Initial Setting: For newborns, set the mattress support to the highest position to make it easier to reach the infant.
Attachment: Align the mattress frame brackets with the holes on the corner posts. Secure each corner with a bolt and wing nut.
Safety Check: Ensure the "this side up" sticker on the mattress frame is facing correctly. 3. Attach the Front Rail & Footboard

The Bonavita furniture brand (formerly manufactured by LaJobi Industries) underwent significant corporate restructuring and eventual dissolution. As a result, the original manufacturer's website is no longer active, and direct customer support for the "Sheffield" model is largely unavailable. Owners of this crib cannot download instructions directly from a manufacturer URL.
The Bonavita Sheffield typically ships in one large, heavy box. Confirm you have all components:
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.
