Primepatio Primepatio outdoor chair seat cushions set of 2 (7cm thick, 45 x 45cm) – grey waterproof rattan-style patio pads with ties

The essentials first: what these cushions are for

Primepatio’s outdoor chair seat cushions (sold as a set of 2) are made to give patio dining or garden chairs a softer, more supportive seat without making things complicated. With 7cm thickness and a foam core designed to spring back after sitting, they’re aiming at everyday comfort for long lunches outside.

They also focus on practicality: the covers are described as waterproof and UV treated, and the cushions come with ties to help keep them in place. That combination—comfort plus a more secure fit—is where these stand out on paper, because outdoor cushions can be a bit of a nightmare if they slide or soak up water.

The real test, of course, is whether your specific chair design suits 45 x 45cm cushions and whether you’re happy with a tie-based hold rather than a fitted cover system.

Key features that matter when you’re using them outdoors

On the comfort side, these cushions use a thick foam build described as high-density / memory-foam style with an easy recovery feature. In plain terms, it’s designed to retain its shape rather than going flat after repeated use.

For the outdoors angle, they’re described as UV and waterproof treated. The brand claims they won’t fade under direct sunlight for over 500 hours, and that the fabric helps resist stains and keep rain out—though the advice is still to bring them indoors when it rains or when you’re not using them if you want them to last longer and stay looking good.

They’re also held down by adjustable ties. There are two ties on each side, so you can position the pad where you want it, which should make a visible difference if your chair surface is slightly smooth or curved.

And yes, there’s a small aesthetic plus: the stitched edges are described as a double-layered finish for added durability and looks.

What you’ll notice day to day (the good and the limitations)

The comfort side is the big draw. A 7cm seat pad tends to feel like more than just a thin topper, especially if your chair has a firmer seat or you spend any real time sitting outdoors.

The tied design is also genuinely useful in day-to-day use. When cushions are unsecured, you end up adjusting them every time someone sits down. With ties, you should get a steadier look.

That said, there are a couple of limitations to keep in mind. First, these cushions are meant for outdoor use, but they still recommend bringing them indoors when it rains—so they’re not a “leave outside all winter no matter what” type of setup. Second, because they’re a 45 x 45cm square, they’ll only make sense if your chair seat area matches that size and shape closely.

How it fits into your patio setup (and who it suits)

It makes sense if you’re putting together a patio dining corner and want your chairs to look finished and feel comfortable—without having to swap out the chairs themselves. The grey colour is fairly easy to coordinate with common outdoor schemes, and the idea is to refresh existing furniture with a coordinated, more comfortable seat.

It also suits anyone who likes a straightforward maintenance routine: wipe down as needed, use the ties to keep things aligned, and follow the “bring indoors when wet” advice when weather turns.

If you want cushions that can be permanently left outdoors through frequent rain, or you need a very tailored fit for a non-standard chair shape, you may find this approach a bit restrictive.

Worth checking before you buy

Before committing, it’s worth checking three things:

• Seat size match: these are 45 x 45cm cushions, so measure or compare your chair seat before ordering.
• Weather expectations: they’re described as waterproof/UV treated, but the guidance is still to bring them indoors when it rains or when not in use. If you can’t do that, consider whether this matches your lifestyle.
• Fixing method: ties help keep the cushions stable, but you’ll be using them—so make sure the chair design gives you something sensible to tie onto.

Mini FAQ: quick answers to common buying questions

Are these cushions designed for outdoor use? Yes. They’re described as intended for patio or deck use, with UV and waterproof treatment.

Do they come with anything to stop them sliding? They include ties, with two adjustable ties on each side to help position the cushion and keep it stable.

Will they fade in strong sun? The description claims they won’t fade under direct sunlight for over 500 hours, but it still helps to follow good care and storage habits.

Do I need to bring them inside when it rains? The recommendation is to bring them indoors when it rains or when not in use, to help preserve lifespan and keep them looking good.

Final verdict

Should you buy it?

This is a solid purchase if you want thick (7cm) outdoor chair seat cushions with ties, and your chair seats suit 45 x 45cm pads. The waterproof/UV treatment and shape-recovery foam sound like a practical combo for regular patio dining, especially if you’re happy to bring cushions indoors when the weather gets messy.

You may want to skip it if your chair seat doesn’t line up with a square 45 x 45cm cushion, or if you’re looking for a set that can be left out continuously regardless of rain. In those cases, tie-based placement and the “bring indoors” guidance could end up feeling like friction rather than convenience.
