I’ve heard lots of good feedback from here
Calming Moments - Australian-made weighted blankets
They are Australian made, have great variety of colours/textures/patterns, and are very well made. Guaranteed for 2 years. They are happy to have a chat with you if you’re not sure what you need. I recommended them on old EB in a similar thread and the OP purchased one and said it was beautiful looking and it worked.
Not everyone enjoys the sensation. Some people love them straight away, others take time to get used to it, and others just don’t get used to it. Some people prefer to use them when awake (watching tv or reading) but not to sleep with. They do have a decent resale value if they aren’t useful for your circumstances.
Imports are cheaper, but they generally have different fill. IME they are not usually as easy to wash. They also only come in a few different weights. It is recommended that the blanket is 10% of body weight. Having a blanket that is the correct weight makes a difference to how it feels to the user.
And no, I don’t have any financial interest in the company! (There are also a couple of other Australian companies, other than the one I mentioned. I’m sure they are good too - I don’t have experience with them though).
