Comfy Mattress, a mattress shop in Algiers, scores 100/100/100/100 on Google PageSpeed. Here are the real technical choices behind that score, explained without jargon.
What does a PageSpeed score actually mean?
The Comfy Mattress website, a mattress shop in Algiers, scores 100 out of 100 on Google PageSpeed. Not just on speed: 100 on performance, 100 on accessibility, 100 on best practices, and 100 on SEO, on both mobile and desktop.
A lot of people think a good PageSpeed score is just a technical number for developers. In truth, it is simple: it measures what your customers actually feel when they open your site on their phone. A high score means a page that loads fast, stays readable for everyone, and is easy for Google to find.
Here is, in plain words, how we got there, and why it matters for a business like Comfy Mattress.
Comfy Mattress, before the website
Comfy Mattress is a mattress, pillow and bedding shop in Algiers, run by a single owner. The shop sits in Sidi M'hamed, just off the main Hassiba Ben Bouali avenue.
Before we worked together, the business had no online presence at all: no website, no Google Business Profile, no social media. Customers across Algiers were looking for a good mattress and never came across the shop. A good street location is not enough if no one can find you on Google.
Why speed matters more than people think
In Algeria, most customers open a site from their phone, often on an average connection. If a page takes more than two or three seconds to appear, many visitors leave before they see a single product.
Google knows this too. Fast sites have a better chance of ranking well in search results. A slow site does not just lose impatient visitors: it loses visibility too, month after month.
The proof, in real numbers
This is the real Google PageSpeed Insights report for the Comfy Mattress site, not a marketing promise. 100 on performance, 100 on accessibility, 100 on best practices, 100 on SEO, on mobile and desktop, plus 3/3 on Agentic Browsing, the score that measures whether a site is ready for AI answer engines.
The site just launched, so Google does not yet have enough real visits to show its field data ("Discover what your real users are experiencing"). That does not change the lab score above: this field data will arrive over time, as real visits build up.
Performance 100 · Accessibility 100 · Best Practices 100 · SEO 100 · Agentic 3/3
A site that sends almost no unnecessary code to the phone
Many sites send too much JavaScript to a visitor's phone, code the phone then has to process before it can show anything. On an average connection, this shows: the page stays blank, then loads in fits and starts.
The Comfy Mattress site is built in Next.js to send as little code as possible upfront. The page arrives already ready on screen, without waiting for the phone to do all the work. That is one reason it loads fast, even on an average 4G connection.
Mattress photos that weigh less, without losing quality
A bedding site lives on its photos: mattresses, pillows, bedrooms. Photos are often what slows a site down the most, when they are not prepared correctly.
Next.js automatically shrinks and resizes each photo to fit the screen requesting it, with no visible loss of quality. A customer on their phone gets an image sized for their phone, not the full-size version meant for a large desktop screen.
Fewer moving parts, fewer reasons to slow down
On WordPress or PrestaShop, every added feature often means one more plugin. Every plugin is more weight, and sometimes a source of conflict with the others.
The Comfy Mattress site is custom-built, styled with Tailwind CSS, without stacking dozens of plugins. Fewer moving parts means fewer reasons to slow down, and simpler upkeep over time.
Did this actually change anything for Comfy Mattress?
The owner of Comfy Mattress left this review after launch: "The site looks modern and professional, and it loads super fast, even on my phone, which matters a lot to us and our customers." (5-star review)
That is not just a feeling. It is exactly what the PageSpeed score measures: the speed a real visitor experiences, on a real phone.
A score of 100 is not enough on its own, and that is worth saying plainly
A fast site helps, but it does not do everything. Comfy Mattress just launched: its local ranking builds over time, as the site, the Google Business Profile and social media work together.
Speed is a solid foundation, not a magic wand. It gives the site every chance, but real sales also come from good SEO, real product pages, and a well-kept Google Business Profile.
What about your business?
This level of speed is not reserved for big brands. It is the result of a technical choice (Next.js), well-prepared photos, and a site built without excess. See the full report and the Comfy Mattress story on our portfolio page, or see how we build this kind of site on our web design page.

Frequently asked questions
What does the Google PageSpeed score actually measure?
It measures four things on a 0-100 scale: performance (real-world speed), accessibility (whether the site is usable by everyone), best practices (technical quality), and SEO (search fundamentals). Comfy Mattress scores 100 on all four, on mobile and desktop.
Does a 100/100 score guarantee more sales?
No, not on its own. Speed helps visitors stay and helps Google rank the site well, but sales also depend on content, local SEO, and the Google Business Profile. It is a foundation, not a guarantee.
Can a WordPress site also reach 100/100?
It is possible, but it takes much more tuning and upkeep, especially with plugins. Next.js starts with a natural speed advantage, which makes a 100/100 score easier to reach and easier to keep over time.
How long does it take to build a site this fast?
It depends on the number of pages and products. The Comfy Mattress site, with several product lines and bilingual content, was delivered in a few weeks. We always give a clear timeline before we start.
