The depicted is not a regular event or an ongoing promotion.
In 2010, IKEA staged a promotion called In Bed with IKEA at the Olympia concert hall in Paris, in which the seats were replaced with a new bed and mattress line they were promoting. In late 2014, they staged a similar event called Cinema of Love at Kinostar De Lux in Khimki just outside Moscow.
The nearest I found to a real "bed" in a cinema is offered by Blitz Megaplex of Indonesia. They provide "Velvet Class" amenities at several Jakarta locations featuring "lux sofabeds" with "fluffy pillows" and "warm and comfy blanket."
Beyond this, I found few offerings that could genuinely be called a bed. There are numerous theatres which offer sofas or day beds where a couple or small family can share a seat, from The Landmark in Los Angeles to the Portobello Road location of Electric Cinema in London to a number of Bangkok's "VIP cinemas" like SF Cinema City and Paragon Cineplex.
For a further possibility, there are TGV Beanie halls in Malaysia fitted with beanbag couches.
If you expand the criteria further to fully-reclining seats, the venues quickly become too many to list. Even very "Middle America" chains like AMC and Regal are installing leather recliners to try to improve margins amidst declining moviegoing audiences; you can find them even in plain Jane suburbs like Beltsville, Maryland or Dublin, Ohio.
