For many, a sofa is a once-in-a-lifetime purchase, or it’s at least a purchase homeowners don’t want to have to make on a frequent basis. In most cases, a sofa’s longevity and quality relate to how it’s made.

Construction tips: Sofas can be made by machine or hand. Depending on its usage, how a sofa is made might be a key factor in how long it lasts. In general, nothing beats all hardwood construction. A sofa constructed of low-grade wood or particle board simply will not last as long as one made from solid hardwood. Also look for sofas in which components such as legs are either made of solid wood or metal.

Another key component is ensuring that springs or coils are well made and the frame is well cushioned and wrapped prior to upholstery. Need a durable fabric? A popular designer choice is commercial- or hospitality-grade fabrics that repel liquids and stains while remaining attractive and aesthetically pleasing.

Type: Sectional or traditional sofa and with arms or armless? While you have a number of choices, allow your room or space to be your guide. In general, sectional sofas work well when you’re looking to frame a space or room using furniture. Sectional sofas work particularly well in corners or where one is looking to frame a wall.

Look for components that fit your desired usage. For example, a chaise would be a better choice than an ottoman if you’re looking to create a sectional component for lounging.

Material: When it comes to fabrics, you have a whole host of options, especially as it relates to fibers. Ask questions and be sure to ask a manufacturer or retailer for cuttings or swatches before making a purchase.

Not crazy about fabric? Leather is still a popular option, especially in areas that might be used by children or a home inhabited by pets. Looking for an alternative to leather? Materials such as artificial leather remain popular.

Foam vs. down: The fill material used to make components such as sofa cushions might greatly affect not only the feel but also the sofa’s overall look. Foam-filled cushions serve as a stiffer option, while down creates a more relaxed look and feel.

Be sure to look, touch, feel and most of all sit on any sofa you are considering before you buy it to ensure that it provides your desired level of comfort.
