❓ How soon will I see results with my baby’s sleep?

Many parents notice improvements in just the first few nights — longer stretches of sleep, less startling awake, and easier bedtime routines. Since every baby is different, results may vary, but the calming effect of gentle weight + swaddle-like security is almost always felt quickly.

❓ Is the weighted sleep sack safe for my baby?

Yes — our sleep sack is designed according to pediatric safety standards. The gentle weight is evenly distributed and kept below recommended safety thresholds, so your baby feels calm and secure without any risk. The fabric is breathable, 100% organic cotton, and tested for newborn use.

❓ What size should I choose, and will my baby outgrow it quickly?

Each sleep sack is designed to fit specific age and weight ranges. We provide a clear sizing chart to make sure you pick the right one. The roomy design allows for natural kicking and growth, so your baby won’t outgrow it overnight — most parents get months of use from a single size.

❓ 90 day trial period

We understand every baby is different — that’s why we give you a full 90-day trial period. If you don’t notice better, longer, calmer sleep within three months, you can return the pillow for a full refund.

It’s completely risk-free: try it for 90 nights, love it — or get your money back.

Stop Startles Before They Steal Sleep

Nighttime startles don’t just wake your baby — they disrupt healthy sleep rhythms, leaving little ones cranky and parents drained. When babies lose comfort, everyone loses rest.

The Dream™ Weighted Sleep Sack with NanoCloud™ Fiber gently delivers evenly distributed, soothing weight that calms startles and helps your baby stay asleep longer.

So your family can finally enjoy peaceful nights — and happier mornings. 🌙

Almost Double the Sleep — and Double the Peace of Mind!

Before the Dream™ Weighted Sleep Sack, babies averaged just 3 hrs 45 mins of restless sleep.

After using it, they drifted off for an average of 7 hrs 25 mins of calm, uninterrupted rest — feeling secure, hugged, and comforted all night.

🌙 Technology That Cares — NanoCloud™ Fiber

Every layer is crafted to keep your baby sleeping deeper, cooler, and safer — night after night.
