Serta Perfect Sleeper Comfy Sleep Pillow vs Allswell Side Sleeper Bed Pillow

The Serta is the safer buy for most people: it comes as a two-pack, has a strong 4.4 rating from nearly 2,000 owners, and its recycled microfiber build is easy to care for. The Allswell is the more targeted pick for side sleepers, with a 3.5-inch gusset for edge-to-edge neck support and a breathable HYGROCOTTON cover, but its 3.7 rating from far fewer owners is a caution. Neither is a premium pillow; the Serta wins on value and consistency, the Allswell on shape and cooling for side sleeping.

  • Choose the Serta Perfect Sleeper if you want two soft, hypoallergenic pillows for a guest room or a household, or you sleep on your back or stomach and prefer a flatter, washable microfiber pillow.
  • Choose the Allswell Side Sleeper if you sleep on your side and want a gusseted pillow that holds height at the edges, plus a cotton cover that breathes better than microfiber.

What reviewers say

Serta Perfect Sleeper Comfy Sleep Pillow

  • 4.4 / 51,944 ratings

Allswell Side Sleeper Bed Pillow

  • 3.7 / 5151 ratings

Questions and answers

Which is better for side sleepers?
The Allswell. Its 3.5-inch gusset holds height at the edges so your neck stays supported, and the medium-to-firm fill suits side sleeping. The Serta is softer and flatter, which suits back and stomach sleepers better.
Which lasts longer?
Both are polyester-filled and machine washable, so lifespan depends on care. The Serta's larger owner base reports fewer complaints, while the Allswell's cluster fill can clump if it is not tumble dried fully. Use a protector on either to extend life.
Is the Allswell worth stepping up to over the Serta?
Only if you sleep on your side or want a cooler cotton cover. Otherwise the Serta gives you two pillows, a higher owner rating and hypoallergenic fill for general use.
Does the Serta come in King?
No. The Serta two-pack is Standard/Queen only, at 20 by 28 inches. The Allswell comes in both Standard/Queen and King.
Which sleeps cooler?
The Allswell. Its HYGROCOTTON cotton percale cover is temperature-regulating and breathes better than the Serta's microfiber cover, which tends to trap warmth.
Are either good for allergies?
The Serta is the better fit: its fill is hypoallergenic and the tight microfiber weave acts as an allergen barrier. Both are machine washable, which helps keep dust mites down.
