Sleepout Curtains offer a generous size of 52" x 76", giving more than enough coverage for your windows and ensuring complete darkness. On the other hand, Sumobaby's dimensions are 50"L x 57"W, slightly smaller and may not provide the same complete blackout effect.

Materials and Care

Sleepout Curtains combine the luxury of cotton flocking with a soft microfiber finish. The addition of Thermaguard™ fabric doesn't just block light; it also provides excellent thermal insulation and sound-blocking properties, enhancing your sleep environment. Sleepout Curtains are also non-toxic and carry OEKO-TEX®, SGS®, and Greenguard® certifications, affirming their safe and high-quality composition.

On the other hand, Sumobaby's curtains are made of High-Density Polyethylene, a synthetic material that may not offer the same comfort and quality as the natural and soft materials used in Sleepout Curtains.

Warranty Details

Sleepout Curtains come with a reassuring 1-year warranty, signaling the brand's confidence in their product's durability and quality. Sumobaby does not specify any warranty details, which could leave customers uncertain about their purchase.
