FORTEM Office Chair Cushion (Memory Foam) XL – non-slip seat cushion with washable cover
Product description
If you spend long stretches sitting, a chair pad can be the difference between “fine” and “why does my seat feel hard today?”. The FORTEM Office Chair Cushion is built around memory foam with a supportive, ergonomic U-shaped hollow design, plus a non-slip base to help it stay where you put it.
That said, it’s not a magic fix for a badly adjusted chair. Over time, seat comfort still depends on posture and how your chair fits you—so this cushion works best as an add-on to improve feel rather than replace everything.
The essentials
This is an XL memory foam seat cushion for desks, gaming setups, and even travel by car. On paper, it’s designed to soften pressure while also giving you a bit of structure thanks to its U-shaped hollow channel. The moulding effect is the main comfort idea: memory foam aims to take on your shape and then return back after each session.
It also includes practical details that matter day to day: a non-slip rubber bottom so the cushion doesn’t creep about as you move, a washable cover you can remove, and a built-in handle for carrying between rooms or when you’re away.
What stands out in everyday use
The comfort goal here is fairly clear. Instead of a flat pad that can feel squishy or uneven, the U-shaped hollow design is meant to support you while helping reduce pressure build-up in the middle area. If you’ve ever shifted around in an office chair because the seat feels too firm, this is aimed at making that “seat pressure” problem more manageable.
You’ll also notice the non-slip base quickly. Many seat cushions slide or bunch up—this one is specifically set up to stay put, even when you’re changing position during work or gaming.
Where it makes sense (and where it may not)
It tends to be a sensible choice if you want a portable seat riser-style comfort boost for different environments. The product description points to office chairs, car seats, gaming chairs, and even bleachers, which fits the “use it in multiple places” buyer mindset.
However, it may be less ideal if you’re expecting it to transform your chair into something ergonomic on its own. A memory foam cushion can improve comfort, but it won’t correct lumbar support or fix an improperly set-up workstation.
Also, if you prefer a very firm seat feel, memory foam’s softness/slow response may not match your taste. That’s not a flaw, just something to consider before you commit.

Buying checklist before you choose
A few things are worth thinking through before buying any seat cushion like this.
First, think about your main problem: is it too much pressure on the seat, general firmness, or needing extra comfort during longer sitting sessions? If it’s pressure and hardness, a memory foam pad with a hollow channel is exactly the type of solution it’s positioned as.
Second, consider cleaning. The washable cover is a real plus if you’re using it regularly (office, home, car). Still, you’ll want to check that the cover design and unzipping method suits your routine.
Finally, check whether XL is the right size for your chair/seat area. Cushion placement matters—if it’s not well centred, you may not get the comfort benefits you’re expecting.
Mini FAQ
How does memory foam feel compared with a basic cushion?
Memory foam is designed to mould to your body, which can make it feel more pressure-relieving over time than a flatter foam pad. The trade-off is that it may feel softer than you expect if you normally like a firm seat.
Will it slide on smooth chair covers?
The non-slip rubber bottom is specifically included to keep the cushion securely in place, even when you move around.
Can I wash the cover?
Yes—according to the product description, the cover is machine-washable. You unzip it and then wash it.
Can I use it in different settings like car seats and gaming chairs?
The description says it’s designed for office chairs, car seats, gaming chairs, and bleachers, so it’s intended as a versatile comfort pad rather than a single-purpose cushion.
Is an XL cushion necessary?
“XL” can be a good fit if you want more coverage or a more stable seat area. If your chair seat is small or you prefer a minimal pad, you might want to consider whether XL is too large for how you sit.
Final verdict
It’s a solid pick if you’re after memory foam comfort that stays put, with an easy-to-clean washable cover and the practical option to carry it around. The U-shaped hollow design is particularly relevant if your seat feels too firm or pressure builds during longer sessions.
You may want to skip it if you’re looking for a cushion to fully replace ergonomic support, or if you strongly prefer a very firm, non-moulding seat feel. Worth considering if you want one cushion you can use across office, home, car journeys, and gaming—just make sure XL is the right size for your chair and how you plan to place it.
