The 12 x 12 Ultima Pergola from Forest creates a beautiful focal point for your garden Ideal for training climbing plants across the top of the structure, you can create a stunning, scented, floral walkway bursting with colour, or perhaps a little shady spot so you can relax and dine al fresco underneath. Wisteria is always a popular choice, but we are certain you will love how your pergola looks when adorned with your favourite climber! 12 x 12 feet of space (3.6m x 3.6m) underneath gives you a lot of room, however we know not everyone has a garden that can fit such a substantial structure. That is why a 9 x 9 version (2.7m x 2.7m) is available for those who love the look of the Ultima but don’t have room in their garden for this size. Either way, there’s plenty of space underneath the Ultima Pergola, meaning you have lots of room for garden furniture. Get yourself an outdoor table and chairs or perhaps a picnic bench for the ultimate outdoor dining experience, or why not instead go for some rattan furniture or a weatherproof sofa for a simple chill out spot? However you see yourself relaxing under your new pergola, it’s certain to improve your enjoyment of the outdoors.

Plus, when painted in a colour of your choice, you can really ensure your Ultima Pergola steals the show. We have seen loads of examples of how fantastic it can look with a splash of colour to complement the rest of a customer’s garden. Many manufacturers recommend Protek Paint for the unbeatable protection it provides your timber and the wide range of colours to choose from – get the best from your Pergola by picking one of their 60+ gorgeous shades!


The timber is pressure treated, giving an excellent lifespan and unbeatable protection against rot, fungal decay and weathering. The timber is smooth-planed for a stunning and almost splinter-free finish. This is all backed up by a 15-year anti-rot guarantee. The FSC certified timber used is all sustainably sourced and of the highest quality, ensuring a durable build. The pergola posts are sturdily made and can be sunk into the ground; otherwise, any good bolt-in shoe for the legs will allow you to fix your pergola to a range of surfaces. Delivered flat packed with all fixtures needed, and easy-to-follow instructions.
