King Mattress Pad Extra Thick Cotton Topper - Plush 500GSM Support

Our review of this king mattress pad finds it is best suited for sleepers who want a plush, breathable layer without replacing a mattress. The single biggest reason to buy is the noticeably thicker 500GSM down alternative filling that creates a soft, cushioning surface while the OEKO-TEX certified cotton top stays quiet and breathable through the night. For anyone with a tall mattress or who wants an easy-to-care-for topper that stays put, this pad delivers sensible comfort rather than a dramatic firmness change.

Key Features

• 500GSM Thick Filling: The premium 7D hollow microfiber filling provides a luxuriant, indented cushioning that softens pressure points without excessive sink.
• 100% Cotton Top: The OEKO-TEX certified cotton top feels breathable and hypoallergenic, helping regulate temperature for a cooler sleep surface.
• Deep Pocket Fit: The 18 in skirt with stretch to 22 in ensures the pad fits tall mattresses and stays secure under movement.
• Quilted Construction: Diamond quilting with edge piping keeps the filling evenly distributed so the plush loft remains consistent night after night.
• Noiseless Design: Materials are chosen to avoid rustling, so the pad stays quiet even when turning in bed.
• Easy Care: Machine washable construction and sturdy stitching make the pad durable and simple to launder on a gentle cycle.

Who It's For

The pad is ideal for couples or solo sleepers who want a thicker, cloud-like surface over an existing mattress without altering the underlying support. It is particularly good for people with tall mattresses who need a cover that fits up to 22 in and for those who prefer natural cotton against their skin.

It is less suitable for someone seeking a firmer therapeutic topper to change mattress support dramatically, or for those who need an ultra-thin protector; this product adds plush cushioning rather than firm orthopedic correction.
