Bedsure Pillow Top King Mattress Topper - 800G Plush Waterproof Fit

In this review of the Bedsure pillow top king mattress topper the bottom line is simple: it is best for sleepers who want an immediate boost in softness and reliable mattress protection. Filled with 800g of Blendtek+ fiber, the topper delivers a plush, cloudlike surface while a TPU waterproof layer guards the mattress against spills and accidents. Reviewers consistently praise the comfort and washability, and the 21-in deep pocket with elastic keeps it in place on deeper mattresses, making it an easy upgrade for home or hotel beds.

Key Features

• 800g Blendtek+ fill: Provides a generous pillow top feel that balances softness with light support for improved sleep comfort.
• TPU waterproof layer: Protects the mattress from spills and accidents while remaining quiet and unobtrusive under bedding.
• Five-layer breathable design: Mesh fabric around the edges promotes airflow so sleepers stay cooler through the night.
• 21-in deep pocket: Stretchy elastic bands secure the topper to mattresses up to 21 in deep, preventing slipping or bunching.
• Quilted box construction: Keeps the 800g filling evenly distributed so the plush surface stays consistent without shifting.
• Machine washable: Easy care means the topper can be washed and dried for regular maintenance and long-term hygiene.

Who It's For

This topper is ideal for side and back sleepers who want a softer sleeping surface without replacing their mattress, and for anyone seeking a waterproof layer to protect a mattress investment. Hospitality settings and households with occasional spills will also appreciate the TPU barrier and easy washability.

It may be less suitable for sleepers who need firm therapeutic support from a topper or those who prefer a very thin, minimalist mattress protector. Also, if you need extreme temperature regulation in very hot climates, a thinner cooling pad may perform better.

Pros & Cons

Cons

• Thickness is mixed in reviews-some may find it thicker or plusher than expected.
• Those needing firm orthopedic support may not find enough firmness from a plush 800g fill.
