Quick verdict: Lark is discontinued
Nest Bedding identifies the Lark as a discontinued children’s mattress. If you own one, keep your purchase and warranty records; if you are shopping now, compare the current Puffin Kids Bed with other children’s mattresses. Puffin is an all-foam model, not an identical replacement for the Lark’s older latex-based design.
This article is an editorial look at a legacy model; it does not claim a standardized hands-on test. Availability, terms and specifications should be confirmed with the seller.

What happened to the Lark?
Nest Bedding’s mattress history describes the Lark as discontinued and identifies Puffin as its current children’s mattress. It also says the older BKB Natural became the Lark. Historical model names and materials can be confusing, so check the label and purchase documentation for the exact mattress you own.
Who may find this page useful: owners researching an older Lark, and parents comparing its former natural-material design with today’s choices. For a new bed, start with current options rather than relying on old Lark prices or inventory.
Lark vs. today’s Puffin Kids Bed
The Lark was a latex-based children’s mattress discussed in our original article. The Puffin is a different, 7-inch all-foam design. Nest lists twin, twin XL and full sizes and a maximum weight capacity of 110 pounds for Puffin. Confirm the current listing before ordering.
Choose based on the material and feel your child needs, not the assumption that Puffin is a renamed Lark. See our Puffin guide for more context. If natural latex is a priority, compare a current latex mattress that is appropriate for the child and bed frame.
What was the Lark made of?
Our earlier article described a cotton and wool cover, a latex support layer, quilting foam and a silica-based fire barrier. The original descriptions disagreed on latex layer thickness, so we cannot confidently establish a single layer-by-layer specification for every Lark version. Consult the law tag, original order documentation or Nest Bedding for the exact model.
Certifications apply to the specific certified material or product and its current certificate; they do not establish that every component of an older mattress was organic. Avoid relying on a historical description as a guarantee of current materials or performance.
Returns and warranty: check your purchase
The earlier article gave conflicting trial, warranty and price figures. Nest Bedding’s current policy says children’s mattresses, including Lark and Puffin, are excluded from its 365-night trial and must be returned within 30 nights of receipt, subject to conditions. Do not assume an old listing’s terms apply to your purchase.
For an existing Lark, contact Nest Bedding with the order date, seller, law tag and proof of purchase to confirm applicable warranty coverage. For any new mattress, check the retailer’s return deadline, fees, support requirements and warranty before purchase; a warranty is not the same as a comfort return.

Frequently asked questions
Is the Lark still sold by Nest Bedding?
Nest Bedding identifies Lark as discontinued in its mattress history. Check directly with the seller if you encounter remaining or resale stock.
Is Puffin the same as Lark?
No. Puffin is Nest Bedding’s current all-foam children’s mattress; it does not duplicate the older Lark’s latex-based construction.
Does the 365-night trial apply to children’s mattresses?
Nest Bedding’s current policy excludes Lark and Puffin from that trial and specifies a shorter return window. Verify conditions and the exact deadline with the retailer.
Will a kids mattress fit a bunk bed?
Check the bed manufacturer’s maximum mattress thickness, required support and guardrail clearance before buying. The listed height alone does not establish compatibility.
