What to Know About the Sleep Heavy Bamboo Weighted Blanket
A plain guide to the Sleep Heavy bamboo weighted blanket: build, sizes, weights, care and return terms from the store's pages.
The Sleep Heavy bamboo weighted blanket is a bamboo-covered blanket with a bamboo weighted insert, sold in Single, Double and King/Queen sizes and in 6.8 kg and 9 kg weights. Our Sleep Heavy discount code page lists the current code and how to use it.
What the bamboo blanket is made of
The figures below come from the store’s bamboo blanket page. The blanket has two parts: a silky bamboo cover that comes off for washing, and a natural bamboo weighted insert filled with fine-grade glass beads. Precise stitching and rope ties hold the cover and insert together so the weight stays in place, and the store describes a hidden zip system for changing the cover. The store lists OEKO-TEX certification for chemical safety, and says the blankets ship in recyclable boxes.
The color listed is Grey Bamboo.
Sizes and weights
| Size | Dimensions | Weights listed |
|---|---|---|
| Single | 122 cm by 183 cm | 6.8 kg, 9 kg |

| King/Queen | 218 cm by 228 cm | 9 kg |
The store’s guidance on every blanket page is to aim for 10% of your body weight, and it says you can size up or down to preference. Use the store’s size reference images on the product page to compare each blanket against a mattress.
Bamboo or cotton

Sleep Heavy sells its cotton weighted blanket in the same three sizes and weights, so the choice comes down to the fabric. The store’s FAQ says its blankets are designed to be breathable, “especially our bamboo and cotton blankets”, and says cotton and bamboo both help regulate body temperature. That is the brand’s statement, and the page does not say how the two compare with each other.
What the pages do show is the build. The cotton blanket and the bamboo blanket both use a removable cover over a weighted insert, so both are set up for washing the cover on its own. If you want a cover change without buying a whole new blanket, Sleep Heavy also sells spare covers.
Spare covers and bed fit
Sleep Heavy sells spare covers so you can swap a cover while the other is washed. The spare covers page lists grey cotton and mink covers in Single, Double and King/Queen. It does not list a bamboo cover, so if you want a second bamboo cover, ask the store before you plan around one.
For bed fit, compare the three listed dimensions with your own mattress. The store shows size reference images on the product page and says its blankets are shown on standard mattresses. Measure your mattress in centimeters and use that, not a bed size name, because a name such as double can mean different things in different countries.
The bamboo blanket page shows a rating of 4.7 from 22 reviews. Those are the store’s own review figures from its own page.
Two checks before you order: confirm the weight you want is offered in your size, because King/Queen lists only 9 kg, and confirm how many days you have to decide. The store gives you 30 days from delivery to return a blanket under its refund policy, so decide on the weight soon after it arrives.
Care, delivery and returns
The bamboo page says the covers are removable and machine washable, with a gentle cycle and air drying recommended. For the weighted insert it says to hand wash in cold water and air dry.
The page lists shipping of roughly 2 to 5 business days, free shipping and returns anywhere in New Zealand (you pay the return shipping), a 30-day return policy and a 5-year warranty. The listing also describes a 30 night money back guarantee.
One safety point before you buy: the American Academy of Pediatrics advises against weighted blankets for babies. We could not find an age guidance on the Sleep Heavy pages we read, so ask the store about age limits for your child, and talk to your child’s doctor if you have questions.
