What to Look For When Buying a Fiber Bed

If you want to take your bed to the next level in comfort, look no further than a fiber bed. These heavenly soft bed toppers are filled with synthetic materials, making them 100% hypoallergenic and a more affordable alternative to down featherbeds. Dreaming of the perfect fiber bed? This guide will help you demystify the different components.




Fiber beds can be filled with various synthetic materials, including blends of different types. These are a few of the types you might come across.

Synthetic Cluster Fiber

This synthetic down alternative consists of clusters of synthetic fill, resulting in a puffy layer that maintains its loft.

Micro Fiber

This lightweight material has down-like softness. It creates a satisfyingly thick surface that is plump and airy.  

Synthetic Polyester Fill

This type of fill is made up of polyester threads; fill using thinner strands of thread will be dense and warm, while fill using thicker strands of thread will be lofty and durable.

Gel Fiber Fill

Gel fiber is made to feel just like down. It’s 100 times finer than most other polyester fibers, making it delightfully plush and fluffy.



Support Type

The level of support that you’ll want from your fiber bed will come down largely to personal preference. Be sure to test a few out before picking the right support type for you.

Less Supportive

A fluffy fiber bed will provide you with the ultimate in comfort. If the idea of floating on a cloud sounds good to you, this might be the right option.

More Supportive

If you prefer a more supportive surface or are prone to back support issues, look into more supportive fiber bed options.




There’s nothing more disappointing then when all of the fluffy filling piles into one corner of a bed topping, leaving the rest of the material totally flat. That’s why the construction type matters: it will ensure that the fill is evenly distributed for optimal levels of bliss.

Baffle Box

Baffle box construction means that strips of fabric are sewn between the top cover and bottom cover of the fiber bed, diving the inside of the bed into several “compartments” in a checkerboard pattern. Baffle box construction is great for keeping the heat in, perfect for a more heavyweight fiber bed.

Box Stitch

Box stitch construction is similar to baffle box, but instead of using strips of material to create compartments, the compartments are created by directly stitching together the top and bottom layers of the fiber bed. Box stitch construction usually gives a fluffier, puffier appearance, and is great for lighter weight fiber beds.




Since your fiber bed lies directly on top of your mattress, a proper fit is important. Fiber beds are soft and malleable, so it’s not the end of the world if it’s a little big or small for your mattress—having said that, it doesn’t hurt to take proper measurements ahead of time to ensure the closest fit.

Twin (39"x75"x2")

This smallest option will fit single or twin beds.

Twin XL (39"x80"x2")

If you have an extra long twin bed (often found in dorm rooms), this is likely your best bet.

Full (54"x75"x2")

A double bed calls for a full sized fiber bed.

Queen (60"x80"2”)

A queen size fiber bed should fit most queen-sized beds.

King (78”x80”x2")

If you’ve got a great big king bed, a king fiber bed is what you’ll need.

Cali King (72"x84"x2")

The longest of all the options, a cali king fiber bed means regal levels of comfort.
