How we score mattresses and beds

Methodology v1.3, last updated 14 May 2026. View changelog.

BedBoy is a UK affiliate comparison engine, not a test lab. Nobody here sleeps on a mattress for a fortnight and then writes it up, and you should be suspicious of anyone claiming they’ve done it across 750-odd products. Every product carries a BedBoy Score built from keyword analysis of customer reviews on the retailer’s own listing, construction-type benchmarks, retailer policy data and aggregated star ratings. This page sets out how each input is measured, where the data comes from, and where the model runs out of road.

What the BedBoy Score is

The headline BedBoy Score visible at the top of every product page is the unweighted mean of every scored category for that product, on a five-point scale, rounded to one decimal place. A 4.2 means it averages 4.2 out of 5 across the categories we’re able to score. The per-category breakdown on the same page shows you exactly where those points came from, and what the evidence behind each figure was.

The score is an algorithm applied the same way across hundreds of products, so the comparison stays fair. That’s the whole reason it exists. It’s not the opinion of a single tester and it doesn’t depend on which reviewer happened to leave feedback on a given Tuesday. Every BedBoy Score page includes a per-category evidence panel that shows the signal counts and derivation method behind every figure.

The scoring categories

Categories are matched to the product type, so you won’t see a mattress marked on assembly. Edge support and pressure relief are mattress ideas, assembly and storage are frame ideas, washability belongs to bedding, and nothing is scored against a category that can’t apply to it. A mattress is marked on ten, a bed frame on eight, a headboard, duvet or kids bed on six. Retailer guarantee and customer sentiment are the two that appear on everything.

Bedroom furniture and sofa beds carry those two universal categories and nothing else. Neither one’s got a rubric of its own yet. We’d rather show two honest categories than invent a thin set to fill the gap, however odd the short list looks.

Mattresses

1. Comfort. Derived from keyword signals across the imported review pool. The model counts positive mentions (comfortable, supportive, good night’s sleep, and related phrases) against negative mentions (uncomfortable, too firm, too soft, and related phrases). The net signal as a percentage of the review sample determines the score against a published five-point rubric.
2. Edge support. Where reviewer commentary on edge support is sufficient, the score follows the same keyword-signal method. Where it is sparse, the score falls back to a construction-type benchmark: pocket spring and hybrid builds score higher; open-coil and memory-foam builds score lower. The evidence panel on the product page states which method was used.
3. Motion isolation. Same dual-source method as edge support. Reviewer commentary from couples and combination sleepers drives the score where available; construction type provides the fallback signal where it does not.
4. Heat retention. Same keyword-signal method applied to temperature commentary in the review pool. Positive mentions (cool, breathable, temperature-neutral) versus negative mentions (hot, sweaty, night sweats) drive the score. Memory-foam-dominant products naturally attract more negative heat signals; airflow-engineered hybrids attract fewer. Gel-infused and cool-tech variants receive an uplift in the construction-type fallback.
5. Value. Driven by reviewer commentary on price-against-experience. Positive mentions (worth the money, good value, would buy again) against negative mentions (overpriced, not worth it, poor quality for the price) determine the score. Price data from the retailer listing informs the background context but the reviewer signal is the primary input.
6. Pressure relief. How well the mattress eases the hips, shoulders and lower back. Scored from the same keyword method, and the category that matters most to side sleepers and to anyone with a joint or pain concern.
7. Durability. Whether the mattress holds its shape and feel over time. Sagging, body impressions and surface wear turn up in reviews left months or years after purchase, so this category leans on the older end of the review sample rather than the average of it.
8. Off-gassing and setup. How quickly the mattress is ready to sleep on after unboxing, and how strong the initial smell is. Rolled memory foam scores lowest here; a traditional sprung mattress has no off-gassing to report.

Bed frames

1. Build quality. Sturdy construction; absence of creaks and wobble in real-world use. Keyword signals from owner reviews.
2. Assembly experience. Whether the flat-pack went together easily, clarity of instructions, missing-parts incidents.
3. Storage. For ottoman and divan-base frames: lift mechanism, hydraulic struts, usable storage volume. Marked “not scored” on frames with no storage.
4. Style and finish. Appearance, fabric or upholstery quality, perceived value of the finished frame in the room.
5. Mattress fit. Whether the buyer’s mattress sits cleanly inside the frame without gaps or sliding.
6. Material. Quality and longevity of the frame material itself. Solid wood scores highest, metal and well-made upholstered frames sit in the middle, and thin composite or particleboard frames score lowest.

Headboards

1. Build quality. Sturdy construction; rigid mounting; absence of wobble against the wall.
2. Mounting and fit. Ease of attaching to a divan or fixing to the wall; correctness of supplied fittings; sizing for the bed.
3. Cushioning. Padding depth and comfort for sitting up against the headboard.
4. Style and finish. Appearance, fabric quality, perceived finish of the headboard in the room.

Bedding (duvets, toppers, throws, sets)

1. Warmth. Whether the product delivers on its stated temperature promise: TOG ratings on duvets, season suitability on throws.
2. Filling quality. Loft, plumpness, evenness of fill; resistance to clumping or flattening over time.
3. Washability. Holds shape and colour through machine washing; shrinkage or fading issues.
4. Materials. Fabric softness, breathability, perceived quality of cotton, microfibre, or down.

Kids beds

1. Safety. Absence of pinch points, secure rails, no hazardous gaps or sharp edges.
2. Sturdiness. Whether the frame stands up to jumping, climbing, and the general wear of children using the bed.
3. Age fit. Size and design suited to the age range it was bought for.
4. Style. Appeal to the child; visual fit with their bedroom.

Universal categories (every product type)

6. Retailer guarantee. Derived from the published trial period, manufacturer warranty term, and return policy of the retailer that lists the product. The score is the average of three equally-weighted sub-scores: trial length (5/5 at 100+ nights, 4/5 at 60-99, 3/5 at 30-59, 2/5 at 14-29, 1/5 below 14); warranty term (5/5 at 10+ years, 4/5 at 5-9, 3/5 at 2-4, 2/5 at 1 year, 1/5 below); and return cover (free comfort exchange scores highest, free returns next, paid collection mid-band, no returns lowest). The evidence panel lists the exact policy terms used.
7. Customer sentiment. The raw mean star rating across every active owner review for the product, on the retailer’s native 1-to-5 scale, rounded to one decimal place. Requires at least twenty reviews; below that threshold the category is marked not scored and excluded from the composite. This category is deliberately separate from any keyword-driven category so the headline signal of “what buyers rated this product overall” sits alongside the more granular keyword-based categories.

The 0 to 5 scoring scale

Every category is scored on a five-point scale, and we’ll only use whole and half points.

• 5 / 5 Excellent. Strongly net-positive reviewer commentary or best-in-class construction benchmark.
• 4 / 5 Good. Above-average net signal. Most buyers report a positive experience in this category.
• 3 / 5 Average. Meets the mainstream UK standard for the category. Net signal is roughly neutral.
• 2 / 5 Below average. Net-negative reviewer commentary or a construction type with below-average benchmark performance.
• 1 / 5 Poor. Strongly net-negative signal. A category the evidence says to be cautious about.

Where the review sample is too small to produce a reliable signal, you’ll see the category marked “not scored” and left out of the composite. We’d rather show you a gap than fill it with a guess. The evidence panel on the product page states the exact signal count and the threshold required to generate a score.

Where the data comes from

Every score traces back to one or more of the sources below, and we don’t make claims that run past what the model can see.

• Customer review text (keyword analysis). Aggregated review text from the retailer’s own product listing. The model scans each review for a curated list of category-specific keywords. Positive and negative keyword counts across the full sample determine the net signal percentage that maps to the five-point rubric. Drives comfort, heat retention, value, and (where reviewer commentary is sufficient) edge support and motion isolation.
• Customer star ratings (aggregate). The raw 1-to-5 star rating on every active owner review for the product, averaged across the full sample and rounded to one decimal place. Drives the customer sentiment category. The minimum sample is twenty reviews; below that the category is marked not scored.
• Manufacturer specification. Construction type (pocket spring, hybrid, memory foam, latex, open-coil), declared materials, firmness label, and dimension data. Used as a fallback signal for edge support and motion isolation where keyword evidence is limited.
• Retailer policy data. Published trial nights, manufacturer warranty term, and return policy on file for the retailer that lists the product. Drives the retailer guarantee category. Where no published policy is on file for the retailer, the category is marked not scored.

What the score can’t tell you

Nobody here has slept on any of it. What you’re reading is built from what other owners reported, which means it inherits every one of their blind spots along with their useful bits. Reviews skew towards the first few weeks of ownership, because that’s when people bother to write them, which is why durability leans on the older reviews in a sample rather than the average of all of them.

A high score just means the evidence points one way for most owners. It can’t tell you whether a mattress suits your weight, your sleeping position or the temperature you run at, and those three will decide your night far more than the composite will. Find the category that matches your problem, read that, and ignore the headline. That’s the honest way to use this site.

Conflict-of-interest disclosure

BedBoy is funded entirely by affiliate commission. When you click through one of our outbound links and buy a product, the retailer pays us a small percentage of the sale. Neither the existence of an affiliate relationship nor the size of the commission changes a BedBoy Score. It hasn’t and it won’t.

Brands can’t pay to appear on BedBoy. Brands can’t pay to be removed. Brands can’t vet or revise our scoring before it goes live. Where a page is paid placement (a sponsored post or advertorial), it’s labelled “Sponsored” at the top and bottom and is kept out of the scored programme entirely.

For the full breakdown of how affiliate links work and the networks we use, see our affiliate disclaimer.

Refresh cadence

The keyword signal extraction that drives the BedBoy Score runs automatically on a nightly cycle across the full active catalogue. As fresh customer reviews land on the retailer sites we import, the review pool grows and the signal counts update. A product that accumulates enough new reviews overnight to cross a scoring threshold will have an updated score the following morning.

Manufacturer specification data (construction type, materials, firmness label) gets updated when we hear about a change, which isn’t always as promptly as we’d like. Specification changes are more infrequent than review volume changes but have a direct effect on the construction-type fallback signals for edge support and motion isolation.

If a product is discontinued or pulled from the market we mark the page and stop refreshing the score. There’s no point scoring something you can’t buy.

Corrections

Factual errors get corrected at the top of the page, with the date on them, so you can see what moved and when. If a score moves up or down following a refresh, the page records both the new score and the date of the change. We don’t rewrite history and hope nobody noticed.

If you spot something that looks wrong, we’d genuinely rather hear about it than not. Email [email protected] with a link to the page.

Frequently asked questions

What is the BedBoy Score?

The BedBoy Score is a composite on a 0 to 5 scale, calculated as the unweighted mean of every category scored for that product. How many apply depends on the product type: ten for a mattress, eight for a bed frame, six for a headboard, duvet or kids bed. A mattress covers comfort, pressure relief, edge support, motion isolation, heat retention, durability, off-gassing, value, retailer guarantee and customer sentiment. The keyword-driven categories come from signal analysis of imported reviews, with construction-type benchmarks as a fallback where commentary is thin. Retailer guarantee comes from published retailer policy. Customer sentiment is the raw mean star rating. The per-category breakdown on every product page shows the signal counts behind each figure.

Does BedBoy physically test every mattress on the site?

No, and we don’t claim to. Nothing on BedBoy has been slept on by an editor. Every score is built from imported customer review signals, manufacturer specification data, retailer policy data and aggregated star ratings, which is a different thing from a hands-on review and is described that way throughout. The evidence panel on every product page shows the signal counts and the derivation method behind each figure, so you can see what any given score rests on.

How often is each BedBoy Score refreshed?

The keyword signal extraction, retailer guarantee pass, and customer sentiment pass all run nightly across the full catalogue. As new reviews arrive, the signal counts and the average star rating update and scores can move. A product that crosses a scoring threshold overnight because of new review volume will have an updated score by the following morning. Construction-type specification data and retailer policy data are updated whenever we become aware of a change.

Where does the review data come from?

Customer reviews on the retailer's own product listing, imported nightly. For the five keyword-driven categories the model scans each review for a curated list of category-specific positive and negative keywords; the net signal as a percentage of the review sample maps to a five-point score against a published rubric. For customer sentiment the raw 1-to-5 star rating on each active review is averaged across the full sample. Where the sample is too small to produce a reliable signal the category is marked "not scored" and excluded from the composite.

How is the retailer guarantee category scored?

Retailer guarantee is the average of three equally-weighted sub-scores. Trial length: 5/5 at 100+ nights, 4/5 at 60-99, 3/5 at 30-59, 2/5 at 14-29, 1/5 below 14. Warranty term: 5/5 at 10+ years, 4/5 at 5-9, 3/5 at 2-4, 2/5 at 1 year, 1/5 below. Return cover: free comfort exchange scores highest, free returns next, paid collection mid-band, no returns lowest. The evidence panel on every product page lists the exact trial length, warranty term, and return policy used in the calculation. Where no published policy is on file for the retailer, the category is marked not scored.

How is the customer sentiment category scored?

Customer sentiment is the raw mean star rating across every active owner review on the retailer’s product listing, on a 1-to-5 scale, rounded to one decimal place. The threshold for scoring is a minimum of twenty reviews; below that the category is marked not scored and excluded from the composite. This category sits alongside the keyword-driven comfort score so the headline signal of "what buyers rated this product" is visible separately from the more granular per-attribute commentary.

Does affiliate commission affect the BedBoy Score?

No. BedBoy is funded by affiliate commission on outbound retailer links, but neither the existence of an affiliate relationship nor the level of the commission affects the score. Brands can’t pay to appear on BedBoy, can’t pay to be removed, and can’t vet or revise the score before it goes live. Sponsored content is labelled and kept out of the scored programme entirely.

Why does a product show "not scored" for some categories?

A category is marked "not scored" when the underlying evidence is too thin to produce a reliable figure. For comfort, value, and heat retention that usually means the review sample is below the minimum signal count. For edge support and motion isolation it means both the keyword signal and the construction-type fallback are unavailable. For retailer guarantee it means we have no published policy on file for the retailer. For customer sentiment it means fewer than twenty reviews. We exclude these categories from the composite rather than assign a default score that would mislead the comparison.

Methodology changelog

• v1.4, 9 August 2026. Removed the Home tested / Store tested tier-badge taxonomy. No badge was ever rendered on a product page, so the section described a mechanism the site did not have. BedBoy makes no hands-on testing claim of any kind and the page now says so throughout. Rubric documentation corrected against the live category table: mattresses carry ten categories, not seven, with pressure relief, durability and off-gassing added in May and never written up; bed frames gained material. Headboard categories were repaired in the database, having been attached to the wrong product type, which left 86 headboards unscoreable. Bedroom furniture and sofa beds documented as universal-only.
• v1.3, 14 May 2026. Added explicit Tier badge taxonomy (Home tested / Store tested / no badge) and softened “Hands-On” phrasing to reflect that most pages on the site are scored from review and specification data only. Added Speakable schema across the rubric and scale blocks for AI-assistant readability. Added this changelog.
• v1.2, 12 May 2026. Customer sentiment minimum-sample threshold raised from ten reviews to twenty. Retailer guarantee scoring split into three equally-weighted sub-scores (trial length, warranty term, return cover) with published thresholds.
• v1.1, 22 April 2026. Heat-retention category added to the mattress rubric. Construction-type fallback formalised for edge support and motion isolation where keyword evidence is limited.
• v1.0, 2 April 2026. Initial published methodology: seven scoring categories, 0-to-5 five-point scale, nightly refresh cadence, conflict-of-interest disclosure.
