FAQ

Frequently Asked Questions - Memory Foam Products
  1. Are Cosynight memory foam mattresses ok for slatted bases?

    Yes any bed base that is firm is ideal, the slats will not cause any problems.

  2. Can I use an electric blanket?

    In the long term it can break down the memory cells, but is ok to use one just to warm the bed and not leave it on all night.

  3. What does 60Kg/m3 mean?/ Is it better to go for higher density?

    The higher the kg/m3 the higher the density of memory foam.

    Contrary to some mis-information communicated by a number of suppliers, it is not always better to go for a higher density. When choosing a memory foam mattress (or any other mattress for that matter) 'comfort' or 'feel' plays an important part. Naturally, the higher the density, the firmer the mattress. However, very few people feel comfortable on very firm mattresses. As a matter of fact, most people prefer a medium-to-firm feel. Also, the 'support' your mattress provides is equally as important as how it 'feels'. Most people who suffer from back pain will benefit from a more supportive memory foam mattress than one with less support as it will keep the spinal column in the correct anatomical alignment and therefore alleviate pain caused by a contorted sleeping position.

  4. Do your mattresses have a mattress cover? / What is Stess-FreeTM fabric?

    Yes. all Cosynight memory foam mattresses come supplied with a special zip-off cover. Cosynight tailor-make the covers for all our mattresses from Stress-FreeTM fabric which is a four-way stretch fabric that has been specifically designed and woven for foam mattresses.

  5. Is the memory mattress good for bad backs and joint problems?

    Yes, a memory mattress will help to support and cushion the problems making it more comfortable to sleep.

  6. Do memory mattresses get hotter than normal mattresses?

    No, the memory foam is breathable. However, due to the way in which memory foam works more of your body is in contact with the sleep surface which greatly enhances pressure relief due to the body's weight being dispersed over a greater area. This increase in body-contact will naturally result in a 'warmer' or 'cosier' sleep experience which is welcomed by most people (especially in winter). If you prefer a cooler sleep surface or you suffer from excessive sleep perspiration then it is worth considering Cosynight's advanced "Air Bounce" mattress which has been designed with you in mind.

  7. What are the mattress sizes in cm?

    The following is a list of our standard mattress sizes

    Single:90 x 190 cm3'0"x 6'3"
    Double:135 x 190 cm4'6"x 6'3"
    King Size:150 x 200 cm5'0"x 6'6"
    Super King Size:180 x 200 cm6'0"x 6'6"

    Cosynight's mattresses are also available in all other non-standard sizes (i.e. four-foot, IKEA, adjustable-bed etc). In fact, we can supply you with any size or shape of mattress you want.

  8. Are they OK for adjustable beds?

    Yes they are fine. The memory mattress will conform to the underlining base.

  9. Can you use a memory foam topper on its own?

    Yes you can. Some customers have bought them to use when camping or to use as a spare mattress for guests. However, to get the full benefits it is best to use a soft base.

  10. Can you use a memory foam topper with a SOFA BED?

    We have supplied memory foam mattress toppers to many satisfied sofa bed customers. The foam mattresses which come supplied as standard with most sofa beds will never give the required support for a half-decent night's sleep.

  11. When my memory foam pillow and overlay arrived they where quite hard. Why?

    One of the characteristics of visco elastic foam is its reaction to temperature. Cold temperature makes the foam much firmer. Once the foam is exposed to room temperature and your body heat the foam will become supple and supportive. You should allow up to an hour at room temperature to allow the foam to soften before use.

  12. Can memory foam be dry cleaned or machine washed?

    Do not machine wash or dry clean visco elastic foam. You can only spot wash the foam by hand and let dry naturally on a flat surface. Do not place into a dryer.
