Initially ordered a king size mattress for an existing bed frame inherited from a house sale! upon close inspection the frame wasn't very stable and couldn't be tightened up! so back onto the website which has an excellent choice of beds and mattresses all at competitive prices.It's early days but we are very pleased with our new mattress and bed.Items delivered two days after ordering.

Do Bunk BedsDo Bunk Beds Need A Special Mattress?Need A Special Mattress?

Making the most out of the vertical space in a bedroom, the best children’s bunk beds have a special place in the hearts of many youngsters. Contrary to popular belief, there’s not necessarily any need for a specialist bunk bed mattress.

Depending on the children’s bed in question, correctly sized conventional mattresses will do the trick. However, to make the most out of a bunk bed foam mattress, there are factors to consider which illuminate the differences between bunk bed mattresses and traditional mattresses.

What Is The Difference Between A Bunk Bed Mattress And A Regular Mattress?

There are different considerations to make when applying an everyday mattress for a bunk bed. Namely, mattress thickness. Bunk beds for children feature safety rails on the top bunk, preventing the child from rolling out of bed in their sleep, causing injury. It’s imperative that you match the mattress to your bunk bed size and take care to ensure that its thickness and height doesn’t exceed that of the safety rail.

Finding the most comfortable bunk bed mattress for a toddler or kid is a balancing act, as the padding offered by thicker bed bases can create a soft sleeping environment. Always put safety first when choosing cheap bunk bed mattresses and select a suitable thickness.

You can be more flexible with a bottom bunk mattress if safety recommendations are adhered to. Our affordable bunk bed mattress range is packed with the safest bed bunk beds for children. Choose from our high quality range and improve the quality of your little one’s sleep.

How Deep Should A Bunk Bed Mattress Be?

While weight limits and ages should also be considered, as a middle ground and general rule of thumb, 6-inch-thick bunk bed mattresses are the standard. This may differ on a bed for a toddler or teenager, as their needs will be slightly different due to weight and height.

Top bunk mattresses should never exceed 7 inches unless the bunk bed safety rails are much taller than usual. This doesn’t mean there’s any need to limit your kids to a thin bunk bed mattress, however, as our comprehensive range features a full roster of thicknesses to suit all age groups.

We also have varying firmness levels, from soft to firm, with models such as memory foam, allowing your youngsters to receive the best in night time comfort.

How Much Is A Bunk Bed Mattress?

There’s no need for an elevated price when it comes to buying a mattress for a bunk bed. Our budget bunk bed mattresses range between £100 and £220 and have the requisite quality to last for years of regular use.

With the savings you make when shopping with us, why not add a comfortable and luxurious pillow, duvet or mattress protector to your mattress for kids to create the most relaxing sleeping environment for their big dreams to flourish.

Can Adults Sleep In Bunk Beds?

Why let the children have all the fun? Bunk beds for adults have increased in prominence, particularly in areas which are low on space. Double-decker beds don’t eat away at your floor space, making the ideal sleeping solution where space is at a premium.

Similarly, our range of small double size bunk bed mattress and single bunk bed mattresses can be used by adults. If you’re looking for a bunk bed mattress for hostels, dorms and other shared accommodation, our double-decker bed mattress bring premium levels of comfort with a low-end price tag.

What are the British Standards of Safety for bunk beds?

Bunk beds sold in the UK must meet British Safety Standards. These regulations include:

  • Bunk beds must be solid in construction
  • Bunk beds cannot have sharp corners or edges
  • The mattress must securely fit the bed frame
  • Slats underneath the mattress cannot be closer than 7.5 cm apart
  • The upper bunk must have guard rails protecting both sides. There also needs to be a 300mm gap for access
  • Bunk beds must meet strict regulations about gaps in the construction, to stop children falling between rail and mattress, or getting stuck
  • The ladder to the top bunk must be firmly fixed to the bed
  • Ladder rungs should be a minimum of 3cm wide and 20cm apart
