When it comes to choosing between wood or plastic material, there's no right or wrong answer. Wood and plastic have their advantages and disadvantages, and you may want to consider other features before making up your mind.
For instance, molded wood is more reliable than ordinary plastic but less durable compared to frozen polypropylene. Similarly, plastic offers more color options than ordinary wood and molded wood.
If you are on a tight budget and your buying decision depends more on the price tag, then a medium-strength plastic would be great. However, you don't want to sacrifice essential features such as bumpers and quick-release hinges since they determine the functionality, safety, and ease of using the toilet seat.
