Features:.The body is made of one-piece aluminum alloy material, which is sturdy and durable. It has an aluminum alloy base to reduce air leakage, higher precision, smooth use, worry-free and durable, and the texture and appearance are superior. After assembly, the flywheel is not easy to deflect, and the integrated flywheel can not run. Bias phenomenon
.Easy to assemble, even novices know how to assemble, reducing the failure rate and increasing stability
.Instructions for use: The base of the machine is made of aluminum alloy. The base is 10 cm in diameter. The cup (the diameter of the cup is less than or equal to 10 cm, so that Sterling does not fall) is filled with hot water (the water temperature can't be lower than 65 degrees, the machine base) At least 50 degrees to run), the hot water level is close to the mouth of the cup, which will make the Stirling base heat faster. Preheating for about 1 minute, turn the flywheel by hand, the machine can run by itself
.Note: It is forbidden to bake for a short time and it can be operated. Long time, poor temperature control will cause the rubber between the base and the fuselage to leak. It can not be soaked in hot water. It will also cause the rubber to leak out. The heat source cannot be iron cobalt nickel because the magnet in the middle of the sponge piston is magnetic. The material will suck and cause the machine to not turn
.The product is suitable for people over 8 years old. Under 13 years old, it needs to be used under the supervision of adults.

Heaven sent
Size: Jumbo (25-Inch), Color: Dark Grey
My back suddenly decided to show me who's the boss. This reading pillow has been a God send! It is substantial without being too hard, soft enough to be comfortable without being too soft, absolutely no lumps! The outside cover is removable to allow for machine washing and is so soft to the touch. There is a handle on the back that makes it easy to move. This has allowed me to be able to sit upright, much appreciated!

"Plusses" Are Bedrest's Extra High Back & Thick Padding
Bedrest arrives vacuum-packed in a box much smaller than anticipated, but quickly expands to "size", with a longer than usual backside and what appears to be a slightly narrower seating area. " Rest" is very comfortable and thick padding ensures it adequately supports your back. Appearance-wise, the material is somewhat wrinkled/creased (due probably to packaging) and yellow (which is color I got) is a little darker than pictured, with a bit of an orange tint. Carry-handle and arm pockets are appreciated features of convenience. Overall, I'm happy with purchase and look forward to many years of comfortable lounging.
