Build your own patio furniture. While this sounds like a great idea, be mindful of the costs involved and also the longevity of the product.[...]Total cost: [...]- assuming you make no mistakes; and that the cost of the 2x4's are in this range. The problem I have with this is two-fold:1. 2x4 studs are not weatherproof. In time they will warp and crack and turn color. I would not consider pressure treated for obvious reasons and anything beyond that (Cedar, redwood or even the composite-plastic boards are phenomenally expensive). At that point, the price of this project will rival your aluminum patio tables.2. Maintenance - you will have to stain/weatherproof each year. These are added costs in maintaining the item.SUMMARY:Nice idea in theory. I love building things, however, save your money and INVEST a bit extra in an all aluminum patio table that will last a long time and not need continual maintenance.
