Our advice Buying Guide

Universal crib conversion rails allow for a seamless transition between a crib to a baby bed to toddler bed to a full-sized bed. These protean add-ons give you the much-desired assurance that your baby is neatly tucked in and won’t be able to hop or fall out of bed on their own.

As the child grows, the rails extend to accommodate a bigger sized bed until the child is fully grown. A universal crib conversion rail is an investment that will last for years, if done right.

Makes it all the more important for you to be doubly careful when you select one for your home. Here are some of the factors that will impact your purchase and your experience with these rails.

How to ensure the compatibility of crib conversion rails?

Despite being labeled ‘Universal’, which makes one believe that the rails would automatically be compatible with any standard-sized crib and conversion kit, you’d want to ensure compatibility before you buy it.

How do the rails fit with the crib or the bed? Is the hardware included or does it require additional components or accessories to attach?
Does it have a safety strap mechanism that secures it to the main frame of the bed?
Is it a 4-in-1 option that allows conversion from crib to day bed to toddler bed to full sized bed? Or is it limited to just two or three stage transformations?
Does it provide the required safety for the child at different stages of their growth?

What are universal crib conversion rails made of?

Universal crib conversion rails can be made of solid wood, MDF, plywood, plastic and metal. Metal and solid wood tower above the rest when it comes to durability, stability and aesthetics. Metal works best if you are looking to add a protective mesh screen to the rail.

Oak, maple, cherry wood, cedar and pine are some of the local varieties of wood used for making rails whereas rubber wood is a sustainable variety that is now used globally for making furniture.

These can be finished and stained in hundreds of ways to match the décor and they last for years with minimum upkeep. But they usually cost high upfront and if you aren’t looking to spend that kind of money, then plywood or MDF offers a safe middle ground. It’s not as durable as wood or metal. But it isn’t as flimsy as plastic either.

What's the design of universal crib conversion rails?

Most universal crib conversion rails have the horizontal slat design which is a proven one. It is safe and keeps even the most rambunctious toddler neatly tucked in. Look for one that’s easy to disassemble when not in use. How much storage space will be needed to tuck it away?

How to recognize child-safe crib products?

What looks like a stunning finish in pictures might, in reality, be teeming with VOCs, formaldehyde and other toxic stuff that have no place in your child’s room. Buy child safe products that have no-VOC or are rated for low VOC. Finishes must be water-based and without flame retardants. Glues, if any, should be non-toxic. If the manufacturers don’t mention this anywhere in the product descriptions, reach out to confirm.
