Sloom vs Mr Mattress: Honest Mattress Topper Comparison (2026)
Sloom vs Mr Mattress: Honest Mattress Topper Comparison (2026)
Quick answer: Sloom's topper is 5cm of memory foam under a 500gsm knit cover, at prices noticeably higher than ours across every size, for example R3,400 against our R2,599 to R2,799 on a Queen. Ours is 7cm, 40% thicker, with a quilted top and a fitted border that wraps the mattress like a fitted sheet, a published 30 density, and a 365 night trial that covers everything, including the foam not suiting you. Sloom's return window is 7 days with a 10% fee once tried. If Sloom's brand or the heavier cover weight is what matters most to you, buy theirs. If you want more foam for less money, a better construction, and a full year to actually test it, buy ours.
Both memory foam, different depth and price
Sloom, best known for its modular mattress, also sells a standalone memory foam topper: 5cm of visco-elastic foam under a 500gsm knitted antibacterial cover, backed by a 2 year guarantee against faults. Mr Mattress makes ours 7cm thick at a published 30 density, with a quilted top and a fitted border that wraps the mattress like a fitted sheet, and it ships flat and folded rather than rolled, so there is no wait for it to expand.

Where Sloom genuinely wins, buy theirs instead if this is you
- Brand recognition. Sloom is a well known name from its modular mattress, which carries over into trust in the topper. If that reputation matters more to you than the spec sheet, buy theirs.
- Cover weight. A 500gsm knit is a heavier, denser cover than most toppers use.
- King+ sizing options. Sloom lists a dedicated Cape Town King (200 x 214cm) size that few other brands stock as standard.
Where Mr Mattress wins
- Price. On every size we checked, ours costs less, often R700 to R900 less on the same size.
- Thickness. 7cm against Sloom's 5cm, 40% thicker.
- Quilted top. Ours has a quilted finish. Sloom does not describe its cover as quilted.
- Fitted border. Ours wraps around the mattress like a fitted sheet, so it stays in place. Sloom does not publish details on how its topper is finished at the edge.
- Published density. We print 30 density. Sloom does not publish a density figure for its foam.
- 365 night trial. Sloom's own return policy applies a 10% fee once a topper has been tried, with a 7 day window. Ours gives a full 365 nights with no fee, covering any reason including the foam flattening.
- No roll crease. Ours ships flat and folded, not rolled.
- Custom sizes. We cut toppers to order for caravans, bakkies and sleeper couches.
So which one should you buy?
Buy the Sloom topper if you already trust the Sloom brand from their mattress, want the heavier 500gsm cover, or need their Cape Town King size. Buy the Mr Mattress topper if you want more foam for less money, a quilted top and fitted border, a published density figure, or a full 365 nights to test it with no fee if you change your mind.
