ComfyBump vs Sleepybelly: A Clear Comparison for Expecting Mums

If you're navigating your second or third trimester and looking for the right pregnancy support pillow, you've likely come across both Sleepybelly and ComfyBump. Both brands aim to improve comfort, reduce discomfort and support safe side sleeping, but each takes a slightly different approach. Here's a detailed look at how they compare, to help you decide which one suits you best.

1. Design & Adjustability

Sleepybelly:

Uses a three-piece modular design: one long support pillow + two side wedges
It's described as "adjustable" via configurable layout (though the support firmness is fixed)
Designed to encourage side sleeping and prevent back sleeping, which is recommended during later pregnancy

ComfyBump:

Features a modular three-piece structure as well but with adjustable firmness, meaning you can customize how firm or soft the support is as your body changes throughout your pregnancy
Specifically designed to encourage side sleeping, provide strong back support and prevent back sleeping, which is recommended during later pregnancy

Advantage: If you want greater control over how firm your pillow feels, ComfyBump offers stronger customization.

2. Comfort & Support

Sleepybelly:

Aims to support belly, back and hips through its wedge and back piece design

ComfyBump:

Provides full body support (bump, hips, back) with a strong emphasis on adjusting firmness so each expectant mum can find her optimal setting
Especially helpful if you experience varying discomfort (e.g., hip or pelvic pain) as your pregnancy progresses and the optimal firmness or support need to shift

Advantage: For changing comfort needs over time (especially if you have hip and back fatigue), ComfyBump may deliver more consistent support.

3. Materials & Quality

Sleepybelly:

Uses natural latex inner fill ("activated latex cushion") and a removable, breathable "air layer" cover made from a bamboo/polyester blend with anti-bacterial treatment. Not adjustable
Machine washable covers
Natural latex filling is quite heavy and can be hard to move around

ComfyBump:

Premium microbeads that you can adjust to suit your comfort level
Also uses premium, pregnancy safe materials, designed with OEKO-TEX® certification to assure non-toxic safety, easy care covers and durability through pregnancy and postpartum
Machine washable covers
Extremely light and easy to move around and change positions

Advantage: Both brands are high quality; the difference depends on whether you prioritise a fixed premium material, although quite heavy (Sleepybelly) or adjustable comfort plus safety certification plus lightweight (ComfyBump).

4. Temperature & Bed Footprint

Sleepybelly:

Highlights a compact bed footprint: "designed to be small and supportive so both you and your partner can enjoy a deeper, more restful sleep"
Breathable cover materials help with temperature but natural latex can still retain heat for some users

ComfyBump:

Designed with breathable, cooling materials and sheet cover in mind and a lower bulk form so it doesn't overwhelm the bed or make your sleep partner migrate
The adjustable firmness helps avoid the "too soft or too firm" trap, which can contribute to temperature discomfort

Advantage: If you share your bed and want minimal disturbance plus cooler sleep, ComfyBump may edge ahead.

5. Postpartum & Longevity

Sleepybelly:

Converts to a breastfeeding pillow or support pillow after pregnancy thanks to its modular 3 piece design
Suitable from early pregnancy through to full term

ComfyBump:

Also designed for pregnancy and beyond, from bump to baby, including breastfeeding support, lounge time, and general comfort postpartum
The adjustable firmness and modular design support longer use across stages and changing body needs

Advantage: ComfyBump offers strong postpartum value; if you're looking for one support pillow to carry you from pregnancy into motherhood, it's a very relevant choice.

6. Which Is Right for You?

Both brands aim to make pregnancy more comfortable, but how they do it is where the difference really shows.

Sleepybelly offers a fixed firmness pillow designed for side sleeping, which may suit those who prefer a set, structured feel.

ComfyBump, on the other hand, was designed with real mums in mind, offering fully adjustable firmness, breathable materials, and versatile support that adapts to your body as it changes. It's the kind of pillow that grows with you, from the early weeks right through to postpartum.

Bottom line: If you're after a one size fits all pillow, Sleepybelly might be enough. But if you want a pregnancy pillow that truly supports you at every stage—flexible, customisable, and designed for lasting comfort—the ComfyBump Pregnancy Pillow is the clear choice.
