In one sentence, describe what the following article is about: Elevating the head of the bed by six to nine inches (15 to 23 cm) is recommended for both sleep apnea and acid reflux. You should still be comfortable enough to get a full night's sleep, so try starting at a lower elevation instead of going straight to nine inch risers. Basic bed risers cost about half as much as specially designed products. However, they don't have foam that molds to the angle of the feet that results from elevating one end of the bed. If you do go with a basic product, it should still have wells or recesses so the bed feet don't slip over the edge.Avoid lightweight plastic products, as they're not as safe as thick, heavy duty plastic, solid wood, or metal options. Cinder blocks, stacks of wood, or even thick books are your cheapest option. While inexpensive, these options aren't as safe as store-bought bed risers, and many people don't like how they look. In addition, it might be more difficult to ensure you're raising the feet to the same height. Choose the widest blocks possible to reduce the risk of the feet slipping. You can also place non-slip pads, such as those you'd use to keep a rug from moving, under and on top of the blocks to reduce the risk of slipping. One pro is that you can start from a low height and gradually stack more books or blocks until you reach six to nine inches. That way, you can get used to the elevation without having to purchase multiple sets of bed risers.
Summary: Raise your bed at least six inches (15 cm). Use wood, metal, or heavy duty plastic risers with wells. Go with cement or wood blocks for the most affordable option.

In one sentence, describe what the following article is about: These will be the surface of your Quad Steps. You can make these any size you want, but this is an ideal size for training for Ninja Warrior. A standard size sheet of plywood is 4 by 8ft (1.2 by 2.4m). If you cut your squares into 2 by 2ft (0.61 by 0.61m) pieces, you should only need 1 sheet of plywood. The standard size board for framing is 2 by 4 inches (5.1 by 10.2cm) but you can use whatever lumber you have on hand, as long as it is weather-treated and is free of any cracks or soft spots. Place 8 sections of wood in one pile to be used for framing, and the remaining 8 pieces of wood in another pile to be your kickstand boards, which are used to hold the Quad Steps upright as you jump across them. You want the kickstand to rest flush against the platform to hold the platform at an angle. Each cut should start about 1 inch (2.5cm) from the corner of the board. Carefully use a saw to make these cuts. Always use caution when using a saw. Wear safety goggles and keep your hands free from the blades. The framing pieces should be turned up on their sides and should be touching the outside edge of the plywood. Use 4 2in (5.1cm) wood screws for each framing board to ensure they are secure, for a total of 8 on each platform. The kickstands should rest against the framing wood at the corner of the platform. When you have the kickstands aligned with the platform, the whole assembly should stand upright, with the platform propped about 45 degrees off of the ground. Make sure that the kickstands are mounted securely, since they will support most of your weight as you jump. Now, enjoy your Quad Steps! If you want to adjust the angle of your Quad Steps later on, use a bolt when you're attaching the kickstands instead of a screw.
Summary: Cut a sheet of plywood into 4 2 by 2ft (0.61 by 0.61m) squares. Cut 16 2ft (0.61m) sections from lengths of lumber and divide them. Cut off 1 corner of each kickstand board at a 45 degree angle. Lay 2 pieces of framing wood and the plywood on top of each other. Attach the plywood to the framing boards with wood screws. Angle the platform and 2 kickstand boards so they are flush together. Attach each kickstand board to the framing board with a long wood screw.

In one sentence, describe what the following article is about: Since you previously marked the height of the bottom of the header on the king studs, you can now line the header up with those marks and nail it to the king studs. Use at least four 12D nails on each side. Using the marks on the top and bottom wall plates where you previously placed a K for the king studs, attach the plates to the king studs. Again, use 12D nails. Make sure that each connection is flush and perfectly perpendicular as you go. If you are building the frame for the entire wall while framing the doorway, then this is also the point where you will install the rest of the wall studs. Now that the header, king studs, and bottom wall plate are together, you can install the trimmer studs. If you have not yet cut the trimmer studs, double check your measurement by measuring from the bottom of the header board to the top of the bottom wall plate. Using 12D nails, nail the trimmer studs from the bottom of the wall plate as well as to the king studs. When nailing to the king studs, nail from the trimmer stud into the king stud, so that in the event of any protruding nails, they're inside the wall rather than inside the doorframe. Your half cuts in the bottom wall plate should now be flush with the edge of the trimmer studs. Finish cutting away this portion of the bottom wall plate so that the space remains flush with the trimmer studs. Now that you have the rest of the doorway framed, you can attach any last cripple studs if you had a gap between your header and wall top plate.
Summary:
Attach the header to the king studs. Attach the top and bottom wall plates to the king studs. Attach the trimmer studs. Finish removing the half-cut bottom plate piece. Attach any cripple studs.
