brand names are used throughout the initial report or media reports. The question is - is the Sleepyhead a baby positioner or nest? I know it has a massive fan base on Mumsnet. Will the Lullaby Trust follow suit?
