How Do Sleep Heavy Returns and the 5-Year Warranty Work?

The 30-day return, exchange, 5-year warranty and delivery terms Sleep Heavy publishes, in plain terms.

Updated 14 Sep 2026 3 min read 5 sections

Sleep Heavy offers a 30-day return or exchange on its weighted blankets and a 5-year warranty for manufacturing defects, and both come with conditions you should read first. We keep the current code for Sleep Heavy on its store page.

The 30-day return and exchange

The details here come from the store’s warranty and refund policy page. If you are not satisfied within 30 days, you may return the blanket for any reason and get a full refund, or exchange it for a different blanket. For an exchange you pay any difference in price and the cost of returning the blanket. In every case return shipping is the customer’s responsibility.

Returned blankets must be clean and in as new condition, with no debris or pet fur.
The original receipt showing proof of purchase is required.
The policy is limited to one return or exchange per household.
You must act no later than 30 days after delivery.
To start, email [email protected]. The policy gives a return address in Rangiora and says returns are posted at the owner’s expense unless arranged otherwise.

The store’s FAQ confirms you can return or exchange within 30 days if you chose the wrong weight. If you are unsure between two weights, check the size and weight steps on the product page for the cotton weighted blanket first, then decide.

The 5-year warranty

The warranty covers you only if you are the original purchaser and current owner, and bought directly from Sleep Heavy. It is not transferable. It covers manufacturer defects such as fabric tearing or stitching coming undone.

The policy says it does not cover minor imperfections and slight cosmetic flaws, stains, smoke or water damage, soiled or unsanitary blankets, burns, rips and tears, damage from an insufficient base, abusive use, or personal preferences about texture and comfort. Keep your receipt, because the warranty ties back to the original purchase.

Before you send anything back

A few steps make the process smoother, all taken from the policy wording above.

Find your original receipt or order email. The policy says proof of purchase is required in all cases.
Check the date. The 30 days run from delivery, and the policy says you must act no later than that.
Make sure the blanket is clean and free of debris and pet fur.
Email [email protected] with your order details and say whether you want a refund or an exchange.
Wait for the store’s instructions on where to send it, and post it at your own expense unless the store arranges otherwise.

The refund policy says exchanges are for a different blanket, and that you pay any price difference. If you only want a different weight of the same blanket, say so in your email so the store can tell you how it handles that.

Silk pillowcases and sleep masks

The silk items carry a different rule. Their pages say you can return them within 30 days of purchase and before use, if they are unused and in original condition. Free shipping and returns are listed for New Zealand and Australia, with the buyer paying return shipping. Do not wash or sleep on a silk case if you may still want to send it back.

Delivery times and costs

Blankets are dispatched from the Christchurch warehouse. The shipping page says delivery is free anywhere in New Zealand, including rural areas, with tracking from the time the parcel leaves the store, and that blankets arrive within 2 to 3 business days, with more time for rural deliveries. The product pages say shipping takes roughly 2 to 5 business days, and the FAQ says rural areas may take a day or two longer. Plan around the longer range. The site banner also lists free shipping to Australia.

If a parcel shows as delivered but did not arrive, or the wrong item turns up, contact support at once so the store can look into it.

If you are buying a weighted blanket for a child, note that the American Academy of Pediatrics advises against weighted blankets for babies. Ask Sleep Heavy about its age guidance before you order.
