6 Best Mattresses For Heavy People 2022 + Discount Codes

If you’re heavier than average then you need to take extra things into account when buying a new mattress.

The general rules are that a large person needs a mattress which:

  • is deeper than average (25cm or more seems to be the suggestion from most guides).
  • is medium/firm or firm.
  • has a high spring count if you want a pocket spring mattress (around 2000 springs ideally).

We’ve picked six mattresses which tick those boxes which have won awards, received good reviews or are from the best names in the mattress market.

​Prices are for double mattresses and are correct at the time of writing.


1. Nectar Sleep Memory Foam Mattress – £749 – 46 stone weight limit

**Nectar Sleep Jubilee Sale: 45% off until 22/05/22**

Nectar Sleep offers the longest warranty and the longest trial period that I’ve seen in the mattress market, so it’s certainly worth a look. It’s one of those ‘bed in a box’ mattresses which arrives squashed up and then expands in your bedroom. 

If you change your mind about it in the first 365 days you can return it, and if it develops a fault they’ll sort it out regardless of how old the mattress is (have a read of the small print as to what the warranty covers).

It’s made from five layers which aim to offer the benefits of consistent memory foam support. Some people find old-style memory foam makes them feel a bit hot, but these modern mattresses add things with fancy names like an ‘adaptive cooling cover’ and ‘smart memory foam’ which aims to get around that.

Reviews are very positive (4.4/5 on TrustPilot) and it’s won awards from Good Housekeeping and other independent expert testers. It is medium firmness (6/10 according to most guides, with 1 being soft and 10 being very firm).

Leading weight limit

It has a 46 stone weight limit ‘with no discernible loss of comfort or support’ according to the official info. It goes on to say ‘The secret is the breathable base layer, which measures a 2.2 ILD rating where other mattresses top out at a 1.5′. In case you’re interested, ILD stands for Impression Load Deflection’ which is a measure of firmness.

Sorry, I’m drifting into jargony waffle, but you get the idea.

Here’s the section from the Nectar website with more details. It’s the US version of the site, so we’ve converted pounds to stone.

2. Simba Hybrid Mattress – £919 – 36 stone weight limit (18 stone per person)

The Simba Hybrid mattress is a good option for a couple who are both larger than average as it can cope with a total of 36 stone according to their website. However, it’s worth realising that the 10 year warranty will only be valid if you both weigh under 18 stone (114kg).

The mattress has a medium/firm tension according to the manufacturer. It is is mostly foam but it also has a layer of small ‘miQro’ springs for a bit of extra comfort. 

It makes our list because it’s won multiple awards (‘more awards, from more experts’than any other mattress brand according to Simba) and it gets really good customer reviews. At the time of writing, the Simba brand scores 4.4/5 on TrustPilot. Meanwhile, The Simba Hybrid scores 4.4/5 on Amazon.co.uk or 4.8/5 on Simba’s website.

It comes squashed up into a box and has a very appealing 200 day trial so you can try it out for more than six months before deciding if you want to keep it.

Here’s a screenshot from Simba showing the full details of the weight limit.

3. ​OTTY Hybrid Mattress – £799 – 22 stone weight limit

Perhaps I need to get out more, but I always keep a close eye on the winners at the National Bed Federation Awards. In 2018, OTTY won Small Online Bed Retailer of the Year and their mattress is good value for the specification.

It’s slightly different from most ‘bed in a box’ mattresses because it’s halfway between being a pocket spring mattress and a foam mattress. 

It has 2000 springs which should provide a good level of support for a heavier person. It also comes with a 100 night trial, so you can return it for a refund if it’s not for you.

It’s been given very positive reviews by Good Housekeeping, as well as getting an award from independent experts in 2018. Customers rate it too, with scores of 4/5 on Amazon for the Hybrid model or 4.5/5 on TrustPilot for the OTTY brand overall.

4.​ Vispring Imperial Pocket Sprung Mattress – £2699 – 20 stone weight limit

£2699 for a mattress? My car’s worth less than that!

Anyway, Vispring invented the pocket spring mattress, so they know what they’re talking about. And broadly speaking you get what you pay for with a mattress.

We’ve included this mattress because according to various websites, a Vispring ‘firm mattress’ is suitable for people who weigh 16-20 stone. Most manufacturers don’t offer such helpful guidance.

The ‘Imperial’ has got a high pocket spring count (1700+ on the King Size version) whilst cheaper Vispring mattresses have fewer springs. If you’re heavier than average then you’ll get better support from a high spring count.

5. ​Tempur Sensation – £2249 – 23 stone weight limit

You’ll pay a premium for a Tempur mattress, but their mattresses have an unrivalled pedigree and the ‘mattress weight capacity is approximately 150kg per side’ (that’s 23 stone or 320lb).

Tempur is the biggest name in the memory foam mattress market after developing NASA technology. Reviews of the Tempur Sensation mattress are strong, averaging 4.5/5 on Tempur.com, 4.9/5 on JohnLewis.com, 4.8/5 on Dreams. Overall, Tempur was scoring 3.7/5 on TrustPilot (as of 2022).

Tempur Sensation mattresses are the firmest option in their range so should offer better support for an overweight person (heavier people will sink into a soft mattress too much). It comes in three thicknesses with three price tags. I would go for the 30cm deep version, rather than the cheaper 21cm version if you can afford it.

6. Ergoflex 5G Memory Foam Mattress – £809 – 18 stone weight limit

The Ergoflex 5G memory foam mattress doesn’t have a massive weight limit, but it’s a highly rated mattress which at least offers guidance. 

It’s another ‘bed in a box’, meaning it arrives squashed up into a box. It has a decent claim as being one of the highest rated foam mattresses around and comes with a generous 10 year guarantee. Its current TrustPilot score is 4.7/5, which is about as good as it gets. 

You get a 30 day trial period, which is less than some of its rivals but probably enough time for you to figure out if it’s right for you.

It’s medium/firm and has a top layer of memory foam which is 9cm deep. Without wishing to get too technical and boring, it’s worth saying that this is a good sign. Cheap memory foam mattresses only offer 2cm or 3cm of memory foam with other types of foam underneath.

Regarding the weight limit, Ergoflex say that ‘the mattresses are suitable for persons up to 18 stones in weight (approx. 114 kg or 252 lbs) or 30 stones for combined weight (approx. 190 kg or 420 lbs)’. The limit is only described as a ‘precaution…to ensure ongoing maximum performance’ and the website says to call them if you weigh more than that, so they can offer advice.

Here’s a screenshot from the Ergoflex website with more information about the weight limit.
