Search "best memory foam mattress in South Africa" and you'll drown in sales pages, each one swearing they're the best. So let's do something different. An honest comparison — the real brands, real prices, real pros and cons. Including the ones that beat us at certain things.
Full disclosure up front: this guide is published by Mr Mattress. We could've written a page that says we're perfect and everyone else is rubbish. We didn't. We held ourselves to the same test as everyone else, and where another brand genuinely does something better, we say so. That's the only kind of guide worth reading — and the only kind worth trusting.
How we judged them
Five things separate a good memory foam mattress from an expensive mistake:
- Foam density. High density holds its shape for years. Low density feels great in the shop and sags in a year. This is the whole game.
- SABS approval. Proof the foam was tested and passed, not just marketed.
- Support. Does it keep your spine aligned, or do you sink and ache?
- Try-before-you-commit. A home trial means you're not gambling.
- Honest pricing. What you pay for the foam, not for the brand name on the label.
A note on prices: these are 2026 starting and typical figures to help you compare, not live quotes. Prices move and depend on size, so always check the current price before you buy.
The short version
| Brand | Best for | Starting price (approx.) | The standout |
|---|---|---|---|
| Mr Mattress — Active Foam | Best value all-rounder | From R3,399 (on sale; R4,999 normally) | SABS-approved 40 kg/m³ foam at a factory-direct price |
| Cloud Nine | Best-known name | Queen approx. R4,000–R7,200 | Endorsed by the SA Society of Physiotherapy |
| Sloom | Couples & the undecided | Queen approx. R10,000 | Adjust the firmness yourself, at home |
| Genessi (now Restonic iDream) | Heavier sleepers | Premium, approx. R10,000+ | Heavy-duty, high weight-capacity foam |
Mr Mattress — Active Foam (best value all-rounder)
Our own bed, so judge us hard. The Active Foam is built around a SABS-approved 40 kg/m³ high-density orthopaedic core, topped with a pressure-relief comfort layer. It's the bed we built our name on — the same obsession with foam that earned us the 2017 World Record for the strongest bed, Foam Mattress Manufacturer of the Year in 2018, and an endorsement from DESTEA.
The good: Real high-density foam at a factory-direct price, because there's no retailer markup in the middle. SABS-approved. A 180-night test guarantee, so you're not gambling. SA-made, same-day delivery in our areas.
The honest catch: We're not a luxury hotel brand and we don't pretend to be. If you want a famous name on the label or a plush five-layer pillow-top, we're not that. We're the bed that does the actual job — spine support that lasts — without the premium price.
Cloud Nine (the best-known name)
Cloud Nine has been making beds in South Africa since 1968, and they've earned their reputation. Their open-cell memory foam is genuinely breathable, and they carry an endorsement from the South African Society of Physiotherapy — a real, credible trust signal.
The good: Trusted, widely stocked, physio-endorsed, and the breathable foam helps with our hot summers.
The honest catch: You'll usually buy through a retailer, which means a markup between you and the factory. The top of their range climbs well past R7,000 for a queen. A strong, safe choice — you just pay for the name and the middleman.
Sloom (best for couples and the undecided)
Sloom cracked a real problem: how do you buy a mattress online when you don't know your firmness? Their modular design lets you adjust the feel at home — softer, firmer, or a different firmness on each side for couples. Add a 100-night trial and a 25-year service warranty, and the risk is genuinely low.
The good: Adjust firmness yourself, brilliant for couples who can't agree, proper home trial, strong warranty.
The honest catch: Around R10,000 for a queen, it's roughly three times our entry price. You're paying for the clever modular system and the slick online experience. If you already know you want firm orthopaedic support, you can get it for a lot less.
Genessi / Restonic iDream (best for heavier sleepers)
Genessi built its name on heavy-duty, high-density orthopaedic foam with serious weight capacity — a solid pick for couples or heavier-set sleepers who've worn out softer beds. Worth knowing: the Genessi name is being folded into Restonic's iDream range, so you'll increasingly find it under that branding.
The good: Durable, high weight-capacity foam built to take a beating without sagging.
The honest catch: It sits at the premium end of the market, and with the move to Restonic, the "Genessi" badge is becoming harder to pin down. Great foam — just be clear on exactly which model and price you're getting.
So which should you buy?
Be honest about what you actually need.
- Want a famous name and don't mind the markup? Cloud Nine.
- Can't agree on firmness with your partner, and budget isn't the issue? Sloom.
- Heavier-set and need maximum durability? Genessi / Restonic.
- Want SABS-approved high-density foam that supports your spine and lasts for years, without paying double for a label? Mr Mattress Active Foam.
For most South Africans, that last one is the sweet spot. Same job as the premium beds. A fraction of the price. And a 180-night guarantee so you can prove it to yourself.
