What is a full size mattress?

Mattresses come in a variety of different sizes and whilst you may be familiar with a twin, queen or king, the full size mattress is right in the middle of that size spectrum. 

A full size mattress is larger than a twin but smaller than a queen, making it perfect for singles who want a bit more space or couples who want to save space within their bedroom. A full size mattress is also known as a double mattress and measures 75 inches long and 54 inches wide (for those who like to work in centimetres that's 191cm long and 137cm wide). 

It's worth noting that not all mattress brands make beds in a full size and instead jump straight from twin to queen. If you're unsure what bed size is best for you, take a look at out twin vs full size mattress buying guide and our full vs queen size mattress buying guide

1. DreamCloud Hybrid mattress:

1. DreamCloud Hybrid mattress: Was from $1,199 | now $599 for a full size mattress at DreamCloud
The DreamCloud is one of the best value luxury hybrid mattresses on the market and regularly tops our list of the best hybrid mattresses. During our DreamCloud Hybrid mattress review, our tester found this an excellent choice for sleepers who experience back and hip pain, but also a good buy for hot sleepers who will enjoy the heat-wicking properties of the gel-infused memory foam combined with the additional airflow that comes with the layer of coils. You can grab an absolute bargain during the Memorial Day sales as a full size mattress is down to just $599 from an original MSRP of $1,199 - that’s a cool saving of 50%. Yes, this 50% off saving from DreamCloud is one we're used to seeing but still exceptional value, and that's even before you factor in the generous benefits on offer here - a 365-night sleep trial, forever warranty and free shipping and returns. 

2. Tuft & Needle Original:

2. Tuft & Needle Original: Was from $795 | now $635 for a full size mattress at Tuft & Needle
This basic all-foam mattress is perfect for anyone who wants a no-frill bed from a luxury mattress brand at a bargain price. During our review of the Tuft & Needle Original, our tester found this mattress perfected really well when it came to pressure relief and also did a good job of absorbing motion transfer so ideal for couples or anyone who shares their bed with a pet. The Tuft & Needle Original was a great price to begin with costing $795 but during the current sales, you can get $160 off taking the cost for a full size mattress down to just $635. Tuft & Needle runs regular sales throughout the year and although we’ve seen them reach 30%, this current 20% saving is pretty average and you’re unlikely to see a deeper discount until the major pre-Christmas events like Black Friday or Cyber Monday so if you want it, it’s best to act fast. With Tuft & Needle you get plenty of time to see if you like this mattress with a 100-night sleep trial.
