Softwood is most commonly found in the regions of the world with lower temperatures and is typically less durable, lighter in weight, and more vulnerable to pests and fungal attacks in comparison to hardwoods. They typically have a paler color and a more open grain than hardwoods, which contributes to the tendency of felled softwood to shrink and swell as it dries. Softwoods usually have a lower density, around 25-37lb/cu ft, which can compromise its strength. Density, however, does vary within both softwoods and hardwoods depending on the wood's geographical origin and growth rate. However, the lower density of softwoods also allows it to have a greater strength with lighter weight. In the United States, softwoods are typically cheaper and more readily available and accessible. Most softwoods are suitable for general construction, especially framing, trim, and finish work, and carcassing.
Keep in mind, there are no perfect boards, but try to always use the straighter boards and avoid warping boards. Also, Brandon and I have found that when it comes to picking out lumber at Home Depot and Lowes, they tend to stock up on fresh boards a few days before the weekend starts (so Thursday/Friday). And then, on Sundays and Mondays, the boards are usually really picked over and there isn’t a good selection. Just another tip to keep in mind!
Build your own platform bed frame at your home by following the source linked tutorial given above. The source link also includes more pictures that can help you to build a better bed frame. You can see a step by step set of instructions and guidelines to follow with real life pictures, as well as you can download a PDF file detailing the list of materials and tools you’ll need, know about the length of every board, and most importantly color-coded illustrations of the building process.
There are a few things particleboard is NOT. It’s not medium density fiberboard (MDF)—a material with greater density and weight composed of more uniform particles. It’s NOT oriented strand board (OSB), a material composed of large wood chips and strands that’s structurally equivalent to plywood. It does NOT have great nail or screw holding ability, nor is it all that water resistant; water can quickly cause the material to swell and lose structural integrity. But if you need something flat and cheap for use in a dry place, particleboard will do you proud. Learn how to make a plastic laminate tabletop with a particleboard substrate.
