How the Mid-Century Convertible Cot arrives
The base heights are the important setting: the higher one for a newborn, so you can lift them without bending into the cot, and the lower one once your baby can sit or pull up.
When it is time for a toddler bed, the conversion kit replaces the front of the cot with a short guardrail. That is a second job, often a year or more later, and the frame should be re-tightened at the same time.
What the pro does on the Mid-Century Convertible Cot
- Cot built square with every bolt fully tightened
- Mattress base set at the height you ask for
- Sides checked for movement once standing
- Later: conversion kit fitted and the frame re-tightened
Before you book: what to send
- Cot or conversion kit, or both
- A photo of the nursery
- Any changing table or dresser to build too
How West Elm assembly is priced
A vetted pro prices your piece from the product link and a photo of the room, and the JACK app shows you that fixed price before you book.
The design moves the price far more than the size. A side table with screw-in legs is a short job. A solid-wood bed with a slatted base, a six-drawer dresser with runners to align, or a sectional sofa whose pieces clip together is a much longer one. Send the product link or a screenshot of the order so the price is for the piece you bought.
Several pieces from one delivery, such as a bed, two nightstands and a dresser, go on one booking for one price. Pieces from other shops can go on the same visit. Where parking has to be paid for, it is added at cost and agreed before you book.
Prefer to pay for the pro's time? Hourly hire works too: as a guide, furniture assembly is typically £35–£75 per hour. For a big delivery, a full-day handyman booking often suits: a flat £350–£400 for up to 8 hours on site.
How it works
Step 1
Share the piece and the room
Paste the West Elm product link or a screenshot of your order (not delivered yet? the link is enough to price from) and add a photo of the room. Mention stairs, a lift or a tight turn on the landing.
Step 2
See the price, pick a slot
A vetted pro prices the build from what you sent. Book once you are happy with the price, choosing a slot after your delivery date; evenings and weekends are available when pros have them.
Step 3
Built, checked, handed over
Parts are counted first, the piece is built and levelled, drawers and doors adjusted, tall pieces anchored and the packaging flattened for recycling. You follow it all in the JACK app.
Frequently asked questions
Can you lower the base of a West Elm Mid-Century cot that is already built?
Yes. The pro moves the base to the lower position and re-tightens the frame.
How much does it cost to have a West Elm Mid-Century Convertible Cot assembled in London?
It is a fixed price for your Mid-Century Convertible Cot, worked out by a vetted pro from the product link and a photo of the room, and shown in the JACK app before you book. If you would rather pay for time, hourly hire is typically £35–£75 per hour as a guide, and a full day is a flat £350–£400 for up to 8 hours on site.
