I would spend 3k and even 4k on a great bed that is something like this.
I'm not sure about this though, firstly I would have to lie down on it to see how comfortable is, I wanna know more about the bottom of the bed is there a pillar at the middle, what type of mattress that is, and how the massage feels etc...
I'm thinking this is maybe overpriced a bit, but I could be proven wrong if I were to try it out.
I would much rather spend 3k on a bed, something that will give me daily happiness, than 3k on clothes and jewelry.
This is not materialism, this is practical.
Save the money you would throw at materialism and save up for this instead.
