Building on a Century of Excellence. From Kit to Kate.

Arnold Lumber 

Seaside Casual was built on the strength and integrity of a 100 year old company, dating back to 1911, when the Arnold Lumber Company was founded by Carold D ‘Kit’ Arnold. Kit and his son Arthur ran the family business (at first a saw mill, and later a retail establishment) with an unwavering work ethic and ingenuity, that was passed along to Arthur “Art” Arnold, Jr., the current owner of Arnold Lumber Company and Seaside Casual Furniture. Art was instrumental in the growth and expansion of Arnold Lumber Company, and it was under his leadership that Seaside Casual introduced their first piece of furniture to the community.


In 1999, Seaside Casual introduced their HDPE all-weather furniture to the market. Known as EnviroWood®, Seaside’s
HDPE lumber is made from recycled plastic, such as milk jugs and permeated with solid pigment throughout. Colourfast and weatherproof, furniture constructed from EnviroWood® can endure corrosive seaside air, a New England winter, or an Arizona heat wave.
The Seaside Casual brand quickly became synonymous with high quality, low maintenance outdoor furniture that looks great, is easy to maintain, and can be left outdoors from one season to the next.

Made in Rhode Island 

With 100 years and 5 generations of dedication, quality, and value built into every piece of Seaside Casual Furniture, Art, Kate and the entire Seaside family of employees are proud to offer “Made in America” furniture that will be enjoyed for years, in harmony with the outdoors.

Made in the USA

We began making furniture at our Rhode Island lumberyard in 1996. It started as a hobby with just one Adirondack chair. With the encouragement of our local community, we began making and selling more chairs. That single design has now grown into a collection of over 50 products.


In 1999 we introduced Envirowood – a 100% High Density Polyethylene (HDPE) lumber. Made from recycled plastic bottles and containers, Envirowood is permeated with UV stabilized pigments that are consistent throughout the entire piece. The result is a smoother and more durable finish that prevents chalking and resists fading of the surface.

Indoor Comfort

Our plastic lumber is milled and routered to simulate the look and feel often found in traditional wood furniture. Joints are secured using mortise and tenon joinery and edges and corners are milled on precise CNC machinery. In short, we produce our outdoor collection at specifications usually applied to interior furniture.

316 Marine Grade Stainless Fasteners

All stainless steel fasteners are not created equal. Low grade stainless or painted components can easily corrode in harsh coastal environments. We use marine grade stainless steel (316) to ensure superior protection when exposed to the elements.

Solid as a Rock

Unlike sheet moulded products, our frames are constructed with HDPE lumber components that are designed to withstand temperature and load changes. Structural aluminum is used to reinforce critical frame members in key locations. The result is a product that will not tip, topple, or turn over on your patio, deck, or lawn.

Slats and Spaces

Appropriately spaced slats are the difference between support and the feeling of "falling through" the seat or back of your chair. We have this perfected so you feel comforted and secure.

It Only Has a Good Side

All of our products are completely finished on all surfaces. This means all backs and seats are slatted and supported so that they look and feel great even when cushions are not in use. Compare our finish to others and you'll see that our way is the best way.

Custom Upholstery

We offer a wide selection of custom fitted cushions made from Sunbrella and Outdura fabrics. These premium fabrics repel water, are stain resistant, and resist fading, even in the brightest of sun so your furniture will look great on day one and day one thousand.

Take it for a Test Drive

We test the ergonomics of our products constantly throughout the design phase and
we believe our customers should have the opportunity to do the same when making a purchase. Because of this belief, we forge relationships with retailers who offer brick and mortar showrooms. These relationships ensure the expertise that we expect and the service our customers appreciate.

Peace of Mind

Our products are backed with a 25 year warranty that offer the support and commitment of a
family-owned company with over 100 years in the making. We stand by our products with confidence so you know you can enjoy their quality for years to come.
