I requested this as a Christmas gift. I received the full bundle as follows: Fitted sheet, flat sheet, duvet cover, 2 sham pillowcases (which are really standard size pillow cases) and 4 queen sized pillowcases because we made the mistake of adding on an extra set of pillowcases not realizing they already came with the sheet set. It did not occur to me that there were 4 items in the sheet set photo and it's not detailed very well on the product page for the bundle and save. Anyway, no big deal, we just have an extra set. Here are some photos, the first after the first wash and the second after the second wash 10 days later.
Positives: Way more affordable than other brands (maybe at the cost of sustainability though the verdict is out on whether bamboo is actually sustainable - I just really wanted soft sheets). They are extremely soft and not too warm to sleep with (perfect for me who has sensitive skin and sleeps cold and my boyfriend who sleeps hot). The color of the fabric is as pictured online. I have the sheets and pillow cases in the light gray color and the duvet cover and sham pillowcases in the olive green color. It looks and feels nicer than the crappy cotton bedding I've bought from Simon's and Ikea here in Canada (Simon's being particularly overpriced), and nicer than the bamboo pillowcases I've bought from Linen Chest, which were decent, but not quite as soft. Note that Quince does not ship to Canada, I had my parents order this for me in the US since we were visiting for the holidays.
I washed these before first use less than 2 weeks ago. Washed according to the label, cold water, gentle cycle, separate from any other material. I also washed the olive duvet and pillowcases separate from the gray sheet set to avoid any colors bleeding. Before first wash they felt almost satiny and I was skeptical, but they came out like butter.
I wouldn't fault Quince for this as it is likely just bamboo in general, but it is very slippery. The top right corner of the fitted sheet comes off every single night, a problem I've never had with other sheets. Not a deal-breaker, we can just use clips. We had to get a new, larger duvet insert since the duvet is full/queen and our duvet was full size. I love having a bigger duvet now, but the heaviness of the larger blanket it being oversized for our bed, and the slipperiness of bamboo means the blanket is sometimes falling off the end of the bed and can get annoying. Again, not a dealbreaker for me. One thing to note is that when looking for duvet inserts, I found that duvet sizes are wildly inconsistent between Simon's, Linen Chest, and Ikea, but found one that fit the duvet cover (was the same length but bigger by 2 inches on each side, which I don't mind. Maybe comforters/duvets in the US have a standard size that would fit this.
What is very disappointing, however, is the quality, even at this lower price point. I already started noticing faint discoloration on the light gray sheets (some faint whiter areas), particularly toward the top of the sheets where we are laying or sitting up in bed. Noticed this before the first wash. In addition, there are some pulls (presumably from our toenails) on the bottom of the sheet. This is a relatively delicate fabric. After the second wash today, I was really disappointed to see the beginning of some faint pilling on the duvet cover and sheets. We've washed them exactly according to the instructions and have been pretty gentle with the bedding so far. Finally, and this is the most disappointing thing for me, is the dark splotches that have appeared on the olive pillowcases (the ones we've mostly used for sleeping). I assume it was caused by drooling or oils in our hair, but I've never seen a pillowcase get discolored like this, let alone after less than two weeks of use. I'm so upset that it is already aging like this.
All that being said, they are still incredibly comfortable to sleep with, but I would potentially update my review over time if the quality deteriorates more. They feel luxurious and the quality issues I mentioned here aren't particularly visible at this point. I don't think they are a bad purchase persay and as of now would still recommend them if you really want bamboo and have a lower budget, but even with how delicate bamboo can be, I'm a little disappointed after being so excited a few weeks ago (mainly because I have so much trouble deciding to buy things because everything seems to be made like crap in the last couple years and I prefer to invest in nicer quality when I can).
