The one thing that I can recommend to keep your sheets for a long time is to mend them! I know, I know, I would love to have an affordable, great quality brand that I could recommend to you, that would last for decades, but I haven't found that yet (and am not sure one exists). So the best thing I can suggest is to buy sheets based on fiber content/ how they fit your mattress, and then keep an eye on them! When a hole starts to form, that is when you should take care of it. You can follow this tutorial for small mends, or this one for larger holes. This may not be the answer you're looking for, but if you want to BFL then you have to take care of your things. Also quick rundown of fibers: Cotton: The GOAT, the usual, the one everyone knows. Cotton is pretty breathable, and comes in many forms; Percale (crisp-feeling, cool, classic), Flannel (fuzzy, warm, soft), Sateen (silky, smooth), Jersey (T-shirt material, soft, stretchy, Beware! often mixed with synthetic/polyester!) Linen: The most breathable one out there, if you sleep hot, I recommend this fiber! It doesn’t come in as many forms as cotton, but once you've washed it a couple of times, it manages to combine the soft hug of Jersey sheets with the light cool feel many people want. I have linen sheets, and when I first got them, my boyfriend didn’t like them (said they felt "scratchy") two washes in, and he loved them! Highly recommend. Bamboo/Tencel/Poly etc: Don't bother Hope this helps! More on reddit.com

It would be helpful to know what pricerange you're looking in as well as what type of fabric you want. I do mix-and-match in the sense that my duvet cover is linen canvas, my sheets are Egyptian Cotton sateen and my duvet insert is silk.

Depending on what you want or what you want your bedding to do for you it depends. There's really no such thing as bedding that will have all three factors most look for: longevity, softness and breathability unless you're willing to pay an arm and a leg for it, usually. Most realistic options will have (at most) two of those three, but you have to end up sacrificing one factor in the end.

This is why quality bedding is hard to find and is more often times than not really expensive to own. Even buying from overseas markets is not as cheap as you would expect for really nice quality stuff. A good example is an etsy seller from Lithuania that does really high gsm linen bedding (which is rare to find at such a high gsm) for around $400+ to start with for a Queen size duvet cover.

Let me know your ultimate pricerange and what type of bedding you're looking for (as well as what you want most from it in terms of the three factors I mentioned previously) and I'll see what I can do for you :)

I've been using these from Target for several years - at least 10 years. They hold up really well and feel really nice. They are the only sheets I buy now. I have 2 sets + extra pillowcases and rotate them each wash. More on reddit.com

You’re probably going to laugh, but the old school percale from the 60s and 70s is still in daily use in my house. All 4 kids beds are using sheets from my grandmother, and they’re fine. When I wanted to flesh out sets with extra pillow cases, I used eBay for “new old stock”, Springmaid. I’d say consistent use for decades counts as buy it for life - if you don’t care about funky florals and colors. More on reddit.com
