Great fluffy ones
Color: White, Size: King(2Pack)
I originally order this pillows to use as Shams for an oversize king comforter but they came out to small for that, but after seen the qualitu i kept them for my daily use ones.
The size is perfect, and the quality feels much higher than the price suggests. It's soft yet supportive, holds its shape well, and adds a real touch of comfort to the bed. For the price, it’s a fantastic deal. The pillow look big and they are super fuffly.
Highly recommend if you're looking for great value without sacrificing quality!

Fantastic pillow
Color: White, Size: King(2Pack)
Super comfortable for a bit of a firm pillow it is king size and lightweight, it gets pretty warm pretty quick, I stack both pillows on top of each other in the same pillow case for extreme support but that's just me.

King size great pillows!!!!!
Color: White, Size: King(2Pack)
I ordered this 2-pack of king-size pillows to upgrade my bed, and I’m so glad I did. The size is perfect for a king bed and instantly made everything look more full and put together.
When they arrived, the pillows fluffed up nicely and felt soft yet supportive. They’re not too flat and not overly firm, which makes them really comfortable whether you’re sleeping on your back or side.
I’ve been using these for a bit now and they’ve held their shape well through the night. They provide good neck and head support without feeling stiff, and they don’t go flat by morning.
What I like most is how versatile they are — great for sleeping but also perfect for propping up in bed while reading or watching TV. For a two-pack, the quality is honestly impressive.
Overall, these are a great value and exactly what I was looking for. If you want comfortable, well-filled king-size pillows that look and feel great, I would definitely recommend this set.
