Every bedroom has the same problem. The winter duvet that needs to live somewhere between May and October. The spare pillows for guests. The towels that will not quite fit in the airing cupboard, the kids' toys that migrate upstairs, the shoes you wear twice a year. It all has to go somewhere, and for most households that somewhere is the top of the wardrobe or an overstuffed drawer that no longer closes.
An ottoman storage box is the simple answer, and it is one of those purchases people wish they had made years earlier. But before you buy one, the obvious question is the practical one. How much does an ottoman storage box actually hold? Here is an honest look at capacity, size by size, along with what tends to fit and what does not.

What Is an Ottoman Storage Box?
Think of it as a blanket box brought up to date. Our ottoman storage boxes are built on a solid frame and base, topped with a cushioned, upholstered lid that lifts on metal hinges with a sturdy strap. The whole thing is upholstered in the same soft, easy-clean fabrics as our bed bases, so it looks like a piece of furniture rather than a plastic tub.
Because the lid is cushioned, it earns its keep twice. It is a storage chest and a seat at the same time. Placed at the foot of the bed it becomes the spot where you sit to put shoes on, and in a guest room it doubles as extra seating whenever anyone stays.
Capacity by Size: What Actually Fits
Our storage boxes come in six widths to match standard bed sizes, from single through to super king. Sizes are named after the respective bed width - so a single storage box would size flush, without any overlap, at the end of a single bed. Please check the dimensions on each product page before ordering.
Single
The single size suits one clear job done well. A folded single or double duvet, or a couple of spare pillows with some bed linen tucked around them. In a child's room it swallows a surprising amount of toy clutter, and because the lid is hinged rather than loose, tidying up takes seconds.
Small Double / Double
This is where the box starts absorbing a household's seasonal overflow. A folded double duvet plus a set or two of bedding, or your out-of-season wardrobe layer, think jumpers and hoodies, folded flat. It also works well as a linen store, holding towels and spare sheets in one place instead of three.
King Size
The king size comfortably takes a folded king duvet with room around it for pillows or bedding sets. This is the size most couples choose for the classic summer swap, where the heavy winter duvet goes in around May and comes back out in October, with the lighter one taking its place in between.
Super King
The largest box in the range holds serious volume. A super king duvet plus spare pillows, or a full guest bedding setup, duvet, pillows and linen, ready to lift out when visitors arrive. If your storage problem is genuinely big, this is the one that makes it disappear.

Getting More In: Three Habits That Double Your Capacity
Whatever size you choose, how you pack it matters as much as the box itself. Vacuum compression bags are the biggest single upgrade, shrinking a bulky duvet to a fraction of its size and protecting it from dust at the same time. Folding flat rather than stuffing keeps the space usable right into the corners. And storing by category, bedding in one box or shoes in another, means you never have to empty the whole thing to find one item.
One thing worth saying plainly. Anything you store should go in clean and dry. A sealed box keeps dust out beautifully, but it will also keep moisture in, so wash and fully dry bedding before it goes away for the season.
Storage Box or Ottoman Bed? Choosing the Right Tool
If you are weighing up a storage box against a full ottoman bed base, the honest answer is that they solve different sizes of problem. An ottoman bed opens up the entire area under your mattress, which is the largest hidden storage space in any bedroom, and it is the right call if you are replacing your bed anyway or the clutter problem is severe.
A storage box, on the other hand, needs no new bed, arrives ready to use, and adds seating as well as storage. Plenty of our customers end up with both, using the bed base for bulky seasonal items and the box at the foot of the bed for the things they reach for weekly.
Built Properly, Delivered Properly
Every box in our ottoman storage box collection is Made in Britain by expert craftsmen, with a solid frame rather than the flat-pack chipboard construction you find elsewhere. You can choose an upholstery to match or complement your bed base, from the smooth suede feel of Naples to soft Plush Velvet and cosy Chenille, in colours across the range.
Delivery is taken care of too. Complimentary two-man delivery brings the box to your room of choice within 3 to 10 working days, so there is no wrestling a heavy piece of furniture up the stairs on your own.

The Short Answer
How much can you really store? A season's worth of bedding in the smaller sizes, and a full guest setup or an entire seasonal changeover in the larger ones, more still if you pack with compression bags. For the amount of clutter it removes from view, an ottoman storage box takes up remarkably little room, and it gives you somewhere to sit while you admire the tidy bedroom it leaves behind.
