Most frequently asked questions.
How do I wash my sleepwear?
To wash your sleepwear, please follow the washing instructions on the tags. If you have cut your tags after purchase, then it is recommended to wash with Slumber Cloud Free & Clear Laundry Detergent or a mild detergent in cold water on a delicate spin cycle. When it’s time to dry your sleepwear, please dry on low heat or air dry. Do not iron your sleepwear. To reduce wrinkling, take your sleepwear out of the dryer and immediately place it on your bed or use a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.
Does Free Shipping Apply To International Orders?
Free shipping is only valid for US and Armed Forces delivery addresses. However, we do offer discounted shipping rates to Canada addresses.
Do you ship internationally?
Currently, we only ship internationally to Canada. At the time of purchase we include the cost of shipping, taxes, and duties for Canadian shipments. No additional fees will incur at delivery, but if they do please contact our customer service team at info@slumbercloud.com to take care of the issue. For all other countries, if you find a forwarder or have a friend or family member here in the states, we would be more than happy to work with you to get it there.
Can I still return an item even if it's been washed?
We accept returns in any condition within 60 days of purchase! We want you to absolutely love your new bedding, so if you wash an item, try it out, and decide it's just not for you, we can definitely still initiate a return. Please note we do our very best to donate all returns to local charities instead of a landfill. We appreciate your help in this process by washing any used items before returning them to us.
Are shipping fees covered for returns?
All shipping fees for domestic returns are completely free! When you initiate a return through our returns platform, you will receive a prepaid shipping label to get the item back to us. If you live outside the US and are looking to initiate a return, please check out the return policy in the International FAQs.
