Is the Vibe Smart Edge good for side sleepers?

Yes. The contoured edge fills the gap under the neck and keeps the head level, which is what side sleepers need. Stomach sleepers may find it too tall and firm.

Does the gel layer really keep it cool?

The gel surface feels cooler than plain memory foam when you lie down. Most owners say the effect fades after a few hours, so it is not a substitute for a cooling mattress or a cool room.

Standard or Queen: which size should I get?

Standard fits most standard pillowcases and suits smaller beds. Queen fills a queen or king bed better and gives more room to shift position, but check your case size first.

Can I wash the cover?

Check the label on your version. Many shaped foam pillows have a cover that zips off for washing, but some do not, and the foam core itself should only be spot cleaned.

How does it compare with a shredded-foam pillow?

Shredded foam lets you add or remove fill to change the height. The Vibe is a fixed-shape foam pillow, so it offers more support but no loft adjustment.

Is it worth it over a basic memory foam pillow?

You pay more for the gel layer and the shaped edge. If you overheat or wake with neck pain, those features can justify it; if you sleep fine on flat foam, a basic pillow does the same job.
