Metal baby cots: size, mattress and buying checks

Compare metal baby cots by verified instructions, mattress fit and practical room dimensions, rather than an outdated price ranking.

Research checked 2026-09-26. We have not carried out hands-on testing of this product.

A metal cot can suit a traditional or contemporary nursery, but the finish tells you little about whether a particular model meets your needs. Start with the exact model, its instructions and mattress specification, then consider appearance.

Compare these details before the price

QuestionWhat to establish
How much room does it need?Confirm the assembled outside dimensions, not just the mattress size. Allow space to reach the cot and operate any moving parts.
Which mattress fits?Use the dimensions and thickness specified for that exact cot. Do not assume a photograph or the phrase “standard cot” identifies the right mattress.
How is the base adjusted?Read the instructions for when each position may be used and when it must be lowered.
What is supplied?Check whether the mattress, fittings and any conversion parts are included. Obtain the full instructions before purchase.
Is a used cot complete?Identify its model and check the manufacturer’s notices and replacement-parts advice. Do not rely on a generic claim that a metal frame is strong.

Keep the sleep space simple

The Lullaby Trust recommends a firm, flat, waterproof mattress that fits the sleep space, with no pillows, bumpers or soft toys. A stated product standard is not evidence that a cot prevents SIDS.

About the earlier five-cot list

The previous page compared Polini Vintage, Happy Beds Vintage, Crowell and Loft listings. We have not established a current, like-for-like set of available offers or model manuals, so they are not presented here as a current ranked shortlist. A current recommendation needs a specific model, verified fit information and a real offer date.

For a buying decision now, request the manufacturer’s product sheet and manual from the retailer. If the dimensions or mattress instructions conflict across listings, resolve that discrepancy before ordering.
