After years on the search for the best cost:quality bed sheets I think I've completed my study. Tried Sheridan, Ettitude (rubbish), Target and countless others and surprisingly, I've ended up with Kmart as my go to.
These sheets are 100% cotton (don't waste your time with 'cotton blend'). The whole thread count thing is a bit of a sham, especially for a lot of non reputable sellers. The Kmart 400TC here seems like a smoother and better quality sheet than a lot of the '1000TC' sheets I've used. And most importantly they're only 25 bucks. For comparison sake even the king size version of this is only $2 more, at $27 here. Incredible value.
There are a bunch of colours:
If you're not in a Kmart area, free shipping kicks in at $45. In that case I suggest getting either two of the sheets or combining the sheet with two of the same style 400TC 100% cotton pillow slips.
This deal is in the same vein as Dominos Pizza's $5 value range and the beloved $150 Boost yearly deal (RIP), just because they're RRP, doesn't mean it is not a bargain.
Just wanted to share, since my little family find these sheets perfect and they're comparatively so much cheaper and better than others. Hope it helps someone :)
