Who a king mattress suits
A king is essentially two single mattresses of width in one bed: 183 cm across against a single's 91 cm. That means each of two adults gets 91.5 cm of personal space, slightly more than a child gets on an entire single mattress. Couples who find even a queen crowded, restless sleepers whose turning wakes a partner, and families whose children or pets migrate into the bed at night are the classic king buyers.
Taller and larger framed sleepers also gravitate to king. The length is the same 188 cm as every standard South African size, but the extra width means a big sleeper can spread out, shift position and sleep slightly diagonally without running out of mattress. If your main bedroom has the space, a king is the most comfort per rand you can add to a shared bed. If it does not, the queen mattress is the sensible step down.
King mattress prices in South Africa
These are live Mr Mattress prices, checked on 19 July 2026. Two of the four ranges are currently listed in king size online: Revive Memory Foam and the Hybrid, both carrying the 10 year written warranty. Comfort Foam and Active Foam stop at queen size online.
| King (183 x 188 cm) | Mattress only | Base set | Warranty |
|---|---|---|---|
| Comfort Foam | Not listed in king | Not listed in king | 3 years |
| Active Foam | Not listed in king | Not listed in king | 10 years |
| Hybrid | Base set only online | R7,999 | 10 years |
| Revive Memory Foam | R8,999 | R9,999 | 10 years |
Worth noticing: the complete Hybrid king base set at R7,999 costs less than the Revive king mattress alone, which makes it the strongest value route into a king bed if you also need a base. The Hybrid pairs a pocket spring support core with a thick foam comfort layer and reinforced edges, the pick for heavier sleepers and spring feel. Revive Memory Foam is the contouring choice for side and combination sleepers. The mattress firmness guide helps you pick between the two feels.
Will a king bed fit your room?
Give a king bed about 3 metres of width to breathe: 183 cm of bed plus roughly 60 cm of walking space on each side. A bedroom of around 3.5 x 3.5 metres carries a king comfortably with furniture; anything much smaller and the bed starts to dominate the room, which is when most buyers are happier with a queen. Measure the wall the headboard will sit against and the walkways before ordering, not after.
Base pairing is straightforward: online, king is sold as complete base sets, either the Hybrid king base set at R7,999 or the Revive Memory Foam king base set at R9,999, so the correct solid platform arrives with the mattress and no box spring is needed. Delivery of a king costs nothing extra anywhere in South Africa: Free State customers: usually 1 to 3 working days; national orders: 3 to 7 working days depending on your area.
Frequently asked questions
What size is a king mattress in South Africa?
A king mattress in South Africa measures 183 x 188 cm, which is very close to two single mattresses (91 x 188 cm each) side by side. It is 31 cm wider than a queen. Like all standard South African sizes, it is 188 cm long, so the gain is all in width.
How much does a king mattress cost in South Africa?
At live 19 July 2026 pricing, the Hybrid king base set is R7,999 and the Revive Memory Foam king is R8,999 as a mattress only or R9,999 as a complete base set. Both carry a 10 year written warranty, free delivery anywhere in South Africa and the 365 night home trial.
Which Mr Mattress ranges come in king size?
Two ranges are listed online in king size: Revive Memory Foam, as a mattress only or a base set, and the Hybrid with its pocket spring support core, sold as a complete king base set. Comfort Foam and Active Foam currently stop at queen size online, so king shoppers choose between those two.
What room size do I need for a king bed?
Give a king bed about 3 metres of width to breathe: the bed itself is 183 cm wide, and 60 cm of walking space each side keeps the room usable. A bedroom of roughly 3.5 x 3.5 metres is comfortable, and anything smaller usually suits a queen better than a king.
Is a king bed worth it over a queen?
If your room and budget allow it, yes: 31 cm of extra width is the difference between sharing space and each sleeper having room to spread out. It makes the biggest difference for restless sleepers, larger or taller sleepers, and families whose children or pets end up in the bed at night.
