Should Nook crib mattresses always be used with a Fitted Crib Sheet?

It's your choice to use a fitted crib sheet or not. Although Nook's crib mattresses do not require fitted sheets, the use of standard fitted sheets might prolong the life of your Pebble Wrap.

What are the major differences between Nook's three crib mattresses?

The Pure is an organic and natural mattress made of coconut coir and natural latex. The Lite and Air mattresses are both non-toxic with safe Certipur foam cores; the Air is ultra-lightweight at only 7 lbs. Price points vary with materials.

Do the Pebble Twin and Full Mattresses need a box spring?

A box spring is not needed as long as the mattress is on a flat surface. We recommend the use of a platform bed with the Pebble Twin and Full mattresses.

Are Nook crib mattresses available in sizes other than "US standard" size?

Our crib mattresses are designed to fit snugly in any standard US crib. Nook’s crib mattresses are built to the larger variance of U.S. standard cribs to provide a nice snug fit. To ensure the longevity of your Nook mattress, we recommend using a crib with a platform, wood slat or solid base. We do not recommend the use of spring-based cribs. We don't stock other sizes, but we can and do make custom sizes, too, so please contact us at info@nooksleep.com to tell us what size you want. We'll give you a price quote and estimated delivery date.

Do I need a mattress pad with Pebble Mattresses?

No. Your Pebble Wraps serve as mattress pads, only better ones than you can buy elsewhere. The Wraps' design and patented fabric technology prevents liquids, dirt and other "messes" from seeping through the surface fabrics, eliminating the need for mattress pads. Learn more about Nook's convenience solutions.

Can I use non-Nook sheets with Nook Mattresses?

Yes. Non-Nook sheets will fit Nook Mattresses. However, Nook recommends the use of Nook fitted crib sheets to maximize breathability in the crib. All Nook products are designed to work in concert with one another to create best-in-class breathability, non-toxicity and convenience. Non-Nook sheets could compromise these benefits.

Can I use a Nook Pebble Wrap on a non-Nook mattress?

The Pebble wraps are specifically cut and sewn for the various Nook mattresses and are not designed to be used on any other mattress. The Nook Pebble wraps and cores of the mattresses are a part of a sleep system designed for breathability, air-flow and comfort.

Do Nook mattresses come in other sizes besides crib, twin, and full?

Nook Sleep Systems specializes in infant and child products. However, we do offer custom sizes. Please contact us at info@nooksleep.com for a quote.

How do I protect the crib mattress core during potty training?

Potty training brings larger messes than the Nook Pebble Wraps are designed to handle. When it comes to the potty training, how to handle your child's specific needs would be a decision for the parents; adding a pad, keeping them in Pull Ups, waking them up to use the bathroom, etc. Nook recommends the Stinky Pad by Essentia for what we hope is a short transition out of diapers.

What belongs in the crib when my baby is sleeping?

Short answer: Nothing. According to the guidelines for infant safe sleep as established in 2011 by the American Academy of Pediatrics, a baby is to sleep on their back, on a firm mattress, alone in a crib that is devoid of bumpers, blankets, stuffed toys, etc. Additionally, Nook recommends that parents and caregivers routinely examine the crib for any other extraneous or loose items that could present a safety hazard.

Should infants sleep face down on their Nook crib mattresses?

No. Nook advises parents to follow current medical recommendations; for maximum crib safety, doctors now believe that infants should sleep on their backs.

What is the recommended age or weight range for children sleeping on the Nook's crib mattresses?

Your Nook crib mattress is appropriate for infants and children up to 4 years old or until they reach 50 lbs. Nook's Twin and Full Mattresses are perfect solutions for your child's first "big kid" mattress.

Will Nook products help prevent SIDS?

The causes of SIDS remain unclear and are still being researched. Experts believe SIDS may be related to low-level toxins found in some nurseries, but there is no definitive research to support this. In 2008, a medical research study from UC-Berkeley and Kaiser Permanente indicated that ventilation in a nursery may significantly reduce the occurrence of SIDS. Because SIDS may be related both to overheating and accidental asphyxiation, Nook is committed to maximizing natural airflow and breathability throughout its product line.

My child is allergic to wool/latex. Can he sleep on Nook's Pebble Pure Crib Mattress?

Components of the Pebble Pure Crib Mattress contain certified organic wool or natural latex in layers beneath the sleep surface. While neither of these materials come in direct contact with your child's skin, Nook does not recommend the Pebble Pure mattress for children with extreme allergies to these materials. Nook recommends its Lite or Air crib mattresses instead. Consult your child's pediatrician for more information on your child's allergies.

Are Nook crib mattresses and other products tested for compliance with health and safety guidelines?

No. Nook advises parents to follow current medical recommendations; for maximum crib safety, doctors now believe that infants should sleep on their backs.

Why is breathability so important?

Research shows that a sleep environment rich in oxygen is critical for cognitive and physical development in infants. It also helps them sleep longer and deeper. Nook applies this knowledge in all products by facilitating better airflow in and around the crib and by ensuring smarter temperature regulation at naptime and nighttime.

What is off-gassing and why is it important to prevent this in the nursery?

Synthetic materials can release chemicals into the air through evaporation. For instance, when you remove a standard infant mattress from plastic, you might smell a harsh odor. That's off-gassing, and it can be toxic to infants. Nook uses only non-toxic materials to ensure that nursery air is cleaner and safer for infants.

Will the Pebble ChangePad fit in all changing trays?

We specifically designed the Pebble ChangePad to fit the most popular size (33”). However, we use a soft foam core so the pad can be compressed to fit snugly into smaller changing trays.

How do I keep my Pebble ChangePad clean?

Machine wash the Pebble cover cold with mild detergent, then tumble dry; do not use fabric softener or chlorine bleach. To clean the core, wipe waterproof fabric with soap and water; DO NOT put the core in the washing machine.

Can I get Wraps in other colors, too?

Yes, you can buy Wraps in as many different colors as we stock, or you can contact us at info@nooksleep.com to see if we can provide a custom Wrap in one of our other colors.

Can I really just wipe liquids from the surface of the Pebble Wrap?

Yes. Nook's fabric technologies create liquid- and microbe-resistant surfaces on all Pebble Wraps, allowing most small messes to be wiped up for a quick and easy clean.

What materials are inside the LilyPad?

The LilyPad consists of 1” of PETE (a woven meshwork of BPA-free recycled water bottles) covered in the organic Pebble material.

How do I wash my Niche Feeding Pillow?

Remove the Pebble Wrap, machine wash it using a mild detergent in cold water on a gentle cycle and then tumble dry. Do not use fabric softener or chlorine bleach. To clean the core, wipe waterproof fabric with soap and water, DO NOT put core in the washing machine.

How do I use my Niche?

It's an all organic feeding pillow designed to support baby while breast or bottle feeding. It is broad and firm to support babies and infants of all sizes as they are feed in the arms of their parents. It also helps prop baby up when learning to sit up on their own. It also makes a great side-sleeper or laptop prop for the rest of the family.

How do I wash my Pebble Twin or Full wrap?

How do I care for Nook products?

All Pebble Wraps are machine washable. We recommend gentle cycle with other soft fabrics only, cold water wash with mild detergent, and tumble dry. Do not use fabric softener or chlorine bleach, which can offset the effectiveness of our nano-coating. Additionally, Nook's fabric technologies create liquid- and microbe-resistant surfaces on all Pebble Wraps, allowing most small messes to be wiped up for a quick and easy clean.

Is my Pebble Wrap water-proof?

Nook Pebble Wraps feature a proprietary fabric made from nano-treated organic cotton and eucalyptus. Wraps are water-resistant, not water-proof as waterproofing would require a plastic backing or chemical agent which are not good for your baby. The Nanosphere fabric technologies used in Nook's Pebble Wraps allow small messes to bead up on top of the wraps for 90 minutes or more for easy clean-up of spills, leaks, spit up. Eventually the liquid may seep into the top layer of the wrap but keeping the core of the mattress dry and protected. The wrap is removable and machine washable.

How do I care for my Nook LilyPad?

What are the benefits of creating a healthy & non-toxic crib environment?

A healthy crib environment eliminates chemical by-products, like off-gasses, that can pollute nursery air. You want your infant to breathe only the healthiest, cleanest air.

Are all Nook materials organic?

No. Nook carefully considers the performance, health, safety and price benefits of organic materials versus non-organic materials. Organic isn't always the best choice for each component or for your budget. But Nook ensures that any material that touches your baby is all-natural. Nook's entire product line, from material selection through manufacturing and packaging, is entirely non-toxic.

Are Nook products hypoallergenic?

Yes. Nook champions materials that cause fewer allergic reactions in infants, featuring all-natural certified organic cotton and wool, eucalyptus, and zinc.

Are natural fire retardants as effective as chemical ones?

Yes. Natural fire retardants are tested against the same federal mandates as chemical ones to ensure they are just as safe and reliable.

Why the pebble pattern?

The asymmetrical pebble pattern increases air circulation over, around and through the mattress cover. Air travels through the valleys between the Pebbles making a more breathable sleep space for infants. And because no two pebbles are the same, every infant can find a unique and comfortable nook.

Do Nook Fitted Crib Sheets negate the benefits of Nook crib mattresses?

No. Nook Fitted Crib Sheets work in conjunction with the each of Nook's crib mattress designs to sustain all the sleep system benefits of the mattresses such as increased breathability, airflow and sleep comfort. Air travels through our sheets, over the pebbles beneath and back up to the infant.
