Dani Reiss also entered the startup's new independent board directors along with Karen Katz (board member of Under Armour and former CEO of Neiman Marcus Group). With the new round of funding, the company was valued at $1.1 billion, according to Bloomberg and Casper Sleep. On January 10, 2020, Casper Sleep Inc filed an S-1 with the U.S. Securities and Exchange Commission declaring their intention to IPO under the ticker CSPR. On February 6, 2020 it went public at $12 per share, translating to a market value of $476 million, listing on NYSE under the ticker CSPR. On March 31, 2020, its stock dropped to $4.12 per share, translating to a market value of $163 million, down from its $1.1 billion valuation in March, 2019. In April 2020, Casper announced the winding down of its European operations and laid off 21% of its staff (78 people) after a poor IPO performance and declining revenues due to the 2019–20 coronavirus pandemic. Additionally, the company announced that Greg Macfarlane, Casper’s CFO and COO, will depart the company in May. Casper mattresses consist of four types of foam, memory foam, and polyurethane support foam. Casper mattresses were previously only sold online but in 2019, they began launching retail locations after piloting successful pop-up shops in large cities like New York and Los Angeles. Each mattress is sold with a 100-day return policy. Returned mattresses have been donated. In November 2015, the company expanded their product offering to include pillows and mattress/bed sheets. In August 2016, Casper introduced their fourth product, a dog mattress. The company launched its second mattress model, The Wave, in August 2017. Casper used a silicone polymer for The Wave that provides improved ergonomic support. A third budget-focused mattress was introduced in October 2017, The Essential. Compared to the original mattress, the essential only has three layers of foam, is thinner, and the cover is non-removable. Casper published "Van Winkle's", a news website focusing on sleep until November 2018. After the shutdown of Van Winkle's, Casper announced a quarterly lifestyle magazine, "Woolly". In April 2018, Casper introduced an adjustable bed frame. In June 2018, the company has added to its (one-pillow) pillow line with a new product: the Nap Pillow.
