Industry standard cutting tolerances Please fully unwrap your foam as soon as it is delivered, allow it to settle for 24 hours prior to checking tolerances. Report size related issues within 48 hours. Do not allow foam to remain wrapped for prolonged periods, as it can permanently shrink or compress below normal manufacturing tolerances. Shrinkage can sometimes be reversed by simply stretching the foam slightly. Foam is elastic in nature, its dimensions are not fixed as foam is a stretchy and playable medium. For all foam grades the following applies: Thickness:Thickness +/- 5 mm (Please note this can be more of an issue when cutting thickness less than 50 mm). Length & Width :1cm in every 120 cm. Please just contact us if you need any more information. Firmness & Density are often confused. They are not the same!Density is the weight of the foam given a specific volume, for example Reflex 40 grade is 40 kg per cubic metre. As a rule of thumb, the higher the density the better the quality. Firmness has no bearing on density, you can have a high density firm cushion or high density soft cushion or vice versa. The hardness of the foam is determined in Newtons, by rule of thumb 60 newton foam is soft, 135 newton is medium firm, 200 newton and over is firm. Dacron wrapped Foam:Please note Dacron has a maximum usable width of 100 cm. Not recommended for use on memory foam as it will compromise the memory properties of the memory foam. Dacron can be used in conjunction with memory foam if its being used for a back cushion where it’s inherent softness is the primary reason for its usage. Stockinette:Please note we can fit stockinette up to maximum 1.5 m in width and minimum 5 cm thickness. However, it’s a one size fits all stretchy medium, so on smaller size cuts the stockinette may not be a tight fit. If you pay for stockinette that cannot be fitted within this tolerance, we will send you the amount paid for. Stockinette being hand fitted may increase the thickness of foam at its fixing point, due to the foam being slit to accommodate tucking of the stockinette to produce a clean finish. Memory Foam:All measurements are approximate due to shrinkage and expansion caused by temperature. Please note memory foam orders above 180 cm x 200 cm will require to be joined, if this is the case please notify us asap how you would like it to be joined. Memory foam is only available in 1″ 2″ or 3″ thickness or metric equivalent. Order in multiples of these thicknesses will be laminated, where this is not possible due to the thickness chosen, we will cut to the nearest 1″. Coolteck & Tencel Covers:If ordering a product with a Coolteck or Tencel cover (especially a memory foam topper) as with any knitted fabric it relaxes with use. This is perfectly normal however it may give the impression that the product is incorrectly sized. This will resolve itself with one night usages. The initial tension in the fabric (until relaxed) can pull in soft visco-elastic memory foam by up to 5cm 50/50 Split Products:Customer ordering a 50/50 split dog bed should be aware that memory foam come in 1″ 2″ 3″ or metric equivalent thickness and should therefore order an overall thickness that reflect this. We reserve the right to amend orders to the nearest 1″ or 2.5cm, if we can’t tessellate the order exactly due to the sizes provided. Budget Foam:This grade of foam is unsuitable if you require exact sizes (see above tolerances), we cut this foam to the nearest inch or 2.5 cm however thickness can be variable within 2.5cm. This foam is made from off cuts left over from production, each item will be in one grade but may be discoloured and or joined. Various grades can be used to make up a single order, we cannot guarantee the grade of foam sent nor its suitability for any application. Discoloration:Foam is highly photo sensitive and may dis-colour due to light penetration. Foam Smell:Please note foam has a distinctive odour, this is completely normal and will disperse in time, given suitable ventilation. Some customers may also find themselves intolerant to the smell, no liability is accepted for any discomfort caused. Joined Foam:Due to the limitations of foam sheet sizes you must expect all order over 200 cm to be joined or supplied in component parts (Foam bond provided FOC) . We also routinely join foam with a pink Simalfa not toxic water based adhesive to minimize waste, the subsequent savings are passed to the customer with competitive pricing. Sheet size:Foam blocks vary in size. Please note if you require larger than standard sheet size, we will supply in constituent parts. The sheet size vary from grade to grade. Foam grade Substitution:We may on occasion substitute the grade chosen with a higher density or a grade of a different colour, when the firmness and density remain equal to the original customer choice.Need Foam Cut to Size?
