Shortly after arriving on Deep Space 9, Benjamin and Jake Sisko went to their quarters and found there were no beds. Chief Miles O'Brien told the two that a spare bunk was available from the Enterprise-D. (DS9: "Emissary")
The Teenaxi had beds. In 2263 of the alternate reality, the leader of the Teenaxi Delegation claimed to James T. Kirk that the Fibonans wanted to see the Teenaxi murdered in their own beds. (Star Trek Beyond)
Cardassian beds were also found to be uncomfortable to Humans, but according to Vash, sleeping in any bed, even a Cardassian one was a luxury to her, since she usually slept on the ground in tents. (DS9: "Past Tense, Part I", "Q-Less")
As Odo was a shapeshifter he did not use a bed, though he had liked sleeping in one when experiencing humanoid life. While sleeping, he would lose his solid state and turn to a gelatinous substance, causing him to slide onto the floor. (DS9: "In Purgatory's Shadow")
Beds were mostly used for getting rest, either by lying quietly or sleep.

That same year, when Guinan and Ro Laren were reverted to a childhood state due to a transporter accident, Guinan described Ro as someone who had jumped on beds as a child, and managed to coax her into doing so, despite Ro's protests that there had been nothing she enjoyed about childhood. (TNG: "Rascals")
In 2373, while attempting to woo Captain Kathryn Janeway, Q placed a romantic bed in her quarters, complete with satin bed sheets. Janeway, however, was not amused and ordered him to remove it. (VOY: "The Q and the Grey")
That same year, when Quark hosted an auction on Deep Space 9, he suggested that his nephew Nog might make a bid on something using the latinum he had stashed under his bed. Nog shushed him and he disappointedly asked if Nog really kept it under his bed. "No, of course not," countered Nog. (DS9: "In the Cards")
