GROWS WITH YOU– This kit allows you to accommodate your growing child, converting your existing crib to a twin or a full-size bed. This kit converts your full-size cribs to a full-size bed (also known as a double) and your mini-cribs to a twin-size bed (also known as a single) Using your crib’s headboard and footboard, these rails allow you to easily transform your crib into a twin or a full-size bed. This allows for an easy transition for growing children without completely changing their atmosphere.

WHAT YOU’LL NEED– Conversion Kit. Additional Slats. Mattress. 20-30 minutes of installation time. That’s it!! With the purchase of this conversion kit, you will also need to purchase additional slats and a mattress. See our great add-on options below (A box spring can be used in lieu of the additional slats; however, this will cause the bed to be much higher off the ground).

Children grow up quickly. Fortunately, the Babyletto convertible cribs can grow with them. This conversion kit easily converts your Babyletto crib into a big kid’s bed. Using your existing crib headboard and footboard, these bed rails allow you to turn your crib into a full size bed (also known as a double bed). This allows for an easy transition for growing children without completely changing their atmosphere. You will also need a box spring (foundation or bunkie board will work also) and a mattress to convert your crib to a full bed.

Very good service with prompt response when I contacted the service department. Very professional service quality as well. Highly recommend.

Kyung - Amazon Customer

I'm so glad I found this. Our crib had been recalled, so I thought I was never going to find conversion rails for it when it was time to turn it into a full-size bed. The Simmons Conversion kit fit perfect and came with the slats.

Susan - Amazon Customer

Overall an excellent value and I made my grandson very happy!


I absolutely love this bed! It looks exactly like it is pictured. I assembled it myself with no tools needed except for a hammer. It has held four toddlers (age 2, 3 and 3, 4) and one child (9) it did not budge!

Amber - Amazon Customer

They went above and beyond to make sure I had a great experience and I am a very happy customer.


Made a beautiful full size bed.

It actually showed up the next day in perfect condition.

Ronal - Amazon Customer

I got excellent customer service with this seller. I got a response as soon as I asked to return item. I did not measure things before buying it and when i received it the bed was too big for my daughter's bedroom. The item was excellent quality but I could not keep it. I will definitely buying from them again.
