Storage bed with LED lights
You can find storage beds with LED lights online or in a brick-and-mortar store. They might be a bit harder to find than the usual bed someone would be trying to buy. Moreover, even if you cannot find storage beds with LED lights it is possible to buy LED lights separately and have the lights installed in the storage bed by using some double-sided tape. On the offhand, you can buy a storage bed with LED lights, but it would cost a lot more than if you installed and bought the LED lights yourself. But the upside to buying a storage unit with LED lights would come with premium features such as the LED lights turning on automatically when the storage unit opens and when it is closed it turns off to make sure that the LED lights burn out and you do not have to use a separate remote to turn on and off the lights.
Double bed with LED lights and speakers:
It is possible to purchase a double bed with LED lights and speakers, it is just that it will probably cost a lot of money when being compared to your standard double bed. This is because everything needs to be easily accessible to turn on from your bed or these features are not convenient. For example, the speakers that come attached to the double bed should have Bluetooth connectivity or you are stuck using a wire to play music or the sound from your device that needs to be connected so may have a cable running across your bed if you want to watch or listen to something using the speakers in your double bed. Moreover, it may be convenient to have a smart tv connected to the double bed instead. At least that way you have less to worry about if you're worried about adding one later to your double bed.
