Pros and cons
Pros
- Two stated comfort sides give buyers an option to change the feel without replacing the topper.
- A removable machine-washable cover is practical for routine care. The foam itself should not be washed.
- Its stated double dimensions and adjustable straps suit buyers seeking a topper to fit a 135x190cm bed.
Cons
- The topper is explicitly listed as not water resistant, so it does not replace a waterproof protector.
- The foam is not washable, leaving cleaning dependent on the removable cover.

What to know before buying

- The listing states a 100-night trial and a 10-year warranty. Review the selected listing for the terms and eligibility before purchase. The claimed OEKO-TEX and CertiPUR-US certifications are listing claims.
