### ⭐⭐⭐⭐⭐ Softness and ease of fitting
*by M***E on 2 September 2025*

Ordered this as new bed is arriving soon have put it on existing bed and love the feel and comfort it offers. It has sturdy elastic on each of the 4 corners for a secure fit is lovely and warm and good value for the price.

### ⭐⭐⭐⭐⭐ Fab topper , super soft and great value !! Its lovely
*by V***X on 8 December 2025*

This is fab so comfy and revived our mattress !!

### ⭐⭐⭐⭐ Comfy and well made but not as thick as advertised
*by M***. on 20 December 2024*

Pros Well made and arrived in pristine condition (as in no broken straps, no tears and no dirty marks)- tick. Fits King Size as expected - tick. Adds softness, which is what I wanted - tick. Was a reasonable price - tick. Delivered promptly - tick. Cons - only 1 and this could be disappointing for people Not 10cm thick (that is the size I ordered) - got the measuring tape out to check! About 6cm in reality. The photo makes the item look really thick and what I got just isn't the same, so a bit of false advertising, tsk, tsk. If they advertised it as 6cm or 7cm then this would be a 5 star review. Can't be bothered to return it and quibble. Word to the wise My standard King Size flat sheet doesn't fit now this topper is on the bed, so will try a Super King size instead. Not anything to do with the item, just something to consider if you buy one and want your sheet to properly tuck under the mattress.
