Of course, another aspect to a bed is its very size. Double beds (even childrens single beds) are large items. They dominate a small or even medium-sized room. It is imperative too that your bed is stylish and attractive, as well as comfortable. Nobody wants an eyesore in their bedroom, which is a highly private and personal space.
If it is possible for you to try the bedding for some time, it will be better. This way, you will know the comfort level that you will feel with it. Try to ask the seller if you can get a sampler of it so that you can bring it home.
