## At a glance

- Flip the mattress to choose between a shaped-cut soft side and a flat-cut medium-soft side.
- The listing describes matching fabric on both sides, so switching firmness does not require removing the cover.
- The zip-off cover is described as removable and machine washable.
- Supplied compressed and rolled. The listing advises allowing 48–72 hours to expand before sleeping on it.

## Pros

- Two stated comfort choices in one mattress, without needing to remove its cover to flip it.
- The 15cm profile and listed 7.9kg weight may suit buyers who prefer a slimmer, lighter mattress.
- A removable cover that the listing says can be machine washed.

## Cons

- At 15cm thick, it offers a slimmer profile than many mattresses, which may not suit buyers looking for a deeper mattress.

## Before you buy

- The listing is inconsistent about package contents: its title describes a mattress in a box and the details list a manual and unpacker, while a removable cover is described in the feature text. Confirm whether the cover and unpacking tool are included in the selected listing. The 48–72 hour expansion period is also specified.

## In the box

- Manual (Included)
- Unpacker (Included)
- Removable cover (Check selected pack): Described in the feature text but not specified in the included-components list. Check the selected listing.

## A good fit for

- Small-double bed owners seeking a 120 x 190cm foam mattress with soft and medium-soft options.
- Buyers who want a slimmer mattress and a removable, washable cover.

## Less suited to

- Shoppers seeking a thick mattress or a firmer feel than the listed soft and medium-soft choices.
- Anyone who needs a confirmed package inventory before ordering without checking the selected listing.

## Customer feedback

Customer feedback praises perceived quality and value, while experiences with firmness and comfort are mixed. Some say the mattress feels less soft than expected, and comments include both improved and worse sleep. Some customers also report feeling springs at the side. That concern is worth weighing against the listing's one-layer high-density foam construction, which does not explain the reported spring sensation. The positive overall rating is accompanied by a meaningful minority of low ratings, so individual comfort may vary.
- Positive themes: Customers describe the mattress as good quality and good value.
- Negative themes: Some customers report feeling springs at the side of the mattress.
- Mixed feedback: Firmness feedback varies, including reports that it is not as soft as expected.
- Mixed feedback: Comfort reports differ, with some describing better sleep and others worse sleep.

## Frequently asked questions

### What are the two firmness options?
The listing describes a shaped-cut soft side and a flat-cut medium-soft side. Flip the mattress to switch between them.
### How long should it expand before use?
The listing advises waiting 48–72 hours after unwrapping for the compressed mattress to fully expand.
### Can the cover be washed?
The feature text describes a removable zip cover for washing, and the care details say machine wash. Package contents are inconsistent, so confirm the selected listing includes the cover.
### What comes with the mattress?
The listed included components are a manual and unpacker. The title and feature text also refer to a mattress in a box and removable cover, but the package information does not clearly corroborate all of these details.
