Floor Bed Mattress Sizes South Africa: Which Mattress Fits Your Frame
You have bought the frame, or you are about to, and every single one of them says the same thing: mattress not included. This page exists to answer the next question in one table.
Measure first. Inside edge to inside edge, both ways, in centimetres. Frame makers change models and a 5cm error is the difference between snug and a gap a small arm fits into.
| Floor bed frame | Mattress size it takes | Frame price | The Mr Mattress size that fits |
|---|---|---|---|
| WoodStyle Montessori Floor Bed (Cape Town, birch) | 140 x 70cm | R4,350 | Comfort Foam Toddler 140 x 70, R1,699. This is the only size we cut at 140 x 70 |
| WoodStyle Montessori Floor Bed, single | 188 x 91cm | R4,990 | Active Foam Single, R3,399 |
| Declan and Leah Montessori Floor Bed (SA pine) | Single, Three Quarter or Double | R3,800 to R6,450 | Active Foam Single R3,399, Three Quarter R3,799, Double R4,299 |
| Bambino Boutique Floorbed Star Child (SA pine) | 190 x 94cm inside | Ask the maker | Active Foam Single, R3,399. A 92 x 188 mattress sits inside 190 x 94 with a small gap on each side |
| Lifeforce Living Classic Montessori | Single, removable rails | Ask the maker | Active Foam Single, R3,399 |
| Presidential Royal Kids floor bed with drawers | 200 x 90cm | Ask the maker | That is an extra length frame. The Active is not cut at 200cm, so use the Revive Single Extra Length, R5,879 |
| Takealot Montessori Brite or Forwood, bed with mattress | Toddler, mattress included | Bundle | The included pad is an unbranded foam sheet. If you keep the frame, the Comfort Foam Toddler 140 x 70 at R1,699 is the upgrade |
| Facebook Marketplace or Gumtree, second hand or small maker | Measure the inside, it is usually 140 x 70 or single | R1,000 to R6,300 | Measure inside edge to inside edge, then match it to the two sizes above |
Frame names, sizes and prices were read off each maker's own website on 15 September 2026. Measure your own frame before you order, because makers change models.

Why a gap matters
A mattress should sit snug against the inside of the frame. A gap between the mattress and the rail is somewhere an arm or a leg can go, and on a floor bed the child is turning against that edge all night. If your frame measures oddly, phone us. We cut custom sizes every week for caravans and bakkies and a floor bed is an easier job than either.
The age rule, said plainly. A mattress on or near the floor is for a child of 12 months and older.
Under 12 months the American Academy of Pediatrics, Red Nose and the Lullaby Trust all say the same thing: a cot, a bassinet or a play yard, and nothing else. Some Montessori writers suggest a floor bed from crawling, at about 9 months. We follow the safe sleep bodies, not the furniture trend, so we will not sell you a floor mattress for a baby under one. Between 12 and 18 months it can work, but only in a properly child proofed room, and speak to your clinic sister or paediatrician first.
What you get from us that a frame maker cannot give you.
SABS approved foam and a Confidence in Textiles cover fabric. A 365 night trial, which is a full year to decide, against the 100 nights the big bed chains offer and the nothing at all a furniture maker offers on a mattress. A 10 year warranty. Free delivery anywhere in South Africa. Made in our own factory, so there is no importer in the middle.
