In short, it depends on your individual needs and preferences. A bed with storage can be a great added bonus in a bedroom, if you're short on space or if you prefer a streamlined, organized look. The main benefit of getting a bed with storage is that it can provide extra storage space for items like blankets, pillows, toys, books, extra linens, etc. If you don't have the room for a dresser or bedroom chest, having a bed with storage is definitely a viable option.
In addition, beds with storage can make your bedroom look much more organized and spacious. A bed with storage can also eliminate the need for bulky pieces of furniture, saving you more space in your bedroom. Depending on the type you get, it also might be a bit more aesthetically pleasing than a traditional bed.
At the end of the day, it really is up to you to decide if you think a bed with storage is worth it. If you need extra storage, like to keep your bedroom looking neat and organized, or just don't have room for a dresser, getting a bed with storage might be the perfect way to meet your needs.
