Thank you for choosing the Bonavita Sheffield Lifestyle Crib. This modern, convertible crib is designed to grow with your child — from a full-size crib to a toddler bed, and later to a daybed. Please read all instructions before beginning assembly.

Step 1 – Prepare the Area
Clear a soft, flat surface (like a carpet or blanket) to avoid scratching the wood.

Step 2 – Attach the Fixed Side to Head/Foot Boards
Lay the headboard face down. Using the provided bolts and barrel nuts, attach one end of the fixed side panel to the headboard. Repeat for the footboard. Tighten firmly but do not over-tighten.

Step 3 – Install the Mattress Support
Choose the mattress height:

Insert the support brackets into the pre-drilled holes at your chosen height. Lower the metal or wood mattress support onto the brackets.

Step 4 – Attach the Second Fixed Side
Secure the remaining side panel to both the headboard and footboard. Ensure all bolts are snug.

Step 5 – Add the Slats
Place wooden slats across the mattress support (if not pre-attached). Slats should fit snugly with no gaps > 2 3/8 inches (6 cm).

Step 6 – Final Tightening
After all parts are connected, go back and fully tighten all bolts with the Allen key. Check for wobble.

The "Lifestyle" designation indicates this crib converts from a standard crib to a toddler bed and potentially a full-size bed. Without the specific paper manual, standard assembly logic for this era of Bonavita cribs applies:

Spread a soft blanket on the floor to protect the crib’s non-toxic finish. Unpack the hardware kit and match each bolt to the diagram in your original manual (or the sticker usually affixed to the inside of the footboard). Sort screws by length.

If you need a PDF of the original manual:

Alternatively, retailers like Amazon, Buy Buy Baby, and Target often host product manuals under the "Product Guides and Documents" section of the listing.
