EMMA Zero Gravity, Origin and MR. LIVING are three options for Taiwan shoppers replacing a mattress while keeping their existing bed frame. All three use pocket springs, but their comfort layers differ: EMMA includes a gel grid, Origin uses a latex comfort layer, and MR. LIVING uses a memory-foam-led design. Lunio Gen4, NITORI N-SLEEP NF004 and IKEA VALEVÅG bring other constructions or firmness choices into the comparison. The shortlist below explains these differences alongside the practical question of fitting a replacement to the existing frame.
The six recommendations cover selected double-bed versions and are not ranked by quality. Product details come from Taiwan manufacturers or official stores, rather than a shared laboratory test. Sizes below identify the versions being compared; the right dimensions depend on the household’s own bed frame. Measurements are nominal width × length × thickness, so a matching size label alone does not guarantee fit.
Mattress Comparison
| Mattress | Size (cm) W × L × H |
Construction | Existing frame considerations |
|---|---|---|---|
| EMMA Zero Gravity | 152 × 188 × 27 | AirGrid gel grid, foam layers and AeroFlex pocket springs | Check the 27 cm profile and required base support. |
| Origin Natural Latex Pocket Spring Mattress | 152 × 188 × 27 | Latex comfort layer and pocket springs | The listed ±2 cm tolerance is not an installation-gap requirement. Confirm fit with the supplier. |
| MR. LIVING Cooling Memory Foam Mattress | 152 × 188 × 25 | Memory foam, additional foam and pocket springs | Lower listed profile than the 27 cm models; still 152 cm wide. |
| Lunio Gen4 | 150 × 188 × 24 | Layered latex and foam without springs | Check side gaps and confirm the dimensional tolerance. |
| NITORI N-SLEEP NF004 | 150 × 188 × 22.7 | Rearrangeable C-CORE polyester inserts | Approximate dimensions; confirm the selected model’s tolerance and base compatibility with the supplier. |
| IKEA VALEVÅG | 150 × 190 × 24 | Pocket springs, five comfort zones and a foam top layer | Check the 190 cm length; IKEA specifies a mattress base or non-adjustable slatted base. |
Dimensions are nominal width × length × thickness for the selected versions. Confirm actual fit, dimensional tolerances and base requirements with the supplier.
1 EMMA Zero Gravity
EMMA’s Taiwan Zero Gravity listing specifies an AirGrid gel grid, foam layers and AeroFlex pocket springs, with a standard-double size of 152 × 188 × 27 cm. It is an option for a household replacing a spring mattress and interested in a grid-based comfort layer.
Keeping the frame does not necessarily preserve the height of the bed. Buyers replacing a thinner mattress should compare the 27 cm profile with the old mattress and the remaining visible headboard. The AirGrid layer offers a construction difference within this size group, but the recommendation depends on the frame’s usable opening and supporting surface accommodating the complete mattress.
2 Origin Natural Latex Pocket Spring Mattress
Origin’s Taiwan natural-latex pocket-spring mattress measures 152 × 188 × 27 cm in the standard-double version. Its construction combines a latex comfort layer with pocket springs, giving buyers a latex-containing option with spring support. Origin also lists normal dimensional variation of ±2 cm. This tolerance is not a required installation gap and does not guarantee a fit in a tightly enclosed frame. Ask the supplier to confirm compatibility with your frame and base before ordering.
Within the 152 × 188 cm group, this provides a latex-containing alternative without changing the listed 27 cm thickness. Buyers can compare the comfort-layer combination while asking about the required base. For a household whose main concern is lowering the bed surface, however, this model does not offer the lower listed profile of the 25 cm option below.
The latex label also appears on Lunio Gen4, but the two differ in construction and footprint. Origin combines a latex comfort layer with pocket springs at a 152 cm width; Lunio uses a layered latex-and-foam build at 150 cm. A preference for latex therefore leaves two separate decisions: the support construction and the footprint the existing frame can accommodate.
3 MR. LIVING Cooling Memory Foam Mattress
MR. LIVING’s standard-double cooling memory-foam mattress measures 152 × 188 × 25 cm and combines memory foam, additional foam and pocket springs. It belongs on the shortlist for buyers considering a memory-foam comfort layer who also want a lower listed profile than the two 27 cm options.
The nominal 2 cm difference is worth checking where headboard exposure or bed height matters, though it is not a measured difference between delivered mattresses. Despite its memory-foam product name, this model includes pocket springs and should not be mistaken for an all-foam mattress. Its lower listed profile concerns thickness only: the width remains 152 cm.
A practical comparison starts with the current sleeping surface measured from the floor, alongside the old mattress thickness. That gives the household a reference for whether a replacement would raise or lower the bed on the same platform. The preferred result is a usable bed height, not simply the thinnest mattress in the shortlist.
4 Lunio Gen4
Lunio Gen4 is a layered latex-and-foam mattress with a Taiwan double specification of 150 × 188 × 24 cm. It offers a spring-free alternative for shoppers evaluating a 150 cm-wide mattress, rather than assuming a 152 cm-wide model will fit.
Its 188 cm length makes NITORI NF004 a closer dimensional comparison than the 190 cm-long IKEA version below. Lunio offers a different material combination from NF004’s C-CORE inserts. The 150 cm width is not automatic permission to use it inside a frame intended for 152 cm: any remaining gap and the supporting surface still need checking. Preference for latex also needs to be assessed in the complete mattress, not inferred from one material. For a closely fitted frame, ask Lunio to confirm the applicable dimensional tolerance for the selected Gen4 size before ordering.
5 NITORI N-SLEEP NF004
The Taiwan double version of NITORI N-SLEEP NF004 measures approximately 150 × 188 × 22.7 cm. Its C-CORE polyester inserts can be rearranged inside the mattress. This makes it worth considering for buyers interested in internal configuration changes as well as a lower listed mattress height.
NF004 and Lunio Gen4 share a nominal 150 × 188 cm footprint, with listed thicknesses of 22.7 cm and 24 cm respectively. These are approximate dimensions. Confirm the selected model’s dimensional tolerance with the supplier rather than treating the listed figures as exact installed heights. Rearranging the inserts changes the mattress internally. For an adjustable bed base, ask the supplier whether NF004 is suitable.
6 IKEA VALEVÅG
The super-firm Taiwan version of IKEA VALEVÅG measures 150 × 190 × 24 cm. It combines pocket springs, five comfort zones and a foam top layer. This version addresses shoppers seeking a super-firm spring model whose frame can accommodate the 190 cm length.
That extra length distinguishes it from Lunio and NITORI despite the shared 150 cm width. Replacing an 188 cm-long mattress with this version needs an actual clearance check. IKEA’s super-firm description identifies the selected variant, not a standardized firmness score against the other five models. A different VALEVÅG size or firmness should be treated as a separate buying option.
IKEA specifies a mattress base or a non-adjustable slatted bed base for this model. A household retaining an electrically adjustable frame should resolve that base requirement before ordering VALEVÅG.
Choosing between the six recommendations
For a confirmed-compatible 152 × 188 cm setup, compare EMMA for its grid-and-foam comfort layers, Origin for its latex comfort layer, and MR. LIVING for memory foam with a 25 cm profile. Each uses pocket springs. Within the 150 × 188 cm pair, compare Lunio’s layered construction with NF004’s rearrangeable inserts. Consider VALEVÅG separately where 150 × 190 cm and a super-firm specification suit the purchase.
Measure the frame’s usable opening and inspect the surface supporting the mattress. Sleep Foundation’s guide to bed-frame types highlights mattress dimensions and frame height as purchase considerations and describes different supporting designs. EMMA’s Taiwan mattress comparison adds a size-based screening framework. Ask each supplier about suitable support and slat spacing rather than applying one rule to every model.
For example, EMMA’s Taiwan warranty terms exclude length and width variations within ±2 cm, height variations within ±1 cm, and damage from an unsuitable base. These exclusions are not recommended installation clearances. For a tight-fitting frame, ask the supplier about the selected size and base before ordering; then compare the compatible models for feel and review delivery and return terms. After installation, EMMA’s home mattress-testing guide offers practical comfort checks with the bed frame, bedding and room conditions kept consistent.
Frequently Asked Questions
Can I replace my mattress without changing my existing bed frame?
Yes, provided the new mattress fits the frame and the base meets the mattress manufacturer’s support requirements. Measure the usable opening, inspect the supporting surface and check any slat-spacing requirements. EMMA Zero Gravity, Origin and MR. LIVING are the 152 × 188 cm options compared here; each still needs a compatibility check.
Are all double mattresses in Taiwan the same size?
No. The selected models in this article have three nominal footprints: 152 × 188 cm, 150 × 188 cm and 150 × 190 cm. A shared double-bed label does not make them interchangeable. Compare the exact width and length of the selected version with your frame’s usable opening before ordering.
Can I put a 150 cm-wide mattress on a frame intended for 152 cm?
Possibly, but the narrower width alone does not establish compatibility. Check the remaining side gaps, the mattress length and how the base supports the mattress. A 150 × 190 cm model is also 2 cm longer than a 152 × 188 cm model. Ask the supplier to confirm the proposed fit.
What makes EMMA Zero Gravity different from the other spring mattresses?
EMMA Zero Gravity combines an AirGrid gel grid, foam layers and AeroFlex pocket springs. Origin combines a latex comfort layer with pocket springs, while MR. LIVING uses memory foam and additional foam above pocket springs. These construction differences help narrow the shortlist; comfort preference and compatibility with your frame still need checking.
Will a thinner mattress make my bed lower?
On the same supporting surface, a thinner mattress generally lowers the nominal sleeping height. Replacing a 27 cm mattress with a 25 cm model would reduce that height by about 2 cm before accounting for actual dimensions and compression. Check the resulting bed height and visible headboard, as well as width and length.
Can I use these mattresses on an electrically adjustable bed frame?
Do not assume that every model is suitable. Ask the manufacturer to confirm compatibility with your specific adjustable base. IKEA lists a mattress base or non-adjustable slatted base for the VALEVÅG version compared here. NF004’s rearrangeable internal inserts do not, by themselves, establish suitability for an adjustable frame.
How much clearance should I leave between the mattress and bed frame?
There is no single clearance figure established for all six models in this comparison. Ask the supplier about the selected mattress’s dimensional tolerance and the frame’s usable opening. A dimensional tolerance or warranty exclusion is not an installation-gap requirement. Ask the supplier to confirm the appropriate fit for your frame rather than using the tolerance as a clearance rule.
