Single Memory Foam Mattresses

Need help finding the right mattress? We've answered some of the most frequently asked questions about single memory foam mattresses to give you all the information you need to choose the perfect option with confidence.

A single memory foam mattress is the same size as a standard UK single mattress and is made of a unique viscoelastic material designed to respond to your body. Memory foam softens with your natural body heat, allowing the surface to gently mould to your shape throughout the night. This contouring effect provides excellent support, helping to relieve pressure on key areas such as the shoulders, hips, and back. They can be made entirely from layers of foam or combined with springs or other comfort fillings to create hybrid mattresses that offer both contouring and enhanced support.

Single mattresses are 90cm x 190cm or 3’ x 6’3” in size, making them the ideal choice for children, teenagers or in smaller rooms. A 3ft mattress is also great for a spare room, allowing guests to sleep in, making it a versatile choice. It’s always a good idea to check the measurements of your bedroom first to ensure a mattress will fit with enough space to move around the room.

If you have struggled to find a mattress that suits you, a memory foam mattress could be just right. There are many benefits offered by a single memory foam mattress, including:

• Responsive memory foam material: the innovative material forms itself around your body while you sleep so that you can rest as comfortably as possible. Since memory foam absorbs movement, you’re less likely to be disturbed by tossing and turning.
• Space-saving and practical for small rooms: a single mattress is a great option if you have a smaller bedroom to furnish, as you’ll have enough space to sleep comfortably without sacrificing too much floor space.
• Spinal alignment and support: the memory foam moulds to your body, reducing pressure and helping prevent aches and pains. You’ll feel supported as the material reduces pressure points to relieve aches and pains in your spine, hips and other joints.
• Durability and shape retention: unlike other mattress types, a high-quality single memory foam mattress tends to keep its shape longer and avoid sagging over time.

Consider our hybrid mattresses if you don’t want to fully commit to a memory foam mattress. They feature a combination of foam with pocket springs, so you can have the best support from both worlds. If you’re still unsure, consult our mattress buying guide for further tips on finding the best mattress.

In most cases, a good quality single memory foam mattress should be replaced every six to eight years. However, the support your child needs from their mattress depends on what stage of life they’re at. For this reason, we recommend replacing your child’s mattress every three years between 3 and 10 years old and changing it every five years between 10 and 16 years old.

Our single memory foam mattresses are available in all our most popular firmness levels, including:

• Soft
• Soft-medium
• Medium
• Medium-firm
• Firm

You may notice memory foam described as either “low density” or “high density.” This refers to how much foam is packed into each cubic foot, which directly affects the mattress’s firmness and feel. High-density memory foam contains more material, making it heavier, more durable, and more supportive. Lower-density foams, often found in softer mattresses, tend to feel more responsive and return to their original shape more quickly.

To choose the best memory foam single mattress, look for features that suit your body and needs. Here are some key considerations:

• Firmness level: side sleepers often prefer a soft mattress, while back and stomach sleepers tend to benefit from medium to firm options.
• Material composition: high-density foam mattresses typically offer better durability, while gel options enhance breathability.
• Body weight and sleep position: heavier sleepers often need a firmer, higher-density mattress, while lighter sleepers may prefer softer options.
• Temperature regulation: look for technology designed to regulate your body temperature to maintain a comfortable sleep environment.
• Budget: Happy Beds offers a range of single memory foam mattresses to suit every budget.
