Some of the frames are from Sims 2 and some are from Sims 4. Although most of the Sims 4 frames have been done by other creators. I had to size them all to fit my mattresses.
The mattresses use the Sims 2 bedding format. The long blanket version does require Seasons everything else is the base game.
No Cheats are needed to place the mattress or the frames.
The regular mattress was from the queen bed that has 10s for energy, and stress and I believe it is a discomfort setting. I set the long mattress via the tag and within the coding for the type.
There are 90 bedding textures for each mattress. I believe I have all of the EA textures and many of my own. I also made the pillows larger.
I added some basic recolors for the Sims 4 frames as most of the EA textures are so dark and dreary. I like bright and clean textures myself.
