One of the biggest advantages of guest beds is the luxury they afford when it comes time for guests to stay over. When a guest bed is present, guests aren't necessarily relegated to sleeping on the couch or floor and can rest in true comfort.
Another advantage of guest beds is your selection options. Because the bed will probably not be used on a regular basis, you will not need to purchase the top of the line frame or mattress. You can also choose a type of guest bed that fits into even the smallest of guest rooms. This allows you to double this room as a guest room/office and makes accommodating guests easy.
One more advantage is that the right guest bed can serve a dual purpose. Sofa beds make great guest beds because they can be set up quickly at short notice, or when not in use, enable you to transform the guest room into a den or study. When not in use, the bed will be used as a sofa and won't take up nearly as much space as it does when it is folded out into a bed.
Guest beds are also very handy and can serve a wide variety of purposes. You may choose to purchase a small single bed or day bed in order to save space, but add a trundle for added capability. When not in use, the trundle can be stored underneath the bed and pulled out and popped up when needed. Trundle beds may also be available for larger beds, thus affording you even more space for more than one guest.
Guest beds are easy to purchase. Any furniture store along with various other outlets carry a wide variety of beds of all types, shapes and sizes. You will have no trouble finding a bed that will fit your needs and accommodate any guests. You can also purchase a wide variety of mattresses again, from inexpensive to quite costly. This makes purchasing guest beds easy and allows you to choose the bed and bedding for your specific guest situations. The options are literally endless and you will never be short a comfortable bed. Your guests will also appreciate this because it will enable them to get a good night's sleep in a room that affords them privacy.
