Our take on the Mainstays Extra Firm Back & Side Sleeper Pillow

This is a standard/queen polyester pillow built for people who want a stiff, high-loft surface under the head and neck. The dense microfiber fill and 8-inch thickness give side and back sleepers more support than a soft down-alternative pillow, and the cover is machine washable and hypoallergenic. It sits at the firm end of the budget pillow market, where most rivals are medium or soft; reviewers who want that stiffness tend to like it, while stomach sleepers and fans of plush pillows often find it too hard and too tall.

Questions and answers

Is this pillow good for side sleepers?
Yes, it is designed for side and back sleepers. The extra-firm fill and 8-inch loft keep the head and neck supported, though it may be too tall for smaller frames.
Is it too firm for stomach sleepers?
Most stomach sleepers should look elsewhere. The extra-firm, high-loft build pushes the head up, which can strain the neck for stomach sleeping.
Can I machine wash it?
The polyester cover is machine washable. Check the care label for the fill, and dry it thoroughly to prevent clumping.
Does it come in King size?
This listing is standard/queen only. Check the Mainstays line for other sizes if you need a king.
Will it flatten over time?
Some owners report the microfiber fill clumping or losing loft after months of use. Fluffing it regularly helps it keep its shape.
Is it hypoallergenic?
Yes, the polyester microfiber fill is listed as hypoallergenic and free of common allergens.
