Short answer: A split king mattress in Canada is two Twin XL mattresses, each 38 x 80 inches (96.5 x 203 cm), placed side by side for a combined 76 x 80 inch (193 x 203 cm) surface, the exact footprint of a standard king, and it is the required configuration for dual adjustable bases.
Hamuq builds a split king from two Original Hybrid Twin XLs at $879 CAD each ($1,758 CAD for the pair), or two Organic Hybrid Twin XLs at $1,589 CAD each ($3,178 CAD for the pair). Both are made in Canada with a 120-night risk-free trial and a 15-year warranty. Expect the pair to cost more than one king mattress; the honest math is in the cost table below.
A split king solves one specific problem: two people sharing a king-width bed who need different things from it. Different firmness, different sleep positions on an adjustable base, or simply immunity from a partner's tossing. It fits every standard king frame, and it is the only configuration that works when each side of the bed moves independently. If you are still comparing sizes in general, start with the full Canadian mattress size chart or our guide to the best mattress in Canada, then come back here for the split-specific measurements and price math.
What size is a split king mattress in Canada?
A split king measures 76 inches wide by 80 inches long (193 x 203 cm) in total, made up of two Twin XL mattresses of 38 x 80 inches (96.5 x 203 cm) each. The combined footprint is identical to a standard king, so it fits the same frames, the same rooms, and the same king flat bedding. Plan a bedroom of roughly 12 x 12 feet (3.7 x 3.7 m) or larger so you keep walking clearance on three sides.
| Size | Width x length (in) | Width x length (cm) | Per sleeper width | Typical use |
|---|---|---|---|---|
| Split King (2 x Twin XL) | 76 x 80 | 193 x 203 | 38 in (96.5 cm) | Couples, adjustable bases |
| Twin XL (one half) | 38 x 80 | 96.5 x 203 | 38 in (96.5 cm) | One side of a split king |
| Standard King | 76 x 80 | 193 x 203 | 38 in (96.5 cm) | Couples, one mattress |
| California King | 72 x 84 | 183 x 213 | 36 in (91.5 cm) | Sleepers over 6 ft 4 in |
| Queen | 60 x 80 | 152 x 203 | 30 in (76 cm) | Couples in smaller rooms |
Split king vs standard king: what is the difference?
A split king and a standard king occupy the same 76 x 80 inch footprint; the difference is that a split king is two independent mattresses, which allows different firmness per side, independent adjustable-base movement, and near-zero motion transfer across the seam. The trade-offs are a centre seam you can feel near the middle, two fitted sheets instead of one, and a higher combined price than a single king mattress.
| Factor | Split King | Standard King |
|---|---|---|
| Total footprint | 76 x 80 in (193 x 203 cm) | 76 x 80 in (193 x 203 cm) |
| Mattress count | 2 (Twin XL each) | 1 |
| Firmness per side | Can differ | Identical |
| Dual adjustable base | Compatible | Not compatible |
| Motion transfer across the bed | Near zero at the seam | Depends on mattress build |
| Centre seam | Yes, bridgeable with a gap filler | None |
| Fitted sheets needed | 2 x Twin XL | 1 x King |
| Moving and stairs | Easier, two lighter boxes | One large, heavier mattress |
| Hamuq price, Original Hybrid | $1,758 CAD (2 x $879 CAD) | $1,189 CAD |

What base or frame fits a split king?
A split king fits any base with a standard king footprint: a king platform bed, a king frame with a centre-supported slat system, two Twin XL foundations placed side by side, or two Twin XL adjustable bases. Hamuq does not sell adjustable bases, but both Hamuq hybrids are built to flex on one; the pairing rules are in our adjustable base compatibility guide. Whatever you choose, the support surface has to meet the warranty rules in our bed frame and slat spacing guide, because a sagging base voids most Canadian mattress warranties, Hamuq's included.
| Base type | Fits a split king? | Note |
|---|---|---|
| King platform bed | Yes | Solid or slatted deck, king footprint |
| King frame with slats | Yes | Centre rail and leg required at king width |
| 2 x Twin XL adjustable bases | Yes, the intended pairing | Each side moves independently |
| 2 x Twin XL foundations | Yes | Strap the bases so they do not drift apart |
| 1 x King box spring | Yes for flat use | No independent movement possible |
| Queen or double frame | No | Footprint is too narrow for 76 in |
How much does a split king mattress cost in Canada?
A split king costs the price of two Twin XL mattresses, which in Canada runs higher than one king mattress of the same model. At Hamuq, two Original Hybrid Twin XLs come to $1,758 CAD, which is $569 CAD (48 per cent) more than the one-piece Original Hybrid king at $1,189 CAD. Two Organic Hybrid Twin XLs come to $3,178 CAD, which is $679 CAD (27 per cent) more than the Organic king at $2,499 CAD. You are paying that premium for independent firmness and adjustable-base compatibility, so only pay it if you will use one of those two things.
| Configuration | Original Hybrid | Organic Hybrid |
|---|---|---|
| Split King (2 x Twin XL) | $1,758 CAD | $3,178 CAD |
| Per Twin XL half | $879 CAD | $1,589 CAD |
| Standard King (one piece) | $1,189 CAD | $2,499 CAD |
| Split premium over king | $569 CAD (48 per cent) | $679 CAD (27 per cent) |
| Queen, for reference | $999 CAD | $1,999 CAD |

The Original Hybrid half is a CertiPUR-US certified foam and pocket coil build at a medium-firm feel; the Organic Hybrid half uses GOLS certified Dunlop latex, a GOTS certified cotton cover, and a fiberglass-free New Zealand wool fire barrier at a firm 7.5 out of 10. You can also mix one of each if one sleeper wants latex and the other wants foam; both halves are the same 38 x 80 inch size. To be fair to the field, Endy and Douglas also sell Twin XL sizes you can pair the same way, and Douglas sells its own adjustable base if you want mattress and base from one brand. Compare trial lengths and per-pair totals before you decide.
What bedding fits a split king?
A split king uses two Twin XL fitted sheets, two Twin XL mattress protectors, and one king-size flat sheet, duvet, and duvet cover across the top. The top layer is what visually joins the two halves into one bed. Hamuq does not sell a dedicated split king sheet set, so buy the fitted layer as Twin XL pieces; the king-size duvet sizing rules are in our Canadian duvet size guide.
| Bedding item | Size to buy | Quantity | Hamuq price |
|---|---|---|---|
| Fitted sheet | Twin XL (38 x 80 in / 96.5 x 203 cm) | 2 | Not sold as split set |
| Mattress protector | Twin XL | 2 | $89 CAD each |
| Flat sheet | King | 1 | In king sheet set, $169 CAD |
| Duvet insert | King | 1 | $399 CAD |
| Duvet cover | King | 1 | $200 CAD |
| Gap filler / bed bridge | King length (80 in / 203 cm) | 1, optional | Not sold by Hamuq |

What size is a split king mattress in Canada?
A split king in Canada measures 76 x 80 inches (193 x 203 cm) in total, made of two Twin XL mattresses at 38 x 80 inches (96.5 x 203 cm) each. The combined footprint is identical to a standard king, so it fits any king frame, king room layout, and king-size top bedding.
Is a split king the same size as a standard king?
Yes, a split king and a standard king share the exact same 76 x 80 inch (193 x 203 cm) footprint. The difference is construction, not size: a split king is two independent Twin XL mattresses, which allows different firmness per side and independent movement on dual adjustable bases, while a standard king is one mattress.
Do two Twin XL mattresses make a split king?
Yes, two Twin XL mattresses placed side by side form a split king. Each Twin XL is 38 x 80 inches (96.5 x 203 cm), so the pair spans 76 x 80 inches, the standard king footprint. Both Hamuq hybrids are sold in Twin XL, at $879 CAD for the Original Hybrid and $1,589 CAD for the Organic Hybrid per half.
What sheets fit a split king bed?
A split king takes two Twin XL fitted sheets on the bottom and king-size bedding on top: one king flat sheet, one king duvet, and one king duvet cover. Use two Twin XL mattress protectors, one per half. Dedicated split king sheet sets exist at some retailers, but two Twin XL fitted sheets plus standard king top bedding does the same job.
Is a split king more expensive than a regular king?
Yes, a split king usually costs more because you are buying two mattresses instead of one. At Hamuq, two Original Hybrid Twin XLs total $1,758 CAD versus $1,189 CAD for the one-piece king, a $569 CAD premium, and two Organic Hybrid Twin XLs total $3,178 CAD versus $2,499 CAD for the Organic king. The premium buys independent firmness and adjustable base compatibility.
Does Hamuq sell a split king mattress?
Hamuq sells a split king as a pair of Twin XL mattresses rather than as a single SKU. Order two Original Hybrid Twin XLs, two Organic Hybrid Twin XLs, or one of each to mix foam and latex sides. Every half ships with the 120-night risk-free trial, free courier pickup with a full refund, and the 15-year warranty, and both are made in Canada.
Final word
A split king is the right call when the bed has to do two different jobs at once: two firmness preferences, or an adjustable base on at least one side. It costs a real premium over a one-piece king ($569 CAD more on the Original Hybrid, $679 CAD more on the Organic Hybrid), so if you sleep flat and agree on firmness, buy the one-piece king and keep the difference. Either way the footprint, the frame, and the room math are identical.
