If you dislike a bouncy surface, start by comparing foam mattresses. If you prefer a spring-supported response when turning over, put spring mattresses on your shortlist. Then check the actual construction: foam can be firm, spring mattresses can have cushioned tops, and both categories contain very different products.
The better choice is the one that suits your preferred feel, how you share the bed and the frame you intend to use. Here is how to make that comparison without treating the material name as a promise of comfort.
What is inside a foam mattress?
An all-foam mattress uses foam for its support core rather than metal coils. The foam type matters. Standard polyurethane foam, memory foam and rebond foam are different constructions; the word “foam” alone does not identify which one you are buying.
Memory foam is known for contouring around the body and absorbing movement. Other foam designs can recover differently and feel much firmer. If you want a slow, body-hugging sensation, ask whether the mattress actually contains memory foam and where it sits in the layer arrangement.
What is inside a spring mattress?
A spring mattress uses metal coils for its support system, usually with cushioning above them. Foam in the comfort layer does not make it an all-foam mattress.
Two common spring constructions are Bonnell springs, which are interconnected, and pocket springs, which are individually wrapped and work more independently. Check which system the product uses rather than comparing every spring mattress as though it were the same.
A hybrid combines a spring support system with substantial comfort layers, often including foam or latex. If you see that label, look for a layer description so you know what is being combined.
Foam vs spring mattress: the practical differences
| What matters to you | Foam mattress | Spring mattress |
|---|---|---|
| Surface feel | Varies with foam type and layers; memory foam can contour closely. | Coils add a spring-supported response; the top layers change how it feels. |
| Partner movement | Foam can dampen movement, especially memory foam. | Check pocket versus interconnected springs and the comfort layers. |
| Warmth | Some foam designs retain more warmth; construction matters. | Space around coils allows airflow, but the upper layers still matter. |
| Firmness | Available in different firmness levels. | Available in different firmness levels. |
| Bed-frame fit | Confirm thickness, dimensions and required foundation. | Confirm thickness, dimensions and required foundation. |
Choose around the problem you want to solve
If a partner's movement bothers you
Shortlist mattresses with a clear explanation of movement control. Memory foam is worth considering; so are pocket-spring designs whose comfort layers help dampen movement. A product demonstration can be useful, but it should not be treated as proof that you will feel no movement at all.
When asking about a model, describe what wakes you: someone turning over, getting out of bed or sitting on the edge. That gives the seller a more useful question than simply asking whether foam or springs are better for couples.
If you dislike sinking into the surface
Ask how quickly the upper layers respond when you change position. A responsive spring design may suit your preference, but a firmer foam mattress could also be relevant. Avoid ruling out every foam model because you once disliked a soft memory-foam bed.
Likewise, a thick foam comfort layer over springs may feel quite different from a spring mattress with a thinner, firmer top. Compare the complete mattress rather than the core in isolation.
If you often feel warm at night
Spring construction can provide space for airflow, while closely contouring foam may feel warmer. That does not make every spring model cooler than every foam model. Ask what the cover, comfort layers and ventilation features are designed to do.
For a Singapore bedroom, describe whether you usually sleep with a fan or air-conditioning and what bedding you use. A cool-touch fabric claim alone does not tell you how the full mattress will feel throughout your night.
If you are buying mainly on budget
Compare the same mattress size and the full delivered price. Check whether the listing is for a mattress alone or includes a frame. Ask which specifications explain the difference in price, rather than assuming that springs or greater thickness automatically mean a better purchase.
Six mattresses to compare by core and comfort layer
Each of these six mattresses has a spring support core. The foam or latex above it changes the surface cushioning, while the spring system remains part of the construction. Compare both layers when deciding what to shortlist.
| Mattress | Listed thickness | Spring core | Main comfort layer |
|---|---|---|---|
| Diamond Plus | 10 inches | Tempered Bonnell springs | High-density polyurethane foam with Euro top quilting |
| Snoova Prestige | 33 cm; labelled 13 inches | 7-zone individual pocket springs | 5 cm natural latex pillow top |
| Snoova Premiere | 33 cm; labelled 13 inches | 7-zone individual pocket springs | 4 cm gel-infused memory foam plus 2 cm HD foam |
| Snoova Deluxe | 30 cm; labelled 12 inches | 7-zone individual pocket springs | 3 cm HD foam pillow top |
| Snoova Ergo | 25 cm; labelled 10 inches | 7-zone individual pocket springs | 4 cm HD foam |
| Snoova Comfort | 25 cm; labelled 10 inches | 5-zone individual pocket springs | 3 cm HD foam with a tight top |
These measurements follow the current listings. Confirm the supplied thickness for your size and bed frame. Zone counts describe the support arrangement; a larger number alone does not establish which mattress will feel better to you.
Diamond Plus: Bonnell springs with foam cushioning
The Diamond Plus 10-Inch Euro Top Mattress combines tempered Bonnell springs with high-density polyurethane foam. Its listing describes a medium-firm feel rated 7/10. Use that as the seller's description rather than a universal scale, and compare the connected spring system with pocket-spring options if partner movement is a priority.
Snoova Prestige: natural latex over pocket springs
The Snoova Prestige Mattress has a listed 5 cm natural latex pillow top over individual pocket springs. It is an option to investigate if you are interested in latex cushioning rather than a memory-foam comfort layer. At 33 cm overall, it also needs a careful check against your frame's permitted mattress height.
Snoova Premiere: memory-foam comfort with a spring core
The Snoova Premiere 13-Inch Mattress is a useful example of why “contains memory foam” does not mean “all-foam”. Its layer description includes 4 cm of gel-infused memory foam, 2 cm of HD foam and 7-zone pocket springs. Compare this construction if you want memory foam in the comfort layers while retaining spring support.
Snoova Deluxe: an HD foam pillow top
The Snoova Deluxe 12-Inch Mattress uses a 3 cm HD foam pillow top over a pocket-spring core. The listing describes the surface as medium-soft. It gives you another comfort-layer construction to compare with Prestige's latex and Premiere's memory foam; the pillow-top label alone cannot tell you how similar they will feel.
Snoova Ergo: a 25 cm pocket-spring option
The Snoova Ergo Series 10-Inch Mattress combines a 4 cm HD foam layer with 7-zone individual pocket springs. Its listed height is lower than the three pillow-top models above. Ask for a firmness description and check the full layer arrangement; a thicker foam layer does not, by itself, mean a softer mattress.
Snoova Comfort: a firm tight-top design
The Snoova Comfort 10-Inch Tight Top Mattress is described as firm, with 3 cm HD foam over 5-zone pocket springs. It is worth comparing with Ergo if you are choosing between these two 25 cm models. Ask how the overall feel differs rather than deciding from the foam thickness or zone count alone.
Check your frame before deciding on either type
A suitable mattress construction still needs a compatible foundation and the correct dimensions. Before ordering, confirm:
- Actual mattress dimensions: compare length and width with the frame's usable internal space, especially for enclosed daybeds.
- Permitted thickness: check clearance beneath a pull-out bed and any limits specified for the frame.
- Required support: ask whether the mattress needs a solid platform or a particular slat arrangement, including any maximum gap.
- Finished bed height: consider the support surface plus the mattress, particularly if you want to keep a familiar sitting height.

Questions to settle before buying online
Ask for the support-core type, comfort-layer materials, thickness and firmness description. For a spring model, confirm the spring construction; for a foam model, confirm the foam type. Check warranty coverage and the return conditions before removing any packaging. A warranty period is not a promise of how long the mattress will feel right for you.
Send us your current frame dimensions, what you like or dislike about your existing mattress and whether you share the bed. Those details make it easier to narrow down a suitable option than a material label alone.
