Good value on cotton sheets

I was looking for some new sheets and found the Long-staple Cotton Fitted Sheet here. I snagged it during a seasonal sale, got about 20% off which felt like a good deal. It wasn't the absolute cheapest I saw online, but for the quality, it felt worth it. Shipping was free because my order was over $60. The sheet is super soft after a wash and fits my mattress perfectly. Happy with the savings and the product.

Nice silk pillowcase

I got the 22 Momme Mulberry Silk Pillowcase Pair a little while ago. It was a pretty good buy. Shipping took about 5 days to reach my place in Denver, which was fine. The pillowcases feel really nice, super soft. My hair seems less tangled in the mornings too. Overall, happy with the purchase.

Love my new comforter!

Oh my goodness, I just received my Silk Comforter Set for All-Season and I'm absolutely in love! It's so incredibly soft and feels amazing against my skin. I've been sleeping so much better since it arrived. The quality is just fantastic, way better than anything I've had before. The package arrived in perfect condition and pretty fast too. I can't wait to buy more items from here, maybe some matching pillow shams next time. Definitely recommending this store to everyone I know!

Any experience with returns? Ordered a duvet cover and the color isn't quite what I expected. Wondering how much of a hassle it'll be.

R Renee R. 1 month ago
I returned a pillowcase once, it was pretty straightforward. Just fill out a form online and send it back. Got my refund quickly too.

Returns were easy for me too. Just make sure it's still in new condition and you're within their return window. Think it's 30 days or something. No issues at all.

Can I use PayPal to pay for stuff on Seiso or is it just credit cards?

T Tara Hughes 1 month ago
Yup, they take PayPal! I always use it when I order from them, super convenient.

Pretty sure I saw PayPal as an option at checkout. They have all the usual suspects.

Does Seiso actually ship fast? I need some new sheets like, yesterday, for an event next weekend in Phoenix.

D David N. 2 months ago
From what I remember, shipping was pretty quick for my order. Think it got to me in like 4-5 days, and I'm on the west coast.

Depends what you mean by fast. They usually take a few days to process before it even ships. Then standard shipping time on top of that. Might make it, but I wouldn't bet on it for 'next weekend' if you're ordering midweek.

i'm trying to decide between their silk duvet and like, a Parachute one. is the quality really that much better with Seiso or are they pretty comparable?

J Julia Walsh 2 months ago
I've only tried Seiso, but the silk is super soft and feels really luxurious. Haven't had any problems with it after a few washes either.

Honestly, I've had both! Seiso's silk feels a bit more substantial to me, like it's a higher density. Parachute is good, don't get me wrong, but the Seiso one just has that extra 'oomph' of luxury. Plus, I think their pricing is a bit better for what you get.

Hey, does the first-time customer discount still work? Planning a big order and want to save some cash.

R Raj Kaur 2 months ago
Yeah, I just used one last month! Pop your email in the signup box on their site, and they send you a code almost instantly.

I think so. I got a pop-up with a discount code when I first went to their site. Worth checking for that.
