Get these five questions wrong and an ottoman bed becomes a ten-year regret. Get them right and it's the best storage you'll ever buy.
Before buying an ottoman bed, ask five questions: will your mattress work with the gas-lift mechanism, which direction does the base open and does your room have space for it, what is the base actually made of, who is going to assemble it, and what does the warranty cover — especially the lift mechanism itself. Those five answers separate a bed that opens with two fingers for a decade from one that groans, sags and eventually refuses to close. Here is the full pre-purchase checklist, in the order that matters.
1. Will my mattress actually work with the gas-lift?
This is the question most people never think to ask, and it is the one that decides everything. An ottoman bed lifts its entire mattress platform on gas-filled pistons — the same engineering that holds a car boot open. Those pistons are rated for a specific load, measured in Newtons, and as a rule of thumb the mechanism on a well-made ottoman is built for a mattress in the region of 40 to 60 kilograms. Go heavier than the struts are rated for and the lid becomes a two-person job to lift; go far lighter and the base can spring up with more enthusiasm than you'd like.
Mattress depth matters too. Most gas-lift systems perform at their best with a mattress up to around 25 centimetres deep; taller mattresses can still work, but the pistons need to be specified for them from the start. Every Belsogno ottoman uses hydraulic pistons calibrated for the weight of a full-depth mattress, tested to rise smoothly and — just as importantly — to stay open securely while you reach in. Before you order any ottoman, from anyone, find out the exact weight of your mattress and put it next to the frame's stated capacity. If you're choosing both at once, our hand-tufted mattress range lists every specification you'll need for that sum.
2. Which way does it open — and does the room have space for it?
Ottoman beds open from the foot end or from the side, and the right answer depends entirely on your room. An end-opening base needs clear floor space beyond the footboard; a side-opening base suits a bed pushed lengthways against a wall, which is common in loft rooms and compact city bedrooms. Stand in the room and picture the platform raised: you'll want roughly 30 centimetres of clearance above the highest point of the lifted mattress, which is worth checking under sloped ceilings before you fall in love with a frame.
It sounds obvious written down. It is also the single most common reason an ottoman disappoints after delivery — not the bed, but the ten minutes of measuring that never happened. Our guide to how ottoman bed frames work walks through the measurements size by size, from a 90×190cm single to a 180×200cm super king.
3. What's underneath — a solid board, or slats that will sag?
Lift the lid in a showroom, or read the specification online, and look at what the mattress actually sits on. Cheaper ottomans use widely spaced slats or a thin hollow panel; both flex under a heavy mattress, and a base that flexes will eventually dip, taking your mattress's lifespan down with it. Belsogno ottomans are built with a reinforced solid mattress board instead — a flat, stable platform that supports pocket-sprung and memory foam mattresses evenly across their whole surface.
Then look at the storage box itself. A full ottoman base gives you the entire footprint of the bed, typically 40 to 60 centimetres deep — enough for a winter's worth of duvets, two suitcases and the spare linen that currently lives on top of the wardrobe. There's a small tailoring detail worth checking here, too: whether the inside of the box is lined. A Brescian tailor finishes the seams no one will ever see, and we upholster the interior of the storage compartment for the same reason — so bedding slides in and out without snagging, year after year. For the longer story of where these beds came from, our piece on the origins and types of storage beds is worth ten minutes with a coffee.
4. Who is going to assemble it?
An ottoman is the most mechanically complex bed frame you can buy, and the gas pistons must be fitted exactly as the instructions describe — a strut installed under tension at the wrong angle is the fastest way to void a warranty. Every Belsogno bed arrives in modular sections (headboard, footboard, side rails and storage base) with all high-tensile bolts included, and most customers assemble one comfortably in an afternoon; our bed assembly guide covers the sequence step by step. If you'd rather not, choose the White Glove Delivery & Assembly upgrade at checkout and our team will carry it to the bedroom, build it, and take the packaging away. Standard free delivery is kerbside to UK mainland addresses — England, Wales and mainland Scotland.
5. Who made it — and what happens if the mechanism fails?
A gas strut is a consumable in a badly made bed and a fit-and-forget component in a good one. Before you buy, ask two things: who actually built the frame, and does the warranty explicitly cover the lift mechanism, not just the frame and fabric. Vague answers to either are your cue to keep looking.
Our answer is a straightforward one. Belsogno ottoman beds are hand-finished in our Yorkshire workshop in Liversedge and made to order, which is why they carry a two-to-three-week lead time rather than sitting flat-packed in a warehouse — your fabric is cut when you order, not before. You can choose from more than fifteen designer fabrics, from stain-resistant velvets to linens and bouclé, and we'll post a free swatch pack to your door before you commit; order your fabric samples here. If spreading the cost suits you better, 0% instalments through PayPal and Klarna are available at checkout — the bed doesn't mind waiting for the rest of the room to catch up.
Quick answers before you decide
Can a mattress be too heavy for an ottoman bed? Yes. Gas-lift pistons are rated for a specific load, and a mattress beyond that rating makes the base hard to lift and strains the mechanism over time. Check your mattress weight against the frame's stated capacity before ordering.
Do ottoman beds hold as much as they claim? A full gas-lift ottoman gives you the entire footprint of the bed as storage — on a king size, comfortably enough for several duvets, pillows and two suitcases — where a drawer divan gives you only the drawer volume. If you're weighing the two, our complete ottoman buying guide compares them in detail.
Are ottoman beds safe? A properly specified mechanism rises under control and locks open securely, hands-free. The risks come from under-rated struts on cheap frames — which is exactly what question one and question five are there to catch.
Five questions, one honest conversation
If you can answer all five with confidence, you're ready — and an ottoman bed genuinely is the best storage most bedrooms will ever gain, the kind of quiet efficiency the Italians call sprezzatura: a tidy room that looks effortless because the work is hidden under the mattress. If any of the five still feels uncertain — mattress weight, opening direction, ceiling height, fabric — that's precisely what we're here for. Book a free design consultation and one of our team will talk through your room, your mattress and your ottoman storage bed options before you spend a penny.
