Private Label Mattress Spec Sheet: The Decisions That Protect Your Margin
Most private label mattress projects do not go wrong at the factory. They go wrong a few weeks earlier, when the brief that reaches the factory is a product photo, a target price and the word “medium”. Every detail the factory fills in for you is a decision you did not make, and some of those decisions end up on your returns report.
KaneMan has made mattresses for brands and importers since 2005, beginning with an OEM client from Malta who trusted us with his trademark. The pattern we see is consistent: the buyers who launch smoothly are the ones who arrive with, or build with us, a complete specification. This guide walks through what belongs on it and why each line matters to your margin.
The Real Problem
Why A Photo And A Target Price Are Not A Brief
A photo shows the cover and the height. It does not show foam density, spring count, edge construction or what sits between the springs and the comfort layers. Two mattresses can look identical in a listing and behave very differently after six months. When those details are left open, a factory will usually fill them in to hit your price, and the easiest place to hit a price is inside the mattress, where you cannot see it.
The Specification
The Lines That Belong On Every Private Label Spec Sheet
This is the structure we use when we work through a new line with a buyer. If a line is blank, it deserves a conversation before sampling, not after delivery.
| Spec Line | What To Define | What Happens If It Is Left Open |
|---|---|---|
| Sizes | Exact dimensions for each market, with tolerance | US, UK and EU sizes are not interchangeable. A near-miss size will not fit local bed frames or bedding. |
| Finished Height | Height after unpacking and recovery | A mattress that measures short of its listed height reads as “smaller than advertised”. |
| Support Core | Spring type, count per size, wire gauge, edge support | Spring count and edge construction are easy places to reduce cost unseen. |
| Comfort Layers | Material, thickness and density of each layer, in order | “Memory foam” covers a wide range of densities. Lower density softens and dents sooner. |
| Firmness Target | A target agreed against a physical reference mattress | “Medium” means different things to different markets and different people. |
| Cover Fabric | Fabric type, weight in GSM, colour and quilting pattern | Lighter fabric wears faster, and colour drift between batches looks like a different product. |
| Fire Safety | The standard your market requires and the report covering this exact construction | A report for a different construction may not protect you at the border. |
| Labels | Law labels, care labels, brand labels, country of origin | Missing or incorrect labels can hold a shipment. |
| Packaging | Roll-packed, flat compressed or flat, carton print and inserts | Packaging can change freight cost per unit more than many material choices. |
Comfort
Agree On Feel With A Reference, Not A Word
Firmness is the most common source of disagreement between a brand and its factory, because it is described in words and experienced in the body. Our approach is to agree on a physical reference, either a mattress the buyer already sells or one of our existing constructions, and then record any adjustment in writing. “Slightly firmer than our current Queen” is something a production team can execute. “Medium-firm” is not.
Once a feel is approved, the layer structure that produced it becomes part of the specification. That is what keeps the hundredth unit feeling like the sample.
Cost
Where Cost Can Come Down Without Showing Up In Reviews
Not every saving is a bad saving. Some choices change cost a great deal and comfort very little; others do the opposite. These are the principles we share with buyers:
- Look at packaging first. Moving a range to roll packing can lower freight cost per unit because more mattresses fit in each container. Our guide to choosing between roll-packed and flat-packed shipping covers the trade-offs.
- Keep density where the body touches. The top comfort layer takes the most wear. Lowering its density is the saving most likely to return as complaints about dents and softening.
- Simplify the range before simplifying the mattress. A few well-built models that share components are often easier to produce well than many models built down to a price.
- Spend where the customer can see and feel it. A distinctive cover or a woven label is visible at the point of sale. A hidden layer change is not.
Your Brand
Protecting Your Design And Your Name
When a buyer gives us a trademark, the expectation is simple: the product carries their name and only their name. Before production, agree in writing who owns the custom elements of the line, such as cover artwork, label designs and any construction developed specifically for you, and that these will not be offered to other buyers. A good factory will raise this before you do. If a supplier avoids the subject, treat that as information.
Before Sampling
A Short Checklist Before You Request Samples
- Your target market and the exact sizes it uses
- Retail price point and sales channel: store, online or project
- A reference mattress for comfort
- The fire safety standard for each destination market. See our market-by-market compliance guide.
- Preferred packaging and shipping method
- Label and branding files
- Expected annual volume and launch timing
With these answers in hand, a factory can quote what you actually want instead of what it assumes you want. To understand what each layer contributes before you set your targets, read why mattresses come back and how to read foam density and springs.

Talk To Our TeamFrequently Asked Questions
What should be on a private label mattress spec sheet?
Exact sizes for each market, finished height, the support core, every comfort layer with its material, thickness and density, a firmness target agreed against a reference mattress, cover fabric and weight, the fire safety standard for your market, labels and the packaging method.
Why does my bulk order feel different from the approved sample?
Usually because something that affects feel, such as foam density or the spring unit, was not written into the specification, so it could change between sampling and production without breaking the agreement.
How do I agree on mattress firmness with a factory?
Use a physical reference mattress instead of a word like “medium”, then record the layer structure that produced the approved feel in the specification.
Can I lower private label mattress cost without hurting quality?
Often, yes. Packaging method, a simpler range and shared components can reduce cost with little effect on comfort. Lowering the density of the top comfort layer is the saving most likely to show up in reviews.
