When choosing a patio lounge chair, it is important to consider the materials used to construct the chair, as well as the aesthetics, and the comfort level of the chair. Be sure to test out the chair for several minutes if possible, and be sure to shift your weight while sitting in the patio lounge chair to check for solid construction and comfort. Wood, plastic, and even metal are common choices of materials for a patio lounge chair, and each will have its own advantages and disadvantages, especially in relation to weather resistance.
Wood chairs provide a pleasing aesthetic and solid construction in most cases, but you will need to choose a patio lounge chair constructed from the right type of wood in order for it to be adequately resistant to weather damage. Cedar and teak are the best choices for such purposes, since these woods are naturally beautiful and also naturally resistant to water damage as well as bug infestations. The drawback to such woods is the higher cost: since these woods are so desirable for both their beauty and functionality, you should be prepared to spend a little extra on them. Consider it an investment, however, and realize that choosing the higher quality woods will mean a longer life for the chair.
Comfort and functionality are perhaps the most important considerations when choosing a patio lounge chair. You will undoubtedly avoid sitting in an uncomfortable chair, and what one person may find comfortable may be completely uncomfortable to you. Be sure to try out several chairs made from different materials to find the one that works best for you. Some patio lounge chair models recline, adjust, or otherwise fold up for comfort or storage, so be sure to test out these features as well. Make sure any features are easy to use without requiring help from a partner.
If you are considering a patio lounge chair with upholstery, be sure to choose upholstery that will resist water damage and will not absorb water from rain or other sources. The cushions should be thick enough to be comfortable, and they should be made from synthetic materials that will resist fading in direct sunlight. Synthetic materials will be easier to clean and maintain, and they will usually be resistant to water damage. Be sure the cushions can be removed for storage during the winter, and that they can be secured easily to the chair to prevent shifting during use.
