First memory foam pillows my wife and I have ever used. We absolutely love them. Being able to remove or add layers is genius since I like a thinner pillow and she prefers more layers. Very easy and quick to customize your own preference. Purchased along with the Polysleep mattress which has changed our life. No more aches or pains. Took a couple of nights to adjust but the results since have been great. Also the first memory foam mattress we’ve owned. Delivery was extremely fast and setup was a breeze.
