Replacement Sofa Bed Mattresses

Product Description

Hand finished replacement sofa bed mattresses of the highest quality supplied by the UK's leading sofa bed specialist. Our mattresses are made to our specification by craftsmen in the UK - we supply 7 different grades of mattress suitable for use on the most popular sofa bed mechanisms - each one can be viewed in the image gallery above.

Our mattresses fully comply with current flammability regulation (BS 7177 / BS EN 597-1/2) and have the appropriate flammability label attached to the product. Not only is this essential if the mattress is for your own use but also if the mattress is to be used in a letting property as current law requires bedding to meet fire regulations and have the appropriate label in place.

When choosing a new mattress, the general rule is to replace 'like with like sizes', for example if your original mattresses measures 130 x 180 x 11cm, choose one of our mattresses of the same or very similar dimensions.

Deluxe Sprung Sofa Bed Mattress

Our high quality fully sprung sofa bed mattress finished in a luxury damask fabric, is designed to replace the unit found on most better quality webbed and slatted metal action sofa bed mechanisms. Using our unique flex-comfort open coil spring unit, the mattress easily folds within the mechanism and offers excellent levels of support when in the bed position. The flex-comfort spring unit has a spring count of 288 (large double size), resulting in a mattress which offers a medium level of support. Layers of natural padding isolate the springs with further layers of reflex foam used to cushion the user.

This mattress benefits from 2 sided finishing so both sides of the mattress can be used to even out mattress wear. Available in a range of sizes from 76cm wide chair bed to 144cm wide sofa bed.

When converting the mechanism from bed to sofa, this type of mattress folds over once, the carriage then drops to within the sofa and approx 10cm of mattress folds upwards and behind the back cushion panel. This type of mechanism is referred to as a "2 fold" sofa bed mechanism.

Important Measuring Information

Before ordering, please measure your existing mattress to ensure you select the correct size for your frame, also realise that 2 fold (thicker) mattresses will not fit into a 3 fold metal action ! If unsure, please telephone us for our advice before ordering. Please note that due to manufacturing tolerances, allowance should be made for the actual dimensions of mattress supplied which will be within 2cm.

Mattress Care

We hope you will be delighted with your new sofa bed mattress which should offer excellent service for years to come. All of our sprung mattresses are 2 sided so the mattress can be turned end to end and flipped over periodically to ensure even wear of the fillings within the mattress. During the first few months, a characteristic known as mattress settlement will occur - the fillings will compress where the user's weight is greatest, usually in the centre of the mattress. This is entirely normal and not a fault of the mattress - an explanation of mattress settlement can be read in this excellent Bed Federation article (click here to read).

Our memory foam mattresses are 1 sided and do not require flipping over, however as with the sprung mattresses rotating end to end is recommended on a regular basis.

Comments: I spent literally years trying to get a replacement mattress for my lovely sofa bed - then I came across this website and found the right thing! It arrived today and it fits perfectly. I went for the small single Deluxe Sprung, as it's only going to be used very occasionally and also of course to make the sofa comfortable to sit on. I find it very comfortable to lie on, and I'm 5' 9" and 10 stone. bigger people may find it less comfortable, (I don't think my 17 stone husband would love it), but for what I need it for I'm completely happy, thank you.

Comments: I decided to order a memory foam mattress to replace a DFS sprung mattress I had, as I felt it would be more comfortable and give more support.I rang to check re sizing, suitability and delivery dates and the advisor was very helpful and reassured me that the mattress should fit the type of 2 fold bed mechanism I had.I was informed that I could return it if any problems.However,I needn't have worried, as it fits perfectly and is very comfortable and supportive and far superior to the previous DFS one I had. I was very pleased that I could choose a specific delivery date, but did ring first to clarify that the mattress was in stock.The delivery was as scheduled by courier and arrived well packaged.Overall, I am very pleased with my experience of using the Sofabed Gallery.Thank you
