I didn’t approach my linen with the BIFL. I bought the old ikea linen set sheets about 6 years ago to see if I liked it and it’s still going strong now. I wash gentle with Woolite and air dry.

I got my linen comforter from quince and have had it about 8 months, so I can’t vouch for durability. But they have a 1 year return policy.

The down duvet insert is fjallarnika.

Have you tried linen? I’m similar and I found that after much trial and error I found that for me linen sheets and a linen quilt work well. I add a down comforter on top in the winter but the linen layers seem to keep me cool.

I also read somewhere while on this quest that a lower quality down comforter with a higher percentage of feathers can give you more heft and “cuddle” without the excessive warmth. I’m currently using an ikea comforter that is 90% feather and it’s working nicely.
