There is no definitive answer to this question, as what is considered "better" for sleeping can vary from person to person. Some people may prefer to sleep lower to the ground for a variety of reasons, such as to reduce the risk of falling out of bed, to feel closer to the earth, or for the aesthetic appeal of a low-lying bed. We happen to like it because it's in our Italian design DNA.
Sleeping lower to the ground can also have some potential health benefits. For example, sleeping on a low platform bed or futon can help to reduce back and joint pain by promoting proper spinal alignment. This can be especially beneficial for people with chronic pain or mobility issues.
However, sleeping lower to the ground can also have some potential drawbacks. For example, it may be harder to get in and out of bed if the mattress is close to the ground, and it can also make it more difficult to store items underneath the bed.
Ultimately, the decision of whether it is better to sleep lower to the ground or not will depend on individual preferences and needs. If you have chronic pain or mobility issues, sleeping lower to the ground may be beneficial for your health. However, if you prefer a more traditional bed height - like the Modloft Ludlow Bed - a higher bed frame may be a better option for you.
