Felt backed carpets are a superb option for flooring a room on a tight budget. These types of carpet are hugely versatile and can be fitted using traditional gripper and underlay. Felt backed can also be fitted without underlay if desired, rolled directly over the subfloor using a carpet adhesive around the edges instead of gripper. Underlay will always help to add cushion and longevity to the flooring, but felt backed is the option if you don't want to use it. Highly recommended for use in rentals not only for the value, but as it's easy to replace if needed.
