Questions and answers

Which is better for side sleepers?
The Sertapedic Won't Go Flat. Its firm foam core keeps the neck supported, while the Perfect Sleeper is softer and can compress under the head.
Which lasts longer?
The Sertapedic is built not to go flat and carries a 3-year warranty. The Perfect Sleeper's soft fiber loft tends to flatten sooner, though washing helps refresh it.
Can I wash the Sertapedic pillow?
No. It is spot clean only. The Perfect Sleeper is machine washable, which makes it easier to keep fresh.
Is the Perfect Sleeper good for back sleepers?
It suits back sleepers who like a soft pillow. If you want firmer neck support, the Sertapedic is the better pick.
Are both hypoallergenic?
Yes. Both use hypoallergenic polyester fill, and the Perfect Sleeper's tight-weave cover adds an allergen barrier.
Is the Sertapedic worth stepping up to over the Perfect Sleeper?
If you need firm, shape-holding support and a warranty, yes. If you want a washable, plush pillow in a two-pack, the Perfect Sleeper fits better.
